Infrared light was discovered all the way back in 1800. By accident. With a thermometer.
William Herschel (who also discovered Uranus) was experimenting with a prism. He wanted to see if different colors of light had different temperatures. So he had the room completely dark except a beam of light hitting a prism and casting a rainbow onto the table. He had placed thermometers in each color band to see if there was a difference. As a control, he had an additional thermometer past the ene of the light below the red band.
Except when he compared his readings he got something strange: the control thermometer was reading the highest temperature of all. This didn't make any sense. Was his thermometer faulty? He tried a few more tests with more thermometers in other places and came to an inescapable conclusion: there must be an additional invisible "color" below red that carried more heat than any of the visible colors. He named it infrared, which just literally means "below red".
Discover infrared, meh, discover Uranus humor for mankind, brilliance and acclaim

There was a period of about 50 Million years when we had trees on earth but nothing to decompose dead ones, so they just piled up, and up, deeper and deeper, they got buried and eventually we got coal!
The Carboniferous period was when trees grew tall, but had shallow roots, and fell over. Trees landed on trees. There was no microbes capable to digesting cellulous of lignin. The trees turned into peat, and then into coal. It wasn't until the lignin and cellulose microbes evolved that trees started becoming compost.
This is not "100% True"... It is one theory but is not agreed upon as "fact". I'm a microbiologist and I'm in the camp that believes it's highly improbable that neither bacteria nor fungi had the means to breakdown plant matter not to mention plant matter isn't the only thing that makes up coal. Coal is heated and compressed carbon, and not all organic matter is/was trees. I am not a paleomicrobiologist nor a paleobotanist and didn't study this extensively, but it's my humble opinion that this one can't be called "100%True"... here's a god short read on the topic though (which is newer than the article that first claimed that this was how coal was formed during the Carboniferous period.) https://www.discovermagazine.com/planet-earth/how-ancient-forests-formed-coal-and-fueled-life-as-we-know-it
Sad to think that dead trees are eventually a source of killing live trees because we burn up so much coal the air gets toxic.
That is worrying, since from this explanation it follows that as we now do have those microbes, no further coal will be created. Ever.
i would assume soil, wind and rain, and maybe other plants contributed
Load More Replies...This may not be true. There is evidence that lignin-decomposing fungi existed at this time. The alternative is was just because there were vast swamps at the time, and peat accumulates at the bottom of swamps because the acidic, oxygen-poor water there slows down decomposition. https://arstechnica.com/science/2016/01/why-was-most-of-the-earths-coal-made-all-at-once/
Correct. It would simply decompose via microbes.
Load More Replies...The Reddit user really got the ball rolling when they asked the community members what is a cool scientific fact that they know that sounds unbelievable. “I am always interested in learning about cool new facts and what better place than Reddit to ask this question!” they told Bored Panda.
Their question attracted roughly 3,000 comments, which must have provided plenty of information for them to get acquainted with. The answers from other redditors covered all sorts of fields, from chemistry to geology and everything in between. The OP, who is a mechanical engineer themselves, said that they have always been fascinated by physics and the universe.
They also revealed which scientific fact blew their mind the most: “The fact that I love the most and like sharing with people is that the human brain named itself! Given enough time, hydrogen starts to wonder where it came from!”
30-50% of people don’t have an internal monologue.
I simply cannot fathom this, Even in the most dire of personality disorders. How could one prepare important , well anything or review correct personal behaviour. I'm not doubting, just feeling genuine confusion regarding this
I have no idea how an internal monologue would be necessary for that. I don't have one, and I can still reflect, it just isn't narrated.
Load More Replies...You know those people we're all jealous of who can go to sleep within a minute of shutting their eyes? It's them lol.
Yes 😆 my partner has no internal monologue, doesn’t think too much and can fall asleep within two minutes, it’s mind blowing and baffling to me
Load More Replies...What? How? Who are these people? Don’t mind my comment, just talking to myself.
with everyone it must be different, but for me, it's not actually silence. Usually there's stuff there, a feeling, a song, a few words, just not full blown sentences and arguments. Or maybe I do have an internal monologue and just don't think much lol
Load More Replies...That must be those people who chatter all the time and can't just shut up for a moment
As a chatterbox, I can very well assure you that I have an inner monologue
Load More Replies...I'm one of those people. I only found out this wasn't considered 'normal' until quite late in life. My friends simply don't understand what it must be like. It's hard to describe to other people. You just sort of absorb things and work intuitively. If I wanted to have an internal discussion with myself- for example to weigh up options before making a decision- I actually have to vocalise it. Honestly, I have to pretend I'm talking- out loud- to another person in order to do that. Apparently people have that other voice in their heads all the time!
You just described my experience beautifully!: " If I wanted to have an internal discussion with myself- for example to weigh up options before making a decision- I actually have to vocalise it. Honestly, I have to pretend I'm talking- out loud- to another person in order to do that." It blows my mind that this isn't considered normal. The alternative sounds chaotic and stressful to me, but it does explain why I like to process things out loud with other people.
Load More Replies...As a default, I don't have an internal monologue, but I can turn it on if I want or need it.
I don't buy this. Never have. Can anyone say that they don't or know someone who can the say that?!? I don't!!!
I don't have an internal monologue. My thoughts are images, feelings, smells, sounds... I can turn the monologue on, mostly, if I want to, but if I don't make a conscious decision to have it, it's not there.

The largest organism in the world is a massive underground network of mushrooms.
Possibly. I learned this fact on that Netflix documentary "Fantastic Fungi" (it IS fantastic, highly recommended!!), and when I saw it on Last of Us, I was quite proud of my trivial knowledge lol.
Load More Replies...The mycelium network actually makes us travel throughout the universe in seconds if we have a spur drive. I saw it on Star Trek so it must be science. There's nothing more sciency than Star Trek
If you eat certain mushrooms, you too can travel through the universe from the comfort of your bedroom.
Load More Replies...It helps the forest communicate by sending distress signals to other trees when one is under attack from pests. The trees then send nutrients using the mushys to help counter the pests damage
I thought that the Pando Forest was the largest organism..? I do know that it is shrinking however, due to human activities and drout 😕
Giraffes’ tongues are black and purple to prevent sunburn while they’re feeding up high.
I knew if the colors but not the purpose! We can feed giraffes at our zoo and I love to watch how they curl their tongue around the food!
Yes. Love the giraffes myself <3 Also am envious of their tongues. Could have made a lot more money in my life in a different industry.
Load More Replies...I was once kissed by a giraffe, and can attest to this tongue fact. They also have drool with a very thick viscosity.
The closest relative to the giraffe is the okapi. After that, you have to cross over to North America and look at a pronghorn to find the only other close relative. The three are the only modern representatives of the super-family Giraffoidea.
Sharks pre-date trees
Also: there were no grasslands when there were dinosaurs. Only deserts and forests, swamps, etc. Plants normally die of a lack of carbon dioxide. To get enough CO2 to survive, they have to hold their pores open in the daytime, when they can unfortunately act fantastically efficiently to dry up the plant. Grasses have a secret weapon, c4 metabolism: they can capture the sun's energy in the daytime by building high-energy carbon bonds. This does not make more carbon, and therefore does not provide food or growth. But it does mean that c4 plants can wait until it is dark to capture that carbon and complete the photosynthesis in the dark. Global warming would allow insects, cold-blooded animals, etc., to reclaim their advantages over mammals which can keep their body temperatures warm themselves. That kinda sucks being a mammal. But it would not cause desertification; just the oppsite: deserts form when the Earth is cool and has low carbon levels.
Sharks are MILLIONS of years old. You would have thought humans had learnt not to fear them, but I guess not.
Show me one shark that's even one million years old!

Load More Replies...Soap works simply because it makes water **more wet**. Soap breaks surface tension, easing water's ability to get into cracks and crevices, to wash away dirt deposits.
For dirt, yes. But soap also kills bacteria by disrupting the lipid layer of the cell membranes. This is why you don't need to use "antibacterial soap". Soap is already antibacterial. Antibacterial soaps and hand sanitizers kill bacteria with poison, which bacteria can develop resistance to. This is why it's better to use non-antibacterial soap, which bacteria cannot build up resistance to. Antibacterial soap is contributing to the development of "superbugs"--bacteria (and viruses) resistant to antibiotics. Sadface.
Also breaks the lipid layer of a virus. So I don't know why the antibacterial stuff is pushed so much.
Load More Replies...If you want a slightly more "ick" version of the same, the slimy feeling if you get bleach on your hands is from hydrolysed skin cells, i.e. the bleach turns a small amount of your skin to soap.
Not quite accurate. Soap works because it's a surfactant, i.e. it's a substance that draws other particles/substances onto its surface.
Seriously, I'm like no, it's a surfactant...
Load More Replies...Well, not entirely. I believe it also reacts directly with both hydrophobic and hydrophilic compounds in the “dirt”.
But soap smells good and has other ingredients so I don't agree completely.
Soap does work everything but not simply. Soap molecules have on one end what’s known as a polar salt, which is hydrophilic, or attracted to water. The other end of the molecule is a nonpolar chain of fatty acids or hydrocarbons, which is hydrophobic—meaning that it’s repelled by water but attracted to grease and other oily substances. In other words, it makes lipids (fats) soluble in water. Also it washes off lipid bacterial membranes thereby killing them.
and stops the dislodged sticky dirt from sticking back onto your skin.
Also detergents wrap grease molecules up, stops them sticking and lets them be washed away in water.
There's a small chance that, if you were to slap your hand on a table, all the molecules in your hand would miss the table and go right through it. The odds are *astronomically* tiny, but not zero.
*slaps again in frustration* missed again! Proceed to get more and more angry
Load More Replies...That just changes the odds, if you had a piece of paper, you are more likely to go through it than an inch of hard wood.
Load More Replies...They've already built a slapping machine to figure out how many slaps it takes to cook a chicken. Time to upscale that machine to test quantum tunneling probabilities. (═
I had a cat when I was kid that was determined to prove this. He would randomly and repeatedly walk into walls, bonk his head, then move off and try a different wall. He had no vision or coordination problems and was otherwise perfectly healthy, so we figured he was just testing physics.
For some reason, this makes me think of the experiment where you see how many slaps it would take to cook a chicken. There are many YouTube videos, but I would love to see one where the hand goes through the chicken...
Magnolias predate bees and were first pollinated by beetles and earlier bug species.
We had a tornado hit our area pretty bad in December 2021, tons of trees uprooted completely and damaged. so a lot of us got tree vouchers for $200. We were able to get two star magnolia and two Jane magnolia and planted them in the front yard. They’re blooming now! They’re beautiful.
Even the ones made out of steel? (backs slowly out door then runs away)

Load More Replies...I read “Mongolians” first and was very confused there for a minute🤣
I just learnt recently about a scarab beetle in aus that pollinates flowers, a fiddler beetle, very kool looking and lime* green stripes etc. I found a dead one and asked an entomology group on fb
The immune system does not encounter viruses and formulate an antibody that matches its shape. Instead, the immune system pumps out random antibodies that sometimes happen to match a virus it comes into contact with, and then begins to produce more of that specific antibody.
Also, viruses are not alive according to our understanding of life. They are inanimate complex organic matter. They lack any form of energy, carbon metabolism, and cannot replicate or evolve. Viruses are reproduced and evolve only within cells.
There appears to be ongoing debate about whether viruses are living. I'm not knowledgeable enough about the subject to debate the matter, so I'm going with "don't know" for now.

Water IS actually blueish-greenish in color. It's just a very very weak tint, so it usually appears simply transparent (and reflecfing the color of stuff around and inside it). But when it's in very large volume, in a perfectly white room, under perfectlu white light, the water's very own teal colour becomes visible.
Similarily, the sun seems goldish-orange from Earth due to the atmosphere. The light of the Sun itself is mostly white. However, if we were to analise the light very accurately, it's actually a very subtle pale greenish/lime. We still see it as plain white in space, but I just think it's so cool.
Thank you for all these colourful facts, they really brightened my day I won’t li(m)e. I’m honestly green with envy I didn’t kn(yell)ow them sooner, so I wasn’t redy for them. And yes, I eill keep this going till I’m blue in the face, just you white and see. 😁
The sun's visible light output is most intense in the yellow-green part of the spectrum. We've adapted to see that as white and see only highly monochromatic greens as green because if we didn't, well, we'd have struggled to find food or avoid ambush predators in a habitat dominated by green to yellow foliage.
Incidentally, chlorophyll and the way it absorbs red and blue but not green light was probably an adaptation to make early unicellular photosynthetic life a couple billion years ago more robust to changing sunlight. The sun is brightest in green light, but it's also most variable in that wavelength range, and stars typically flare less with age on the main sequence (once they start up the giant branch, all bets are off).
Load More Replies...I’ve also been told that stars appear to twinkle only because of our atmosphere. The stars themselves aren’t changing at all but the light going through our atmosphere makes them appear to shimmer.
Correct. The stars probably are changing too (Betelgeuse is a roiling amorphous potato of a star because its giant phase is so advanced), we just can't usually resolve those changes unless they're variable stars. As an aside, the reason planets appear not to twinkle (usually) is because the angular sizes of the eddies in the atmosphere, which act like tons of little shifting lenses, are much larger than the angular sizes of stars, but usually smaller than the angular sizes of planets. For stars, the whole image can jump around and has different wavelengths of light focused in different places at different times, but for planets, the images coming through the atmospheric lenslets usually have some consistent overlap. (Having taught astronomy in FL, I can tell you that planets can twinkle if the atmosphere is bad enough, e.g. after a storm)
Load More Replies...I found corroborating evidence re: the color of water, but not for the sun being greenish. Has anyone found citations for this you're willing to share?
Here you go: https://eclipse2017.nasa.gov/what-color-sun Essentially, the sun emits most of its energy around 500 nm, which is close to blue-green light. So one might say that the sun is blue-green! The reason why the sun looks white to us is because our eyes see all of the light emitted by the sun, not just the majority (blue-green). Because though the sun emits strongest in the green part of the spectrum, it also emits strongly in all the visible colors – red through blue, making our eyes put the green, red, and blue parts of the light together in our vision. Hope this helps!
Load More Replies...this is mostly true. The sun's blackbody radiation is approximately in that area, but because the visible light is on a logarithmic scale, the light appears mostly white. (I think, i haven't looked it up recently pls correct if anything is false.
GPS tracking is not the satellites tracking the object, but the object tracking the satellites.
That‘s why it is Bulls**t in Movies when they say „Their car has GPS so we can find it“. No, you can‘t. There‘s no feedback.
You can have GPS trackers as an anti-theft measure, but I don't know how common they are in cars (more common in construction). It works the same way as a phone tracker, so the software pulls a GPS location and transmits it over LTE. You're about not being able to communicate via GPS though.
Load More Replies...Actually there is no « tracking » at all. The satellites send their signals in all directions and a receiver just calculates its own position from a few signals. It does not track satellites and the satellites don’t even know who is using the signals and where.
While the receiver doesn't actually track the satellites it is required to compute their position with the same accuracy as it computes it's own position.
Load More Replies...Isn’t this common knowledge? [Edit: Reading the comments, no! I bought one of those handheld Garmin GPS devices for my hiking. There was no subscription to pay, so therefore it was always obvious you didn't pay for satellites tracking your device. In the manual it also said a bit about how it worked. With a modern smartphone with built-in GPS it's probably less clear how this all works.]
Reminds me of the NES Light Gun. It reads the point of the TV screen it’s pointed at. The TV screen doesn’t read a shot from the gun.
Just about every car sold in the US within the last 20 years has GPS tracking in it's emergency response/telemetry. My 2007 pickup truck sends me an email when the tire pressure is low and would call 911 and give them my location if I were ever in an accident..
Some cars have that, some don't, and if you don't subscribe there will be no cellular service to communicate the information. My 2013 didn't have anything of the sort at least as standard. (I never looked at what was in the high upgrades.) When a woman didn't look I replaced it with a 2018, still no cellular in the trim I was looking at, I don't know about higher.

If you got sucked into a black whole, time would slow down too. Meaning while you are getting Spaghetiified, time is slowing down to the point where you will watch the universe die with you
Blackholes are super weird and interesting. They can literally bend spacetime and light which means that you can see every angle of the blackhole by staring at it and not moving
Of course most of this is theoretical. Astronomers only just confirmed the existence of a blackhole recently.
Load More Replies...Yep, it is. It occurs when the gravitational force on your legs is much stronger than the forces on your head so your legs get pulled away from your body which everntually becomes a stream that’s a few molecules wide

A serving of movie theater popcorn is equivalent to two Big Macs, in terms of calories, saturated fat, and sodium.
And perhaps why it costs the same...lol. I will never understand paying $8 for a bag of popcorn smh
Load More Replies...Not true. Unless you smother it in “butter”, oil popped popcorn isn’t really that bad for you.
Except theatres don't pop it in unsaturated vegetable oil, they use an oil with saturated fat because it's more stable and results in better texture for the popcorn. Theatre popcorn can't be compared to home popped popcorn.
Load More Replies...Why choose? Just have two Big Macs AND a serving of popcorn.
Load More Replies...Totally depends on how much popcorn grease ("butter") you put on it. But this also tells us ONCE AGAIN that Big Macs aren't that insanely unhealthy (even moreso if you leave off the "special sauce")
A Big Mac is actually almost twice the calories of a serving of movie theater popcorn. The entry is wrong.
Load More Replies...Whoaa, I just checked for the Netherlands: 1 bag of regular salted popcorn, no toppings or whatever, just mais, sunflower oil and salt is 538 Kcal per 100 grams (that is 1 bag). 1 (one!!_) Big Mac is 525 per portion (source: MacDonalds NL - Albert Heijn Chio gezouten popcorn)
You would have to eat 14 cups. Big Mac - 563, 7 cups AMC popcorn - 600.
That is what I wanted to know. How much popcorn, cooked in how much oil, with how much buttery topping on it?
Load More Replies...A Large Popcorn at an AMC theater is approximately 660 calories. A Big Mac is approximately 560 calories… so not double in terms of calories. Large Popcorn 31 g of Fat, Big Mac 32.7 g of fat, so not double fat. Large Popcorn (without added salt) 0 sodium, Big Mac 1g of sodium. Unless you drown it in butter and salt… the popcorn is roughly the equivalent of 1 Big Mac.
Scientifically: The odds of my girlfriend having the same key in our city (San Diego) turns out to 1:724,480 but it seems impossible. After a year of dating, turned out we have the same key to our individual apartments. (Different lock manufacturers)
I came out of a mall walked over to my truck, opened the door and started the motor before I realized this was not my truck. same green F150 and the same key it seems. I only realized it was not my truck when I saw the white snoopy stirring wheel cover that made me look at the rest of the inside to see stuff that was not mine.
My friend had the same car key as one of her teachers in high school so she would move his car to a different parking spot during lunch.

Reminds me of the counter intuitive answer to a math puzzle - how many people would you need to be in a room for the probability that any two people in the room share a birthday, to be more likely than not (eg over 50%). Answer: 23
My mom, dad, mom's friend, and dad's aunt all had the same birthday with my mom's friend being born the same year as my dad. The four of them were never in a room together but three of them were at various times. I have no idea what the probability of that is.
Load More Replies...My old apartment key worked to unlock my friend’s apartment, but hers didn’t work to unlock mine. It worked great for when I cat sat for her though!

Tried hers on mine and it didn’t work 🤷♀️)
My backdoor key opens the front door but the front one doesn't open the backdoor
How did you find out those odds? I have TWICE found cars with my same key. One time, I found one which looks identical to mine (same make, model, color, trim) and was driving off before I started to ask myself what all this other person's stuff was doing in my car.
There are some Ice Age animals that are so perfectly preserved in permafrost that scientists have been able to find them still with all their soft tissue, hair, and organs. They even found a couple mammoths that still had liquid blood in them and I remember one scientist even tasting the mammoth meat. Also there was a mummy found in China that was so well preserved that she still had all her skin, hair, organs, etc. Her body was even flexible that you could bend her limbs as if she was alive. They even found her last meal still in her stomach and could perform an autopsy on her to tell you why she died. She died over 2000 years before she was found.
Who the **** goes “Oh, I just found this perfectly preserved, marvelous animal from the past - I’m sure I can take a bite!” Sir, respectfully, pack your own lunch.
i don't know about mammoth meat, but i'd try the tomb cheese! 27c.jpg
They tasted the mammoth meat? Why does that seem so awful to me? I know they teach you to use all your senses in 7th grade when using the scientific method but there are lines…
Yeah, aside from the fact that they're eating a historical specimen just so they can be a showoff at Never Have I Ever, there's probably some weird now-extinct bacteria in there that we're not adapted to. Let's please avoid another pandemic, especially so soon.

"The power required to make a 1000 decibel noise for one second is equivalent to the power of the entire sun for 4 billion years" A family member was talking about a "600 DB" car horn he bought over the holidays, and I was trying to explain to him that 600 DB is enough energy to destroy the planet and then some. Lol
Logarithmic scales are a bit confusing. Like earthquakes – a 7.0 is about 32 times more powerful than a 6.0 quake.
For every 5 dB increase, the sound is doubled. So 90 dB is twice as loud as 85. 180 dB is like a grenade going off right next to your ear.
Thank you for explaining this for those of us who didn't know the scaling
Load More Replies...The sound of shuttles launching is so loud that NASA has to dump a lot of water to prevent damage. The sound is enough to ignite grass 1 km away from its source
(Relatively) simple physics tells us that the loudest sound possible in air at standard temperature & pressure is 194 dB. It's a compression wave, and there are limits to the possible pressure. So, BS to all of this.
My friend once got a sound system for his car that could apparently kill you if he turned the volume all the way up. He was very proud. Death by Slayer - every metalhead's dream I guess.
My uncle (sound tech for concerts and avid speaker tweaker) sweared he rigged up some sound system like this and 13 yr old me challenged this, the whole system was brought down by a 13yr old playing ushers ‘pop ya collar’ summer of 2001, I killed it with usher.

Load More Replies...The key to eternal life is coded into all known DNA cells but so far proven impossible to crack. Every known living thing generates, adds, becomes bigger, better, stronger faster up to a certain point to then suddenly reverse and we don't know why. When a baby grows it's cells form al sort of usefull things. At around 21 years old the process reverses and science can't figure out why. Technically we should be able to regenerate indefinitely.
It always amuses me that as a woman, I can grow an entirely new human, but I can't regrow a lost limb/organ.
Maybe look at it like you aren't growing it, it's growing itself! You are just feeding that growth, still pretty amazing that we and it can do that.
Load More Replies...this is a steaming load of barely coherent pseudoscience. i *think* it’s trying to say that our cells age at a sort of pre-programmed rate and for reasons that aren’t immediately obvious, since some organisms’ cells do not age (ie the telomeres of their chromosomes don’t shorten with each cell division whereas ours do, until the telomeres are gone and the cells can no longer divide). individuals aging either somehow improves their evolutionary fitness, or the process is blind to evolution because the cells don’t stop dividing until we’re so old that statistically we’ve died of communicable disease, injury or predation - and as such have already had as many children as was possible for us to have (and we have helped them out as much as we can). anything that happens to an organism after reproductive age is broadly exempt from evolutionary pressure. (apologies for the vague discussion, it’s late and I should be sleeping)
I'm not sure thats entirely accurate. They do keep regenerating, but not as fresh cells. Sort of like washing a shirt, it's always clean but never new again. Your cells are sort of refreshed but not brand new cells. I may be utterly wrong, I am far from any sort of scientist but I heard it on QI.
Yes, it's to do with telomeres. It's been a long time since uni for me, but there's part of the cell called a telomere that has finite amounts. I think it depends on the type of cell but say when you're born a cell has 32 telomeres. Each time the cell divides everything is replicated everything is duplicated apart from them. So first gen has 32, 2nd gen has 16, 3rd 8, 4th 4, 5th 2- after that the cell dies. Because cells can't replicate indefinitely we age and die.

Load More Replies...A mirror is technically a time machine. When you look at your reflection, you're not looking at your ACTUAL reflection, you're perceiving photons that hit the mirror an immaterially short time before and is just now hitting your eyes. So you're actually seeing a picture of yourself from the past. That's a vast oversimplification but, yeah.
Hyjacking this fact to say that, because of the same reason as the mirror looking at the past, If an alien race the same distance away as one of the Nebulas Hubble observed were to look at Earth through a telescope, they’d see the dinosaurs
We made that mistake before and decided to check it out. But then we saw that there are no dinosaurs now 🥲

in the vein of this. We have never measured the one way speed of light. It very well could be that light travels twice as slowly one way, then twice as fast the other. It doesn't break the physics and we may never know the truth.

Load More Replies...True, but, to a lesser or greater extent, this is true about ALL things we see and hear. Both light and sound take time to travel.
That doesn't make it technically a time machine. Also, this is just how vision works. Literally everything you're looking at happened in the past.
In the entire records of human history, there are only 16 instances of recorded hammerhead shark bites on humans, and not a single fatality.
If you think about it, their mouths aren't really well positioned to bite something as large as a person; it's not what they're evolved for. Hammerheads are generally bottom feeders, sweeping the sand for invertebrates and small buried fish and rays. When Great Whites attack, they can kill because they're evolved to eat large marine mammals like seals, and I know it's not remotely a new idea to point out that a human swimmer or surfer looks a lot like a seal from below, but if you look at it beyond silhouette, it's really not a big jump at all from the size and basic body plan of a seal to a person.
And in general, we are not as fatty as seals, and taste bad, so they spit us out
Load More Replies...Because tiny mouths? Good luck getting my f@t a$$ into your mouth Mr Hammerhead. Great Whites on the other hand....
when I saw one at the aquarium I thought I was seeing a cartoon come to life. even tho I knew what they looked like already, nothing is stranger to see. (for me at least)
Thank you. There tends to be a major disconnect between animals perceived to be deadly and those that are actually deadly. For example, normal honey bees are actually quite deadly.
And how valid is the source of this statistic? Indeed, what is the source?
That’s only because they talked to the survivors. Perhaps the hammerhead kills and leaves no traces?
1.3 million earths can fit inside the sun. 5 BILLION suns can fit inside the largest star ever observed, UY Scuti.
We’re actually really tiny when it comes to the universe. The planets and stars are so far apart that it takes years to get there. If the Milky way was the size of the United States, the sun would be the size of a white blood cell
Go to YouTube and watch the channel "Red Side." Really cool videos of graphically represented size differences. The "visible universe relative sizes" one will make you feel tiny. (Disclaimer: It's not my channel or that of anyone I know. I just think it's cool.)
UY Scuti is what Kirk says before asking when the warp engines will be back on line
So 6,500,000,000,000,000 earths fit comfortably inside UY Scuti. And by the way, even as the Sun is 1.3 times (I guess by volume) larger than our Earth, the Sun's gravity is only about 27.9 times that of Earth
... on the surface. 1.3k, right? Inside, gravity is a lot stronger.

a photon of light doesnt experience any time from the time it is emitted to the time it is absorbed. It was born, it died, all in one instant.
Sure am glad I didn’t drop any acid before spending time with this thread!
Photons which are "born" inside our sun take millions of years to get out of the superdense core. They bounce around like a flipper ball forever until the finally reach the surface and then its just a sprint of 8min to earth... So the light we see is actually millions of years old.
millions of years from our perspective … if the photon itself was somehow sentient, it would not experience the same passage of time, due to its speed
Load More Replies...How does that work if we see light from a star light-years away? Wouldn't the photon have lived that many years(-ish) ? (I *really* wish I'd studied physics in school - would've loved it so much more than the biology class we were forced to take...)
Google "light cones". Basically relativity says that space and time are linked such that the faster you move through space, the slower you move through time. Massive particles would require infinite energy to move at light speed, but massless particles like the photon can *only* move at light speed, so all of their motion is in the spatial dimensions and none in the temporal dimension(s, that we know of). Because of length contraction in the direction of motion, from the perspective of massless particles, there is also no distance between where they're emitted and their final destinations.
Load More Replies...True. There's a twist to this though. When light passes through some glass or water for instance, it slows down. And relativity says that because it travels more slowly than speed "c" it does age, it does experience time. And yet it doesn't. This is an interesting paradox.
I'd go out on a limb and say a photon cannot experience *anything*, even if it happened all at once.
Photons don't have valid frames of reference.
Load More Replies...It undergoes a change from existence to non-existence. Thus, since “time” is actually just a measurement of change, a photon does “experience” “time”.
I read "a photo of light" at first, which made it absolute gibberish lol
Apart from hosting life, the rarest thing about earth may be its eclipses. It is a complete coincidence that the moon is the same size, and orbits in the path of, our sun.
Wow, talk about oversimplyfying... the moon is in no way the same size as the sun.
Everyone, and I mean everyone, knows the sentence referred to the same apparent size. It’s so obvious that the word could indeed be removed. But I guess some people could not resist showing the world their infinite wisdom.
Load More Replies...It's not just that the moon is the same apparent size as the sun, but we're also at the exact right place in time to see it this way. The moon is slowly moving away from the earth, so a few million years ago, the moon was closer and appeared larger, so it would have totally blocked out the sun (no ring of fire, just complete darkness). In a few million years, the moon will be even further away than it is now, and will basically just cause a dip in the sun's brightness.
The moon is to earth ratio is one of the biggest planet is to moon ratios in the solar system
Isn't it the biggest now that Pluto has been demoted?
Load More Replies...Not only is it a complete coincidence, but it's a coincidence of TIMING not SIZE. The moon is gradually moving away form the Earth, and thus appearing smaller as time goes by.
It's also not a very impressive coincidence when you do the math, since *total eclipses will continue to be possible for at least another couple hundred million years.
Load More Replies...Sun and moon are vastly different in size, but their respective distances from earth make them seem comparable, and enables eclipses
"the moon is the same size"... as what?!? Not the Earth, nor the Sun. Eclipses are possible in anyplace where syzygy, the linear alignment of three celestial bodies, can occur. It can be a sun-planet-moon alignment or a sun and two planets. I s it rare? Yes. Is it unique to earth? No.
they’re referring to solar and lunar total eclipses, specifically. If the moon’s apparent size was smaller you wouldn’t get total solar eclipses and vice versa

In Newtonian physics it was generally accepted that a planet call Vulcan was closer to the sun than Mercury. The math needed some kind of extra planet to explain Mercury's weird orbit. Astronomers around the world for a couple hundred years would confirm a sighting, but it would never be there when you tried to use physics to predict where it would be. Even the famous french scientist that found Neptune with math predicted Vulcan using the same formulas. The idea didn't die until Albert Einstein changes physics with special relativity. Suddenly all the orbits of our planets make sense and Mercury has a weird orbit because it is so close to the sun.
Basically, smart dudes figured a planet existed when it didn't because their system didn't work out. It took changing the system to meet reality. Confirmation bias is a scary thing.
Edit: General Relativity not Special.
« smart dudes figured a planet existed when it didn't because their system didn't work out » No, they made an hypothesis to explain the observations, and that’s exactly how science works. One of the other hypothesis was an incomplete model and that led to the relativity theory. There is no « confirmation bias », op does not know what he’s talking about.

Load More Replies...That was not confirmation bias, that was science in progress. If a theory can't explain the observations, we then know it's flawed, and that we need a better theory to understand the phenomena it covers.

Load More Replies...I am kinda pissed on about Planet X, the 10th planet. The truth is that scientists denied the existence of Planet X for decades (perhaps only meaning to deny certain characteristics of the planet). Then another planet was found, but before its discovery was announced, they changed the definition of a planet, and only that decision is why we never heard of Planet X (and XI and XII). To be fair, however, Pluto did turn out to be smaller than expected and the most obvious alternate definition of a planet (revolves directly around a star and is large enough that gravity would round off even its solid matter) would include Ceres. On the other hand (a third hand?), counting Ceres as a planet would mean that Johannes Kepler's "God's law" (later named the Titius-Bode law after scientists who figured out precise calculations for it) happened to be correct... except for Pluto.
I’m sure they will find a definition that suits their needs.

Not super scientific but an animal fact TONS of people refuse to believe. Monkeys are omnivores and they love to eat meat, more so than fruits and vegetables. I mean Monkeys, not apes lots of people group them in the same category

Load More Replies...Turns out that there are very few mammals that are NOT potentially carnivorous, especially if you're not Catholic. (Too obtuse? When Catholics fast from "meat," they don't fast from fish or other cold-blooded creatures.)
A lot of herbivores eat meat now and then, if they can get it, since their environment cannot get enough critical nutrients in any other way...like phosphorus or calcium. Bones are rich in these.
That's different though, that's osteophagia. Primates eat meat on a regular basis

Chimpanzees also go to war. They will kill their “enemies” and in some cases will eat them.
Facultative omnivory is a LOT more common than most people generally know. For instance, deer will gnaw random bones and pilfer carcasses for bones for the calcium. Some deer go as far as killing baby chicks in ground-dwelling bird species for the same thing. They want the bones. Growing antlers every year puts a strain on the calcium in their own bones.

On average Mercury is the closest planet to Earth by a considerable margin.
Cool fact: on Mercury, the Sun can be in retrograde. Orbital movement and rotation of Mercury work against each other so the Sun moves extremely slowly in its sky. But when the Mercury is in periheliom, its orbital movement speeds up so much that the Sun moves backwards in the sky for some time.

My absolute favorite math fact: there are different "infinities" and this results in a larger infinity between 1 and 2 than between 1 and infinity.

You can always add another zero and don't even have a defined starting point. Therefore, more numbers between 1 and 2, than 1 and infnity. 🤯

the size of the universe is actually speeding up instead of slowing down.
we are actually made of stardust. so the stars died so you could exist.
If you think of it, we’re all 13.8 billion years old. The original elements in the universe were hydrogen and helium with tiny trace amounts of lithium. Some clouds of gas got denser than others and merged to form stars which were able to create the elements up till iron before they went supernova. Some of those stars left behind neutron stars which were ridiculously dense. Those neutron stars who were in a binary merged into each other and gave out heavy elements like gold, platinum, lead etc. All those elements travelled several lightyears over time and finally merged into a cloud 4.6 billion years ago forming the sun and our solar system. A couple million years later, life formed through a chain reaction of organic compounds. The asteroid crashed into our planet 65 million years ago which had some more elements that earth didn’t have before. Flash forward to today and here we are with all the stuff made up of elements that travelled long distances to make us and the world we live in
I think OP is referring to the fact that the rate of expansion of the universe is speeding up. The universe is expanding so fast that we can’t ever reach any point beyond the Local Group (a cluster of galaxies involving the Milky Way) as the space between ours and the next group is increasing. We’re trapped in a very small corner of space which we can’t get out of which kind of seems depressing.

Load More Replies...This is so counterintuitive that I've just been playing with an online circumference calculator. It's right, but I don't like it.
The ratio of 1inch/basketball is so much greater than 1 inch/Earth. Does that make sense? Is that why 6.28 doesn't change?
Dinosaur fossils existed while dinosaurs were still alive.
No. What they mean is that dinosaurs walked the earth for such a long time, that the first remains were already fossilized before the last one died.
Load More Replies...Human fossils often exist while the humans are still alive. They're called "Boomers".
I'm a boomer, and I cracked up at this... not fossilized yet tho.
Load More Replies...Fossilization can occur in days or weeks in the right conditions so… yeah.
There was also archeologists in ancient Egypt studying even ancienter (is that even a word) Egypt. I know it's not as old, but I always found that interesting. And gives you perspective of just how long Egypt was powerful.
Peanut are not nuts. Neither are cashews. Peanuts are legumes. Cashews are seeds.
Just laughed coffee out my nose at this one lol
Load More Replies...wait I thought nuts (except peanuts) were all seeds? I mean what is an almond if not a fruit seed/pip...?
They are. But so are beans. Technically peanuts are more closely related to pinto beans than almonds.
Load More Replies...I forget who says it. But a great scientist said once “if you look anywhere in the universe, you should see an equal amount of mass”. I think this is the the cosmological principle by Einstein I wanna say. Well the “Hercules-Corona Borealis Great Wall” doesn’t care. It is a huge group of galaxies forming a giant sheet-like pattern which is about 10 billion light-years long, 7.2 billion light-years wide, and almost 1 billion light-years thick. Mind you our galaxy is only 200,000 light years across. Also the universe is only 13.8 billion years old. So.. this wall also contradicts theories about the evolution of the universe. The structure is 10 billion light-years away, which means that we see the structure 10 billion years ago, when the universe is only 13.8 billion years old, and its light was just approaching us. The 3.8 billion year span of time is too short for a giant structure 10 billion light-years long to form. The mind boggles.
It’s called inflation and is one of the reasons why our universe is the way that it is
Load More Replies...“if you look anywhere in the universe, you should see an equal amount of mass” as a statement is usually just written as "the universe is isotropic". It's close to true, but has a few subtleties that I don't want to go into now.
And we think we are the only living beings on this earth in the whole universe?????
A pregnant woman carrying a daughter is also carrying all future grandchildren from that daughter at the same time.
That's true, it's not only by choice of one's path in life. It is also physical factors of being fertile, biological changes/issues in the future, and all that jazz. Edit: corrected grammar.
Load More Replies...It'd be more accurate to just say that female fetuses already have all the eggs they'll ever have in their lives.
I remember learning this in school. There was some kind of TED talk about it warning us that we need to take care of our health because not only would our daughters health be influenced but their daughters too. Whether we take care of our health today or not will have an impact a hundred years from now
St. Anna, but minus spermies she can maximally do same devilled eggs.
yes it is. females develop all of the eggs they will ever have while in the womb. So when pregnant with a girl your carrying all of you potential grandchildren too.
Load More Replies...There are different sizes of infinity
Fun fact, you *are* the center of the universe (as is absolutely everything). Technically, the 'center' is the point from which all edges are equally distant, and from any given point, the edge of the universe is an infinite distance away. (Sorry if I didn't explain this very well)
There's a hotel with an infinite amount of rooms, and all the rooms are occupied. Another quest comes in and asks for a room: "Sure, just a moment", the clerk says. He then goes to room 1., and asks the person there to move to room 2 and tell the one there to move to room 3, and ask the person already in room 3 to move to room 4 – and so on. And so the new guest gets room 1, and everyone still has a room. In an infinite hotel, that was already fully booked.

Happily I keep adding more, 14 last year, more this year, and I have seeds of others still to grow...they will go to other people with more space than I have...trees are so beautiful, and underestimated, amazing plants.
Apparently they no longer use that as a measurement because it's far harder to figure out how many grains of sand there are than stars in the galaxy.
Load More Replies...A gamma ray can strike us any time and wipe all Live on Earth out.
Gamma rays form when blackholes consume so much from their accretion disk that they expel tons of energy, when stars go supernova, when neutron stars collide etc. so far, it’s highly unlikely for any of these events to happen near us any time soon
er surely this depends on how far the exploding star is, how intense the gamma ray field is, etc.,? I mean gamma ray bursts are emitted in nuclear explosions but life on earth still exists.
Gamma rays are hitting us all the time. I think you mean a Concentrated Pulse of Gamma Rays
The actual name of the phenomenon is Gamma Ray Burst. Long story short, as stars collapse, they send out an immensely powerful flash of gamma radiation in random direction. As it is a wavelength of light, it travels at the speed of light, so it could hit us at any given moment and completely and utterly annihilate all life on at least one half of the planet, causing devastating havoc on the other half. Luckily, they have to be aimed very precisely to affect us at all, and they're not all that common - they happen only once a day or so.

Wombats' poop is cube shaped. Not sure that counts cause I believe it though?
I met an austrailian who kept leaving brown rubiks cube in my bathroom. I guess they're not rubiks cube
Wombats will also 'extend' their burrows during emergencies such as bushfire, for other animals to take shelter. And, God please don't, hit one with your car, you might survive, your car won't..
There's even been a scientific study to determine how far down the digestive system these little cubes form. At the end or well before the end.
Benford's law, absolutely mindblowing: An observation that in many real-life sets of numerical data, the leading digit is likely to be small. The number 1 appears as the leading significant digit about 30% of the time, while 9 appears as the leading significant digit less than 5% of the time. If the digits were distributed uniformly, they would each occur about 11.1% of the time. It has been shown that this result applies to a wide variety of data sets, including electricity bills, street addresses, stock prices, house prices, population numbers, death rates, lengths of rivers, and physical and mathematical constants.

Lol, this is silly. Of course 1 is most often the leading digit in data sets. Most data sets are counting or measuring, and we start with 1. What's mind-blowing is that there's any need for a whole law to be made about it.
A mountain on a neutron star is only a few inches high. The amount of energy "lost" for the Earth to orbit around the sun is equivalent to running a space heater. The mites on your eyebrows & eyelashes have no anuses and will eventually explode from a buildup of fecal matter. Dog cancer is contagious and has been traced back thousands of years to one individual. Human lice cannot live on any other animal and using the "genetic clock" an approximation can be determined on when humans first started wearing clothing. The name for natural gas comes around because coal gas was refined for lighting but the other came straight out of the ground. Wallabies have square poop. People have fallen from heights above 18,000 and survived. Stewardess from Yugoslavia Airlings (bombing), a girl fell into the Amazon rainforest and WWII aircrews falling from their planes. Honey is still edible after thousands of years under ideal circumstances. There was a chicken that survived getting its head chopped off and became a circus oddity (it eventually choked to death after its owner fed it). Dinosaur fossils have been discovered with soft tissue inside the bones, paleontologists determined the color patter of some species and an armored dinosaur mummy was found in Alberta. The moon moves away from the earth at a rate of an inch a year.
Not technically when humans first started wearing clothing, but when humans lost their body hair. They can trace when pubic lice and head lice last shared an acestor. After that they evolved separately and didn't interact. It's just assumed we started wearing clothes at the same time we lost our body hair.
The chicken still had most of his brainstem, so not entirely headless. Horrific that he was kept alive, although hopefully he had zero awareness with only a brainstem, and not even an entire brainstem. Mike the Headless Chicken - Wikipedia https://en.m.wikipedia.org/wiki/Mike_the_Headless_Chicken
Meh. I fall from a height of well over 18,000 μm every time I take a step.
"A mountain on a neutron star is only a few inches high." Photo, or it didn't happen.
A neutron star is really dense so it has a high amount of gravity. The gravity is so much that if it collapses a little bit more, it will become a black hole. The mountains can’t reach a high altitude with all that so they’re just a couple inches tall

Load More Replies...If the universe really does collapse into a black hole, that would mean that such a black hole would contain all of the information in the universe throughout time. Now consider that from a photon's "point of view," the universe was formed and dies in an instant. The entire universe, therefore, would be merely the information found in an instant's worth of photons projected throughout time and space by a black hole. What's more, a universe that collapse onto itself would not be oscillating, since time gets lost in that Big Crunch; there is not one universe after another after another. It's just one universe wherein time is a function of volume.
How well do you manage confirmation bias? How regularly do you change your opinion on things that were once emotional matters or important to you and in a direction that does not comfortably line up with other beliefs. If you adopt positions that better line up with some group that you identify with, that doesn't count. If it's in your self-interest or the interest of someone you care about, that doesn't count. If it's the trendy position of comedians or politicians or talking heads or TV shows that "take on tough issues," that doesn't count. In all those cases, you're decreasing cognitive dissonance, not allowing it to change your mind.
Far sadder than that. People decide "truth" based on how it makes them feel.
