While scrolling through social media, we often stumble upon fun and quirky facts that make us smile or shrug. But then, there are those facts that make you pause and wonder, “Wait…is that really true?” So when a curious Redditor asked, "What’s a fact you learned that instantly made you question reality?" people flooded the thread with some of the most jaw-dropping facts they’ve ever encountered. Ready to have your mind blown? Keep reading, Pandas!

I read somewhere that we can only see about 0.0035% of the electromagnetic spectrum, meaning we’re practically blind to most of what’s going on around us. It made me question how much of reality is hidden from us, existing beyond what our senses can perceive.
Another one that shook me was learning that trees can communicate with each other through underground fungal networks, sharing nutrients and even warning each other about threats. It completely flipped my understanding of forests — they’re not just a collection of individual trees, but more like an interconnected community working together. Reality suddenly seemed a lot more complex.
I'm an arborist and have been for 20 years. When I learned about the biology of the trees I started feeling more like a vet/Dr than a laborer...
Then OP might even more be shocked that crops do the same, with pheromones. If plants in one end of a field get nibbled on, they send warning signs, so other plants can start a defensive action. Usually the sap is getting bitter, so they are less tasty. Due to modifications, most crops are muted today. In combination with giant monocultures, without any shelter and breeding areas for "good" birds and insects nearby, more chemicals and gene-manipulation are necessary. In some countries, it spiraled out of control. And that the wkrld population went from 2.5 billion in 1950 to 8 billion today doesn't help either.
You came up with a great name for a Rock Group: "The Underground Fungal Networks"
There is a strong argument for Gaia and Douglas Adams' "interconnectedness of all things". We are all part of a giant computer!
We can only see light in a limited spectrum, but can also experience sound and have built devices that let us see into other parts of the spectrum - radio telescopes, infrared and ultraviolet cameras, ultrasonic devices (e.g. bat detectors). And we are slowly learning to supliment our senses with coclear implants and even artificial vision. It cannot be long before we use these technologies to augment our senses to "see" more of the spectrum. Predator is not *that* far fetched!
Check out a book called Braiding Sweetgrass. Weaves together Indigenous knowledge and science. She discusses this phenomenon
Such a great book! I am convinced the Indigenous populations can help us replace our current culture of overconsumption and every man for themselves with a knowledge of how to be in the world where humans are not the deciders of what gets to live and what gets to die. Another great read is Ishmael by Daniel Quinn.

Our brains would be overwhelmed to be able to see *everything* happening around us; instead, we get to see , and hear, and smell, and taste the best things.
They can also team up and single out another tree by drawing away it's source of water.
That some people don’t have an inner monologue or voice; and that some people literally can’t picture things in their minds.
People can’t picture things in their minds? Wow, that must be really different. I can't visualize it.
I can't picture anything in my mind.. I'm an avid reader, but it's just words to me, I didn't know until recently that people could actually see what they're reading in their heads..
I can't see anything in my mind. I didn't realize anyone could until lately just thought it was a figure of speech. I make up for it with an inner dialogue that incessantly spews out useless sometimes negative c**p. I tell it to shut the f**k up but apparently I won't listen to me.
Most people are able to picture things in their mind, including me, and it's not a figure of speech. The fact that some people can't is mind boggling to me.

What about a light show on the insides of your eyelids when you close your eyes to go to sleep? Anyone else have that?
Yup. Do you have glitter twinkling in your eyesight? My vision looks like a kolidoscope.(sp?) Just with crystal, irridecent glitter. That is not to be confused with a traditional aura that you get with most migraines. A never ending light show

I was raised Mormon. When I learned how much was copied from the Freemasons, I began looking at the non-church sources for information. Finding out your whole life has been a lie is a hell I wish on no one.
Any church is just a cult. People don’t need religion to tell them how to be a good person
For some it justifies SA.. just look at Stephen Collins (Seventh Heaven). Or use theism as an excuse to hate on some. Just yesterday I heard that some on a documentary said that Sodoma had nothing do do with homosexuality, that this was changed during the course of history to fit their narrative.
Load More Replies...Your first clue that it was all a lie should have been Joseph Smith's claim that he translated the Book of Mormon from gold tablets with the help of a magic hat and seer stone.
"i found these gold plates and only i can read them with these magic stones. and no, i will NOT let any one else see them!" he was caught cheating on his wife, so he told her that the magic plates said that he could have more than one wife, so he was not cheating.
The mythology of the Mormon faith was easily seen when a fraudster sold the church a bunch of forged documents allegedly made by Smith and other founding members. The church spent many thousands of dollars to keep these documents from leaking to the public. Their insistence about the lost tribes of Israel traveling to North American and establishing a doomed civilization has absolutely no archeological or genetic science to prove this was more than a J. Smith fever dream for grifting his followers.
religion is a disease that sprouts from fear, as Bertrand Russel once stated
I've read the Bible twice. Nothing in it makes me think any of it is real.
People are liars and that wasn't any different 2000 years ago. I said what I said.
When we sit down to eat, we often don’t think about the science or history behind what’s on our plate. But food is more than just something to fill us up—it’s full of surprises. From our favorite fruits and veggies to those delicious snacks we’ve been enjoying for years, there’s a lot more to food than meets the eye.
For instance, did you know that your beloved strawberries aren’t actually berries, but bananas are? These little-known facts about everyday foods can completely change the way we see our favorite snacks and meals.
The Romans figured out how to make heated floors. Central heating sounds like a modern invention, but apparently its been around for 2000 years.
I learnt about the Romans in school in 1969. We visited Chedworth Roman Villa as well. There are still stretches of Roman roads, aquaducts, viaducts and walls, all over Europe, still standing and still used today. That thing in "The Life of Brian", when they are sat talking about "what have the Romans ever done for us", is testament to their engineering.
I learned this from the author Diick Francis, in Decider.

There is still the term the "Dark Ages" referring to the years between the fall of Roman Empire (476) and discovery of the american continent by europeans (1492). In fact, those centuries were full of progressing and gaining knowledge in different fields of science. And of course, the period beforre the "Dark Ages" is considered by many even darker. Geez, people are really disappointing with their arrogance.
That's why s**t like "Ancient Aliens" gets made. Those fools don't credit humanity with any technological savvy.

That everyone you know or have met has a different version of you in their minds. Their perceptions are based on their interactions or impressions of you. No one really sees you exactly the same way.
But the way they treat you is based on what they think of you, and from there it is your business. This is my personal experience.
Load More Replies...And yet we tend to think the versions of other people *I have in my mind* are accurate representations of who they are
And the same is reciprocal for most. If you have the social skill you tailor your behavior and mannerisms naturally to your situation. Most people wear many faces of personality and use them as the situation is required.
My dad just died, my sisters and I learned so much about him from sorting through old pictures and talking memories with our mom, getting ready for the celebration of life. Some examples included finding out that him going to med school was a case of a friend saying "hey, I've got an extra application, want to apply with me?", the fee was $20 (in 1952), he won it in a poker game that night, sent off the application and got in thus leading to long, and illustrious career (not joking- he was a pioneer in a few things) or finding out just how much he helped a family from the Sudan immigrate to here and get on their feet or finding a picture of my paternal great-grandfather from 1876 & it's a dead ringer for one of my nephews.
My son is 5 now and I still look at him dumbfounded at times. Like I MADE you. You grew inside of me and now you exist with your own consciousness. And continue to grow. Crazy.
Erma Bombeck wrote that to be a mother is to have your heart go walking around outside your body.
That's how I felt after my nephew was born. It was a difficult birth and scary for a minute, but then all of a sudden he was out and alive. Then I had to go to work just like it was a normal day and I didn't just witness a straight up magical event. I still struggle with that and he's 8 now!
I think this all the time looking at my children, I was led to believe I would never conceive a baby .. then I miscarried in 2007 ..nothing for years, I'd get upset thinking my only chance had gone, 2016 my Daughter was born then 2021 my son..to me, they are miracles..like more than the whole creating them, how they are even here fullstop!
Literally think this all the time I'll be looking at my kids doing something anything and it just pops in my head that because me and their dad got it on I then grew them like a plant inside of me but a plant that would come out and when they talk walk and be their own little person it's insane to truly think about it when I start to like think about the genetics and the process of happening overwhelms my brain.... 😂
You are no more than bunch of atoms that are holding together with no apparent reason, forming complex structures, whilst having no mind of their own and no external regulation. Surrounded by other atoms, yet not mixing with them... That is a wonder I struggle to grasp
When I breastfed my kids I was so amazed by the fact that my body was giving them food to grow and thrive on. It was such a weird thought. My kids are feeding on something my body produces. They only have this source of food. And they are growing and learning stuff and.... it's all on me. Being super insecure about myself my entire life made breastfeeding such an amazing experience. I am the reason these 3 wonderful kids are here. I am the reason they continue to be here.
I still look at my 17yo Frat twin boys that way. I almost died at the beginning of my pregnancy from HG -- Modern Medicine kept me and them alive. Was told I would have been dead on the couch within 3 days, if not brought back to the Hospital for the 2nd time. They are to me my Miracle Babies.
Many of us enjoy eating classic berries like strawberries, raspberries, and blackberries, but here’s a twist—they’re not real berries at all! Surprisingly, bananas are scientifically classified as berries, along with eggplants, grapes, and oranges. Confused? You’re not alone!
The reason behind this mix-up is pretty simple: people started calling certain fruits "berries" way before scientists came up with a proper definition.
That there is no way to know for sure if you and any other person sees the same color when looking at the same thing.
When I had cataract surgery they did the eyes a week apart. During that week I could live in two versions of the same world. In one eye the toilet brush was all white in the other it was bright yellow bristles with a yellow insert. The sky was also different, grey instead of blue. I walked around for a week exploring the world I was leaving after the next opetstion
Yeah, the difference between cataract view and clear view is really something. I'm still dealing with the difference, my right eye isn't bad enough to get surgery yet.
Load More Replies...Well most of us roughly see the same colours. Thats why there are paint charts. But what one perceives can be different. And the colour on a computer monitor and printed arent the same either.
It's been a while, but while humans have three color cones there are discrepancies between person to person in regards to perception due to the number of [whatever] each cone we all have carries.
You know those fun universe animations that starts out with the earth, or maybe something on earth, then zooms out bit by bit, comparing us to something larger in the universe? Then it keeps going. You can't see earth anymore, but you can focus on the sun. But then the sun is gone. And we're still getting smaller because we haven't gotten to the biggest object yet. Smaller and smaller and smaller. We barely even exist. But I complain about the drive to Dallas.
I don’t have any relatives in Dallas. Does that mean I don’t have to drive there?
Load More Replies...Totally normal. In those far far galaxies, on a planet with two suns, there is sure someone complaining about getting from A to B.
There are 300 billion stars in the Milky Way galaxy. There are a trillion galaxies in the VISIBLE universe. That means there are over 300,000,000,000,000,000,000,000 stars in the visible universe, which is a quadrillion times the 30 trillion cells in the average adult's body. If the Earth explodes today, the universe will not notice it any more than you notice a single cell dying in your body. Nothing you do has any real effect on the universe. You are insignificant.
I mean, that drive kinda sucks. With love from the other side of Lake Ray Hubbard.
Pffft, Dallas. Amateur. There are unlucky people in this world that have to drive to Baltimore. Every weekday.
I read about a dr who had a near death experience and said his spirit went to the moon and back. So when I go, I’m planning on visiting the pillars of creation
Not really a fact, but a feeling. I was raised in a religious setting, so the question became "If God made everything, who made God?" I used to spiral into these thoughts, like "How does the universe exist?" "Where did everything come from?" "How is it possible to exist? Nothing can exist!" I eventually learned about dimensionality and stuff and put it to bed with the fact that whatever the answer is, I have no capacity to understand it anyway.
I remember aged about 5 asking in scripture class, "Pease Miss, who was God's mummy and daddy?"
I remember as priest once said that Jesus always existed, and I asked how could he be born when he already existed. He told me that I will understand when I die.
Load More Replies...Once upon a time, I had all the answers. They were somebody else's answers that they got from somebody else, that they got from somebody else... somebody else ... and/or was their interpretation of answers from ancient books. Actually, sometimes those somebody elses had differing answers, so I struggled to determine whose were the most right, even while continuing to consider that I had all the answers. My fellow answer-holders and I felt bad for those who had some different answers, completely different answers, or 😱 no answers at all! Then one day, upon closer inspection, I realised that the very foundations of my answers didn't align with the evidence of history, truth, or reality. Now, I have no definite answers. I have guesses and hunches, intuition with a dose of "I could be wrong". Overall, I'm free to explore the MMRPG of life and find out stuff without trying to make it fit my answers. And that's way better.

That God is eternal, always was and always will be, and we cannot understand such a concept because God did not create our world with the ability to understand this. BTW this was written down in a Jewish writing about 60BCE, and is the accepted understanding of God in Judaism since then.
According to Judy Jernstedt, a plant sciences expert from UC Davis, the word “berry” was used for centuries without a scientific explanation. But now, we know that for a fruit to be a true berry, it needs to have three distinct layers: the exocarp (which is the skin), the mesocarp (the juicy middle), and the endocarp (the part that holds the seeds).
These were both from when I was relatively young, 7 or 8. And obviously as a result of the religious environment I was raised in.
1. There are religions other than Roman Catholicism. I thought RC was just what everybody did.
2. People *actually believe their religions are true*. I thought that everyone else was just going along with things for whatever reason - as I was - because, even as a kid, none of it made sense. I quickly learned that questioning things just got you in trouble so did what I was told.
Ditto. As I got older, I was surprised on a number of occasions to learn people/places in the bible were real, as a kid, I'd assumed it was all fictional.
I mean some of the places are real but 95% of actions, people, deeds, etc. are complete fabrications. Anyone stupid enough to believe a man put 2 of every animal on a boat (that would need to be double the size of the largest ship man ever built to hold then all...) is either gullible or weak and needs a crutch to handle the challenges of daily life.

Growing up, neither my family nor the families of any of my friends were members of any religion. No one ever even talked about it. I was in my late teens when I found out that there were real people who actually believed in any religion. I thought it was a made-up thing on tv. Totally rocked my world.

Load More Replies...Actually my Bible teacher from my old school I'm pretty sure said you are able to question your faith bc everyone interprets the Bible differently, having a different denomination from another Christian is fine, for example I'm a Baptist and I go to a Catholic school so what I believe might be different from what my teacher teaches, it's fine
That's totally why I went on to do religious studies (academic, public university) for a masters cause the whole concept of "belief" totally dumbfounded me. I just didn't understand it. But I do sincerely appreciate that it's genuinely reality for many folks.
The church I went to had three categories of people: (a) Those that tried really hard to believe and would tell you that they believe, (b) those that said they believe because they'd get in trouble if they said otherwise, and (c) those that were forced or guilt-tripped to go to church. As near as I could tell, there were more people in the (c) category than (b), and more in the (b) category than (a).
Anyone who has ever played Chinese whispers knows that in 1 room of 20 people the message can change drastically from person 1 to person 20 in less than a half hour. Now let's take another look at all the oral traditional stories passed down generation to generation before finally the written word comes into being and a "learned scribe" puts it all on paper, with proper sentences and accepted written constructs required as well....literally "God" only knows what was said and done by "Adam and Eve", if anything worth noting was said or done at all.
Plus: 1) translating stuff back and forth will seriously alter it even with a skilled polyglot, let alone some eager but undereducated missionary whose audience knows even less than he does. And 2) eye witness reports are notorious for their inconsistences after serious incidents from accidents to major crimes. I doubt people several thousand years ago were THAT much better at reporting the objective truth and nothing but the truth.
Load More Replies...All the monotheistic big 3 from the Middle East are based on the oldest beliefs, borrowed, then tailored to the times. For example the old Semitic god Helel Ben Shahar and his twin Shalim are everywhere. Helel Ben shahar means god of the morning star and Shalim is god of the evening star. Through many iterations Helel eventually morphs in Lucifer the light Bringer and Shalim is where Shalom in Hebrew derives and Solomon, and Salem and other references. Both were borrowed renamed morphed until we have what we have now.
Raising children in a religious environment is a form of child abuse. You won't change my mind on this. There is far too much evidence that this is the case. Downvote me all you want. Doesn't change the facts.
That one about how bananas are berries but strawberries aren't really berries... like what even is fruit anymore.
Botanically speaking, fruit is the mature reproductive organ of a plant. Berries, seeds, drupes, nuts, melons…these are just some of the subcategories. Many modern fruits cultivated for human consumption no longer contain seeds and reproduce through manual intervention by budding, grafting, and other similar methods, but in the naturally evolved varieties, all fruits carry seeds. This is their purpose: to entice other organisms to consume them and leave the seeds behind in their droppings elsewhere later.
Tomatoes and eggplants are berries, therefore, fruits. Okra is also a fruit, apaprently...I was going to find out and write more, but this is a rabbit hole I've just decided to avoid.
If I can recall, it's all about botany and the plants producing from one single ovary. Correct me if I'm wrong, please.

honey can spoil. I got a new glas of raw honey from a beekeeper and forgot about it. When I found it in the back of my cupoard, The water and suger had split and it started fermenting. You could say I made a glas of mead in my cupboard.

Load More Replies...Honey can actually go bad if it’s low quality and other reasons. Honey naturally produces its own hydrogen peroxide which is a bacterial killer and has properties to retain water without losing it over time. The problem arises in poor quality honey that’s unfiltered and you risk botulism.
But i wonder if the water content change? If this can affect fermentation?
Load More Replies...Honey may be antimicrobial, but it can contain botulism, which is the last thing your want to be rubbing into a wound.
Load More Replies...Just like bananas, watermelon also fits the scientific definition of a berry because it has those same three layers. In bananas, the peel is the exocarp (outer skin), the flesh we eat is the mesocarp, and the little seeds inside are protected by the endocarp.
Watermelons have the same structure—though the exocarp is tougher, appearing as the thick rind, and the juicy red part is the mesocarp. Who would’ve thought that bananas and watermelons would have so much in common?

When you do a proper shuffle of a normal 52 card deck, the resulting shuffle order of the cards has a very near 100% chance of that being the first time that order has ever happened in the history of the universe.
In order to calculate the exact percent chance of being a first-ever order, you would need to know the number of times decks of cards have been shuffled. However, there is a 99.999999999999999999999999999999999999999999999999999999999999999998760200069142851407604965801105360671233740381709570936378473764561471114369242670321231350929093806287608708750528549344883853521288% chance of one shuffle being different from one other shuffle.
This one made me curious as to how many possible variations there could be so I asked Chat GPT and this is what it said: The number of possible variations for the order of a shuffled 52-card deck is given by 52! 52! (52 factorial), which is the product of all the integers from 1 to 52: 52! = 52×51×50×⋯×2×1 This results in an astronomically large number: 52!≈8.0658×10 to the power of 67 So, there are approximately 8.07×10 to the power of 67 possible ways to shuffle a deck of 52 cards! This number is so huge that it vastly exceeds the number of stars in the observable universe.
I watched an experiment where 1000 people sit in a room and shuffle all day, every day and the results are checked. I can't help thinking it's like the weird phenomena where 2 people with the same birthday are almost guaranteed to be together in a room of 23 people...
That’s true. The number of possibilities is 8 followed by 67 zeroes. That 8 sexagintasextillion.
Go play any collectible card game, such as Magic the gathering, or Pokemon, and shuffle your deck like normal. Watch how many times you draw the exact same hand, over and over and over. Happens to me all the time.
But do you draw the exact same hand in the exact same order. When drawing seven cards getting the same seven cards out of a deck of 52 is not as low of a probability, but then when you add in the order is when you start getting into the astronomical probability.
Load More Replies...By my rough calculation--100 billion year old universe, 100 billion people who've ever lived, one shuffle per second--there'd be around 100 septillion shuffles. That sounds like a lot, right? It is. It's so ginormous we can't really comprehend it. So let me say this: if the tallest person ever alive was shrunk down to one 100 septillionth of his size, he'd be about 20 rontometers tall (https://en.wikipedia.org/wiki/Orders_of_magnitude_(length)#10_rontometres). In short: big number. But not in context. The number of possible shuffles is over *10 to the 67th*, meaning the odds of someone else getting the same shuffle as you if you shuffled decently is 1 in *10^42*, roughly a thousand times "the probability that, when one of the Florida electors reaches into the hat to draw a name, he or she is struck by a falling cocaine bale, the hat is hurled away within the next few seconds by a tornado, and the elector is obliterated minutes later by a meteorite impact" (from what-if.xkcd.com/19)
Unless some aliens has used decks it is rather "those few hundred years" rather then the history of the universe.
Permutations. There are 52 possibilities for the bottom card in the deck, 51 for the one on top of it, 50 choices for the next, 49 choices for the one after that, etc. (You could start at the top as well, or any place in the deck.) The number of different orderings of a fifty-two card deck is 52 factorial (52!), which is 52 x 51 x 50 x 49 x .... x 5 x 4 x 3 x2 x 1. This is a bit more that 8 followed by 67 zeroes. The probability of repetition is one chance in that.

My physicist husband claims that there are differently-sized infinities. Apparently, a lot of mathematicians think that, too. HOW????
There's an infinite number of numbers between 0 and 1. There's also an infinite number of numbers between 0 and 2. However, there is twice as much room for numbers between 0-1 and 0-2. Adding infinitesimals hurts my head.
No, that's not why there are bigger infinities. There are an infinite number of whole numbers. And an infinite number of rational numbers. But you can write an algorithm to match every rational number to a monotonically increasing whole number. So those infinities are equal. However, you cannot do this for real numbers. There are always more potential real numbers than can be accounted for in a function. So the infinity of real numbers is larger than that of rational or whole numbers. I believe it's called the equivalency principle. I am not a mathematician
Load More Replies...An infinite number of elephants is bigger than an infinite number of mice.
Well there's infinity, and then there's infinity plus one. I wouldn't read too much into it, as mathematicians also believe in imaginary numbers! ;-)
Imaginary numbers are super important, and we use them for a ton of real world applications like digital signal processing, noise cancellation, compression algorithms, and tons of others. Infinity plus one isn't what's being referred to here. I explained it elsewhere
Load More Replies...When infinites come up in physics it usually means we've found a limit to our theories. True infinities don't really exist in reality. Some of the "universal constants" physicists use are assumptions about things we cannot prove or define adequately enough. As experiments continue to evolve we can refine theses theories. So how close we can get to defining these "infinities" could be viewed as differently-sized. Good example: a small group of researchers at a university recently discovered how to make a much more accurate clock than even atomic clocks that can be used to test some of these universal constants. A lot of scientists believe we're going to find out that they are not as constant as we think.
For fun, look up "surreal numbers" on Wikipedia. There are a whole lot more types of infinity there than most mathematicians think.
all the countable integers are Aleph-null infinities - if an infinitely large bus arrived with an infinite number of tourists to an infinitely large hotel that was full all you have to do is move all the guests from the odd numbered rooms to the even numbered rooms and you can accommodate an infinite number of new arrivals
If you’re a fan of peanuts, here’s a fun fact: you're actually snacking on legumes! That’s right, despite the “nut” in their name, peanuts belong to the same family as beans, lentils, and soybeans. They grow in pods, just like other legumes. Still, many of us think they are tree nuts like walnuts, almonds, or hazelnuts.
The double-slit experiment. Even when you slow the experiment down so that it's only a single photon, electron, etc. being measured you still see the interference pattern. Unless you put your detector behind the slits, then it's a solid set of two lines behind the slits.
It's almost like the universe is rendering itself differently based on observation.
Yes, but how? How do the photons receive the data that an observer is involved? Not even a sentient observer but a mechanical detector? A bunch of material parts like all the other material parts in the room including the slits themselves, yet these parts are recognised as being in the process of active observation? Something is passing between the 2 objects we can't see and the random is being altered to a specific set movement as a result. It's almost like there is actual code involved.
Load More Replies...If you understand the double slit experiment then you understand quantum mechanics. But that's all right because nobody understands the double slit experiment. I don't understand how a photon or electron can pass through negative infinite time (before the big bang) on its path between the slits and the screen.
This is where reality is a computer simulation conspiracy theory comes from. In a video game with a 3d layout, the computer only renders the areas in your field of view (lets say 1/4). The other areas outside of view exist as calculations only and can be inaccurate. So only when you look at those areas do the inaccuracies have to be resolved and a picture presented. Thus when not observed the computer would say the light through a double slit could be here or there, but when observed it has to be here.

Even if we were, what would that mean? There would still be a universe outside the sim and it wouldn't make any more sense than this one. Is the universe outside infinite or finite? How could it be either? Is it timeless or does it have a beginning and an end? How is either possible? What created it? What is the source of it's universal constants? Oh damn... being in a sim answers absolutely nothing!
Load More Replies...In Star Trek TNG they have the "Heisenberg compensators" in the transporter because of this.
The description of the result for a single photon is incorrect. The number of lines in the interference pattern and their widths depends on the width of the slits and the distance between them. In all cases, the lines in the pattern are brightest at the center and fade as you go out. For the single photon case, only a single photon is detected, but its position will be on one of the lines, and the brightest lines are where is it is most likely to appear. Conservation of momentum and energy demands that only one photon will be detected. If you shine a beam onto the slits, the pattern of lines output is the sum of lots of individual single photon cases.The last line describing putting the "detector behind the slits" really means that the detector is pushed up against the slits. Then you simple see the images of the two slits. However, that is still the same quantum result; the waves just haven't much space to interfere.
the double slit experiment blew my mind and makes me believe that all times and realities are happening simultaneously. we just can't see it because of our limited senses.
Apparently schizophrenia can hit anyone at any time, and using psychoactive d***s (like LSD and magic mushrooms) significantly increase the chances of you getting schizophrenia. To keep a long story short, it isn't a stretch to say that most religious and philosophical figures of our past were probably schizophrenic since many religions and metaphysical questions before science were based on visions, voices, and generic "signs" of whatever sparked their tirades. Makes me wonder a lot about how reality and unreality are just a matter of perception.
Psychedelic d***s do not cause schizophrenia, but they can be a trigger for people who are already predisposed to the disease, and it's not something that can "happen at any time" it presents sometime between mid 20's to mid 30's, with anything below 18 being classified as "early onset" and being extremely rare. Schizophrenia runs in families, there is a genetic component there, though it's not a single gene, it's some combination of genes that we've yet to identify. If you have zero family history of the disease, it's very, very unlikely that you're going to suddenly come down with it because you smoked a joint or dropped some acid.
SciShow about bad trips. Haven't watched it yet though. https://youtu.be/wmwMhuMpN_4
Schizophrenics are also naturally prone to marijuana use before diagnosis because it helps them through self medication even though THC is also psychoactive but not in the way LSD is Psycshoacrive.
If the hallucinations in schizophrenia consist of metaphors seen as concrete things, then those things might be very important and necessary to understand— which does not necessarily mean treating them as concrete objects.
I totally disagree, functional and psilocybin mushrooms repair and build neurological pathways and even more. Sounds to me like weed as a gateway, but opium is Dr Supplied so its good
Yes actually, that would be a stretch. I'm not sure the author knows what schizophrenia is. Unscientific interpretations of reality does not equal schizophrenia.
Most everything is made up of nothing. The distance between the nucleus of an atom and the electron is insanely large.
If the nucleus were a ping pong ball, the electron would be about 2 mi away.
that concept f****d up my chemistry grade. nobody could explain to me why it's "nothing" and not vacuum or sth. unknown. I was so hung up on it I couldn't concentrate on anything else...that was when I decided it was not nothing but cola..just so that topic was solved for my brain. Just imagine a world where every nook is filled with soda pop
Well it's not really nothing. We've done experiments that show that there's always little *blurps* of quantum energy even in the most isolated environments. It's part of the Heisenberg uncertainty principle.
Load More Replies...Not exactly true. The electron doesn't orbit the nucleus at some set distance. It's more like an electron cloud, where the electrons exist not as a particle, but as a set of potential states
The study of chemistry should always start with a study of wave interference. Particles are like some cheap parlor trick. Electrons *are* their wave function (orbital) and wave interference explains their bonding behavior.

Broccoli might seem like a totally natural veggie that many of us might love or hate, but it actually has an interesting backstory. It’s a result of farmers tinkering with wild cabbage, also known as wild mustard, for centuries! The original wild mustard plant had edible parts, but they were pretty bitter.
So, farmers started picking and planting seeds from plants with traits they liked more, slowly creating what we now know as broccoli. This process is called selective breeding, where humans step in to guide how a plant evolves over time. So, broccoli wasn’t just found growing in the wild—it was carefully developed over hundreds of years!

It is literally impossible to describe, in words, what quantum superposition is. Everything you've heard about quantum superposition is, at best, "sort of right" but also "alot wrong" but we *don't have a way to describe it properly* so those half-assed (schrodinger's cat, both and neither at the same time, etc) 'explanations' just stick around because without understanding the math you just can't understand quantum superposition properly.
Quantum reality is simply that different from macroscopic reality. Our intuition cannot comprehend what is happening. I do not understand quantum superposition, and unless you're a theoretical quantum physicist neither do you. And some of them don't!
But we *know* it's real. It happens. It affects reality. We cannot convey what is happening with words. That f***s with me so hard.
I think that’s as much a failure of language as understanding. No human language has the right grammar to describe quantum superposition in a non-paradoxical manner. Human language is based on our macro-scale perceptions, and is full of assumptions about how things work that are true only above quantum scale. Even the math can’t really tell you what it is, only how it works, because the meaning of the mathematical symbols and expressions is understood through the same filter of macroscale experience. If you can manage to think about it without trying to label things, you *might* be able to come close to a fuller understanding, but thought free of language in a mind that has language is a difficult skill to master.
"No human language has the right grammar to describe quantum superposition in a non-paradoxical manner." Actually, in Spanish we say "No tengo nada" (I don't have nothing) and it's correct. 😅
Load More Replies...That's what was so odd in quantum physics. Not just superposition but many things were described by models for *this* part of the curve and a different model for *that* part of the curve that led me to the belief I haven't yet shaken that no on really knows what's really behind it or we could find a way to model the whole thing.
And it is the reason for your intelligence. Quantum entanglement is why "you"exist.
Quantum superposition is just waves in all different positions possible creating new waves in the process until observed which fixes there position. Like an electron is a wave and a particle in the double slit experiment inglés observed make it one or the other in a fix position. It’s not hard. It means a possible positions a thing is in until the act of observation.

I learned that lobsters can theoretically live forever, and now I’m questioning why we’re not all trying to unlock the secret to lobster immortality.
Lobsters cannot. They have longevity due to telomerase repairing DNA telomeres, but eventually they lose the ability to moult due to old age, and their own exoskeleton crushes them. That is if their own moulting doesn't kill them first.
There are jellyfish that upon reaching a near death state will shed their bodies and emerge as a polyp again essentially restarting their life cycle.
please tell me that there are a group of lobsters running around with swords trying to take each others' heads off? "there can be only one!"

Great, now I'm hungry for lobster. Imagine if consuming the creatures is the secret to unlocking that extreme longevity, though!
In fact, we all should be able to live forever. Science has only partially understood why cells stop replicating.
Crocodiles do not die of old age. They will just keep getting bigger and older until they die of some illness or accident. Several crocs in captivity are well over 100 years old.
Claimed to be. We cannot determine age on crocodiles very well, and the claims are all on Crocodylus porosus. The average lifespan of C. porosus is estimated at 90 years, so of course there will be older. They do die of old age, old age is just different for different crocodile species.

One fact that often blows people’s minds is that the universe is constantly expanding.
If you really want your mind blown…. The universe is constantly expanding… into what? Into nothing you may say. But if it is nothing then you can’t expand into nothing because there is nothing to expand into…. And now my nose is bleeding.
Yeah they say as the universe expands it creates the space with it to expand. I've also heard the multiple universe theory, that although it's impossible to travel through nothing, there is probably more than one finite universe. Possible shaped like globes as the gravity is created by the masses that make up the universe, just like how planets form. I feel like Isaac Asimov would say that we won't know until we evolve beyond anything corporeal, and exist as pure energy, but beyond any type of energy we can conceptualize now. Then *maybe* we can learn the secrets. So, if humans don't wipe ourselves out, or some complete extinction event happens, (unlikely-more likely there will be many many extinction events and other species will take over and reach higher technologies etc, but then they'll get wiped out), for like millions of years, then someone will one day know. Doubt it. But a cool idea!
Load More Replies...The one that most people, including most physics and astronomers, find most difficult to understand is that, the local universe does have a velocity. The metric of special relativity is not the metric of the expanding universe. The universe does have a preferred reference frame.
This velocity is easily measured as the dipole of the cosmic microwave background.
Load More Replies...And according to the same theory (math, and with all observable/non-observable evidence) there is literally *nothing* beyond it the edge of the universe.

I remember watching a video on how the universe might end. It was a 30-minute time lapse of what occurs from the Big Bang to the "end."

No one knows what the markets will do tomorrow, but some people like to imagine they can calculate the final course of the entire cosmos over trillions of years. Yeah... get real. The heat death argument is like saying the Mayan calendar predicts the end of the world.
Human comprehension of reality is so far from accurate its functionally useless. Every understanding, scientific discover, whatever we make, is at BEST just us trying to make things make sense to us. But humans simply don't have the brainpower/hardware to come anywhere close to an actual understanding of reality.
It's like an ant walking on an iphone. Its brain can process things like "this surface is smooth" "there is no food here" and thats about as complex as it can get, but that's nowhere near the level of complexity of the iphone itself.
The scientific method tries to explain how something works, then revise the explanation when new information proves the previous explanation is wrong. Repeat as often as new information comes in. The scientific method is useful, because even though we don't know everything, once we know enough we can use the knowledge for making things or avoiding things.
It may be lacking understanding, but it's far from functionally useless. Our limited understanding feeds us, saves lives, explores our world, etc etc. Even the ant example matters to the ant -- it doesn't comprehend the iPhone, but it interacts with it as much as it needs to. It is amazing to contemplate how little humans can comprehend, but our brains are not functionally useless.

We're getting very close with actual experiments being able to capture and measure some of the the most fundamental concepts of reality right now. If we can measure a certain type of neutrino decay we will have the data on how matter came into existence. Once we build a functioning nuclear clock (not an atomic one) which we have the knowledge for right now; we will be able to test many universal constants in physics.
But that's the point of it. The first step is, to try making sense for yourself. The next step is, to understand that is more complex, what you can now discover. And from there comes the possibility, that some day you may uinderstand the whole picture.

Load More Replies... "The Birthday Paradox" is a fun one. I wouldn't say I "questioned reality" as I am math nerd, but it's fun to share with people who aren't so inclined.
For those unaware, it deals with the probability of two randomly chosen people out of a larger group of people having the same birthday, and that you only need a room of 23 people for that probability to be greater than 50%. 50 people and it becomes 97%.
To explain a little further on why this ends up seeming so surprising/impossible for most people when they first hear this, it's because people often confuse the premise of "probability that 2 randomly chosen people share a birthday" with "probability that 1 other randomly chosen person shares MY birthday", which is not the same calculation.
For example, there have been 45 United States Presidents. Two of them share a birthday (November 2): James Knox Polk (born 1795) and Warren Harding (born 1865).
I share a day/month/year birthday with Pres. Clinton. I like to think that a really bizarre twist of fate may have resulted in me living now in a mansion in the US & him in a retirement village in Australia - or something like that!
Load More Replies...I'm a teacher with 22 students. I have three pairs of children in my class this year that share birthdays.
And then there are some of us weirdos that manage to have two (or more) kids on the same day years apart. My oldest and my youngest share the same birthday 14 years apart. My oldest called it too.
It also has to with distribution. It’s not 1:365 as a chance to be born. More people are born in September than any other month and more people are born on September 9th than any other date. There 1:365 are not your odds of being born on any day. The law of large numbers doesn’t apply in this scenario. And the birthday paradox is a fascinating known math funsy.
I personally know two people who have the same birthday as me (different years though), and know of a couple of famous people.
If you had a really long stick that connected to the Moon, and you pulled the stick, the other end of the stick wouldn’t move instantly. It would take as long as it takes for the speed of sound travelling through wood to reach the Moon from Earth for the other end to move as a result of your pulling the stick
I think the thing that gets me about this is I knew everything I needed to know to reach this conclusion on my own but I’d literally just never thought about this specific hypothetical before, and when you actually write it out like that it feels so counterintuitive even though I intellectually understand all the component pieces that make it true.
I don’t understand this. If I’m holding a piece of spaghetti and I pull it, the other end moves instantly. Why would the end of a crazy-long piece of spaghetti that reaches the moon not do the same? Am I stretching it out when I yank?
This does remind me that if you hold one end of a slinky so that the slinky is hanging in front of you, and then let of it, the bottom will come up slightly while the top is falling.
But the stick would never be attached in that manner as the moon orbit would snap the stick instantly
Light doesn't experience time. From its departure from a quasar on the far end of the universe to a sensor on a space telescope that was built a decade ago, the journey took almost the entire lifespan of existence.
And yet, as far as the photon is concerned, the trip was instantaneous.
If that wasn't wild enough, here's the real mindf***: There's no such thing as a free photon. They only exist as a carrier for energy exchange between electrons. For a photon to exist it has to have a sender and a recipient. Two electrons separated by the entirety of space and time somehow agreed to exchange a photon.
I remember reading once a hypothesis that, because an electron doesn't experience time, that all the matter and energy in the universe may consist of a single electron.

When measuring a coastline, the smaller the unit of measurement, the longer it is.
It's not about the units, it's about how many details you measure. On a large scale, you brush over the little crevices and bays so the total distance is shorter. The more detailed you measure, the more "left and right" you measure instead of a straight line, making the total length longer..
Same thing, different way of stating it. The size of the units you use determines the amount of detail you can measure, and the amount of detail you want to measure determines the size of units you need to use. The two are inextricably tied together.

The other problem is that a foreign -government- owns a possibly controlling interest in part of our public infrastructure. Every aspect of this deal is bad, and the whole thing should be illegal.

I read once that the arrangements of molecules or cells or atoms (i really can recall what precisely) looks eerie similar to the way galaxies and clusters look.
This made me think that perhaps our universe is just a sumatomic thing within something larger, like a fly in a cats a*s.
Image that!
I don't wanna ... I mean the fly and cat butt thing .. my imagination would be a bit different. But I get it.
It's only the conventional drawings of electrons orbiting around a nucleus that gives this impression. Electrons don't actually orbit like a moon around a planet, it's a lot more complex, and science uses probabilities to determine locations of electrons. https://www.geeksforgeeks.org/shapes-of-atomic-orbitals/
I hesitate to take science advice from someone who types so incomprehensibly...
Galaxies, cells, lilies, lava, you're looking at liquids and solid structures flowing.
It's hard to explain, but the universe follows a law of symmetries - A lot of things are comparable no matter their size because they share the same symmetry. (Very interesting topic)
Just learned today that if a photon enters a cloud of atoms that are cold it can leave that cloud before it enters.
negative time.
[https://www.newscientist.com/article/2448067-light-has-been-seen-leaving-an-atom-cloud-before-it-entered/](https://www.newscientist.com/article/2448067-light-has-been-seen-leaving-an-atom-cloud-before-it-entered/).
And a photon never has to pay for extra baggage... because it's traveling light.
I think people get confused because they've heard repeatedly that the speed of light is a constant, c. But that is light's speed in a vacuum. In other media its speed can vary. Think of a prism; it separates the wavelengths of light because they travel different distances through the glass and are therefore slowed down by different amounts.
Time dilation.
Brian May wrote and sang the song '39' about time dilation. It appears on Queen's album "A Night at the Opera", the same album that has Bohemian Rhapsody if anyone's interested.
Time dilation exists in the individual's experience. The older you are, the closer the days, weeks, months and years get together.
Time dilation is my specialty however explains it in the most simplest of terms Can be frustrating if the recipient has not even the most basic knowledge of physics or relativity. They don’t get that gravity is strongest at the surface of mass not the center (there’s no gravity at the center of the earth), acceleration and gravity are the same thing, gravity and acceleration both will slow time for one person relative to another observer at rest or lower gravity. At 99% the speed of light one stationary observer ages 36 years while the one in motion ages one. Time travel forward has always been possible but will be possible to travel backwards in a closed system like ours or clearly it would have happens already. And on and on.
Not to be confused with time dilution. (Which I’m not even sure how one would define, but it sounds neat.)
Rock beats scissors. Sure, I get it.
Scissors beats paper. Again, makes sense.
Paper beats rock. WHAT? That's some serious *we live in a simulation* situation.
Scissors cuts Paper - Paper covers Rock - Rock crushes Lizard - Lizard poisons Spock - Spock smashes Scissors - Scissors decapitates Lizard - Lizard eats Paper - Paper disproves Spock - Spock vaporizes Rock - (and as it always has) Rock crushes Scissors
I prefer Foot, Cockroach and Nuclear Bomb - Foot > Roach / Nuke > Foot / Roach > Nuke
The way I was taught: Rock beats (ie damages) scissor. Scissor cuts paper. Paper covers rock.
What is reality without any mind to see? Is it just atoms and electrons? What are the characteristics of these "ultimates" with no mind?
I assure you that reality cares not for our perceptions. The universe did not begin with us.
"If you examine your mind with your mind, how can you avoid confusion?" - Buddhist saying
This is just an over-complex version of "a tree falls in a forest". If we are not here to witness any of this, does it even exist?
What are your own impressions right now? There are so many things around us that our brains can't handle it - so stuff gets filltered and our brains fill in the blank spots to create a continuously state of consciousness
That UFOs/UAPs are acknowledged by the US government and Congress is currently debating legislation about whether or not to declassify information related to them that has been kept hidden by top secret defense programs since 1947. All of this being spurred by multiple whistleblowers (whose information was recently leaked by the inspector general's office) making astonishing claims under oath before Congress such as exotic (not of this Earth) materials being in the possession of defense contractors and even more incredibly that non-human biological material has been recovered from crashed UAP.
All of it seems unbelievable and very well might be complete nonsense, but the attitude of our elected officials who have been privy to more info than us screams to me that there's more to it all.
https://youtu.be/NB1oTeTOgHw?si=bs5r85-38lcBGgsZ.
UFOs/UAPs are fancy acronyms that mean nothing more than “something was seen in the sky that those observing it could not identify.” Once identified, the “U” is no longer true. So of course they’re acknowledged: not knowing what it is doesn’t invalidate the fact that you saw something.
Exactly. I saw a "UFO" about 30 years ago. Driving in a mountainous area late at night, I saw an object with lights move across the sky. I call it a UFO because I couldn't identify it; not because I think it had anything to do with aliens.
Load More Replies...UFOs are not signs of aliens visiting the Earth. There is literally zero evidence to suggest that any of them have "crashed". The elected officials are not hiding anything about them because there is nothing to hide. There is a shedload of other secret military stuff which is quite justifiably hidden from the public and much of the information you refer to may very well contain genuine military or scientific secrets. Just not any about alien life.
The fact that we have not been contacted by intelligent life is the most conclusive argument for its existence.
The logic of "we can't possibly be alone" is seriously flawed. If you look at the special conditions that made earth into a life-producing planet, combinations of the single very large moon producing tides, the distance from the sun, the slight wobble giving us winter and summer seasons... it is actually entirely possible that even in the vastness of the universe those exact combinations have never come together to produce life and allow it to flourish and develop as has happened here.

That there is no such thing as a fish.

Load More Replies...Sounds like a troll, or someone that doesn't belive there are penguins either..
Load More Replies...The problem with this and all the other posts with "facts" is there's rarely any evidence to support they are actually, true and real.
Load More Replies...Not true. Fish is a term used to cover multiple clades that live in water. It was long assumed they all came from the same source species, but it now appears not, just that they followed a similar path, and have a resemblance.
Oysters are classed as shellfish (literally fish with shells) but bear no resemblance to eels. Calling an animal a fish tells us nothing about the animal except that it lives in water, so 'fish' as a descriptor is useless.
Load More Replies...Yes! I loved this realisation. It made me appreciate marine wildlife so much more
.'Fish' is just an arbitrary umbrella term for many diverse species with little in common. A lobster, grouped in with crabs, shrimp, etc. as a shellfish, has little in common with a cod, which has a skeleton made of bones, which itself is different from a shark that has no true bones but instead has a cartilaginous skeleton. Basically, calling an animal a fish tells us nothing at all about the animal except that it lives in water, but then so do some mammals and arachnids, but we don't call them fish.
If you craft your definition to that purpose, there's no such thing as no such thing.
But there is an amazing podcast of interesting facts called "No Such Thing as a Fish"! Well worth a listen!
It may be the case that the universe goes on forever in all directions and it's all just as full of galaxies as what we see around us and that there is no center.
There are infinite Shakespeares and one of them wrote a play about monkeys. He called it Monkbeth.
That could be literally true.
Well, you're right and wrong at the same time. In a sense, yes, universe goes on forever and has no end and no center - that's the theory. At the same time, the same theory supposes that there was a beginning and it resembled an explosion that pushed matter (I'm using that word very loosely) equally in all directions. That would indicate there should be a center from which the universe is expanding. And possibly an end - the ever moving edge of that initial flow, wave of matter expelled from the bang. The thing is, nearly everything we know about those topics is a theory - the best assumption we can make with the best knowledge we have. And there's just so much we don't know and understand, that it can't be even quantified.
Oh, and there are no infinite Shakespeares. That's common misconception strumming from confusing possibility and probability. It's possible that there is another Shakespeare. But it probably isn't.

Not true according to rabbit owners that discuss the same thing in another post in boredpanda. They say rabbits have toe beans but covered in fur, doesnt mean they dont have one. Some even say their rabbits toe beans exposed and not covered by any fur at all.
“Toe beans” are another word for paw pads. Rabbits don’t have paw pads. “Bunnies do not have paw pads because their feet were built for strength and durability rather than speed. Instead, a rabbit's feet are cushioned and protected by a layer of thick fur.” There are no paw pads underneath because fur doesn’t grow on paw pads.

In your car, you can reach from the driver seat to the passenger door (might have to lean.) You cannot however be on the left hand side of a bus and reach across and touch the right hand side of the bus. But both vehicles fit in a single lane on the road.
You apparently never owned a 1969 Cadillac deVille or a 1965 Chrysler Imperial. I am 6'1" and I can not POSSIBLY reach the passenger door from behind the wheel.
I’ve driven many cars too wide to reach the passenger door from the driver’s seat.
There's 10+ years of peer-reviewed science on pre-cognition (seeing the future) that is replicable, and anyone can learn to do it.
Every day I preconceive that I will read at least one dumb thing. Here it is.
lol what utter horseshit. The US government (along with others, Russia comes to mind) have been playing this game off and on since the 50's. MKULTRA and the use of LSD played into the "study" of precognition/telepathy/Astral Projection/ Telekinesis, and while there have been many claims of "positive findings" in reality the results boil down to being little better than guesses with a very heavy dose of confirmation bias. "The subject was able to correctly predict ______ over 50 times during testing, it's a success!" Yeah numb nuts, along with how many hundreds of failures? An uninformed observer could watch someone crushing it at blackjack and assume that they must have "the eye" or some other such nonsense, because they don't understand how card counting works. That you fail to understand how something is done doesn't mean you can reduce it to "magic" or "superpowers"
Experiemtns have shown that it's a 3 second estimation at best though
Look up Joe McMoneagle, Ingo Swann and Pat Price. There is even CIA documents that say it is real.
The CIA funded experiments; they didn't say it was real. A quick look at those three. McMoneagle claims to have remote viewed the origin of humans, who he said came from creatures like sea otters rather than primates and were created in a laboratory by creators who "seeded" the earth and then departed. Ingo Swann and Price were Scientologists, which immediately calls their credibility into question. Swann 'remote viewed' Jupiter and described mountains, a sandy, quartz-like surface and running water and missed seeing any of its 95 moons. He later re-interpreted his 'visit' to better conform with the findings of NASA's Voyager discoveries. The CIA's assessment of Price was basically 'sincere but delusional'.

Also money is fake and monarchies invented it to prevent getting overthrown by people who owned less land or no land. Stop pretending money and social class are real; at this point we're just polishing our chains in front of each other.
Money is an invention for you to ease your everyday life. So, you won't need to carry with you 2 goats, 5 chickens and 4 turkeys to exchange them for a sword and shield.
Damn, where do you buy your swords & shields at that low a price?
Load More Replies...Money is a medium of exchange and a way to quantify value. It may have no “real” existence, but its utility as a functional concept is invaluable.
The earliest form of a unified currency were sea shells used by tribes living on islands in the pacific, so are sea shells fake too?
If you had tried to argue this on the basis of Fiat currency (not backed by precious metal or other commodity), you might have had a bit of a point. But....money, was developed to prevent people from having to haul around heavy metal, livestock or other cumbersome goods so as to be able to engage in commerce. Saying money is "fake" is like saying "laws are made up" Yeah, they are....but the fact that if not everyone, than at the very least of majority of people acknowledge, agrees with or at the very least engages with the system is what gives it power. YOU can think and feel and believe that it's meaningless all you want....you'll just be prevented from acquiring anything of significant substance outside of whatever dirty little commune you call home. Money represents how other value your skills, talent or knowledge. It's understandable that some people don't like this fact, but....it also really doesn't matter.
