One thing that I have accepted in this lifetime is that there are infinite things I won’t ever understand. I can’t wrap my head around how humans created such ornate buildings hundreds of years ago, and I’ll never fully grasp how the internet works. I cannot fathom the fact that our galaxy contains billions of other planets, because honestly, even my smartphone blows my mind.
We are lucky to live in an age where we have so many more answers than we did a few centuries ago, but that doesn’t mean our brains can fully comprehend it all. Redditors have recently been discussing concepts that they’ll never quite grasp, despite how many times they’ve been explained, so we’ve gathered some of their thoughts below. Enjoy scrolling through these topics that might be beyond your realm of comprehension too, and be sure to upvote the ones you'd like to understand!

Why America doesn’t provide healthcare & schooling to their citizens.
So, wait a sec. Abortion, bad. Having babies, good. Maternity leave? NOPE!
Load More Replies...Because they don't want to. When health care is tied to jobs (even if it were good), it forces people to stay at a bad job. It puts them at risk of not getting health care if they leave for another. And as for schooling, it's intentionally designed NOT to give the poor an education, designed so that only the wealthy and privileged can get an education. It's feudalism by capitalism, the powerful and the serfs.
True, especially because richer neighborhoods = better funding for schools
Load More Replies...Because conservative Americans only believe in what will help THEM, and not what will help the entire country.
This 100% We need the biggest blue wave this November. Finally defeat the Republicuunts and their fascist orange god king.
Load More Replies...Costs and because they wanna keep people stupid so that it's easier to control them.
Because rich people and Republican politicians prefer the population to be stupid. The rich because they need cheap labor, the Republicans politicians because educated people do not vote for them. The lack of single payer healthcare is because ruling the world with the military industrial complex takes precedence over the health of the people.
Those who control American society approach all issues with a single question - "How can this help the rich?"
The "Why" is because (a) very wealthy people want to avoid paying a lot of money in taxes (like for funding schools), so they spend a little of that money to convince enough politicians to cut taxes, (b) people and companies that make a lot of money from healthcare spent a little money to convince enough politicians to not crack down on exorbitant pricing, and (c) those same politicians try to convince enough voters to vote for them using any excuse they can think of, and not talk about the things they are doing to make the people in (a) and (b) happy. If enough voters aren't paying attention, they won't hear or think about what's happening in (a) or (b) because some of the people in (a) own news outlets (e.g. Murdoch), and downplay what the people in (a) and (b) are doing with the politicians.
How Trump can still be allowed to run for President.
Any regular guy saying the things he constantly says in any post, podcast or YouTube video and the guy would be cancelled instantly. Old orange full of money says the same things "let's make him President again!" I guess? I am not sure I will ever understand.
This... never mind the felonies. People can't get a job or join the military with felonies. They ruin regular people's lives when they have 1 felony. This guy can run for president woth a bunch of them...wtf
Trump has never had a job, and never been in the military. He's never had a boss.
Load More Replies...He has been committing felonies for decades and has never faced any consequences and he never will. Hell, the man committed actual treason and nothing happened to him. He riled up and directed all those idiots to his bidding and they got punished, but he didn't. Manson did the same thing - he didn't actually kill anyone, but they still threw him in the can for life. Somehow, Trump is covered in teflon. You can't spell teflon without felon. Huh, just realized felon easily turns into f elon, lol.
Let's face facts: a huge percentage of the population are asshats and Trump resonates with them.
He is running on hate. There are a lot of people feeding on that hate.
My sister said, when he said he was running again, 'he believes he won the last election, so he shouldn't be able to run again because you can only have two terms'. On the other hand, he has been found guilty of crimes in multiple states, so that should be enough to disallow him running.
Should be, yes, but there's nothing in the US Constitution that prevents a convicted felon from running for office unless the conviction was for treason or sedition (and even that is open to interpretation owing to the ambiguous wording). It is even possible to run an election campaign from prison.
Load More Replies...My view is that anyone who would vote for him is racist, greedy or stupid ... or some combination thereof. I used to naively believe that our country would always progress ... maybe at various speeds and encountering various problems along the way, but we would eventually get there. I'm still depressed about my realization that that may not be true, that democracy is fragile. Vote Blue!!
There are church leaders who tell their congregations that they must vote for Trump or face everlasting fire. It's a brain washed cult at that point. Note: normally, I'm all "everyone has reasons for voting and thinking differently, respect each other" but the MAGA cult is not operating in the same reality as facts, laws or consequences
Those church leaders are violating the separation of church and state clause in the Constitution, and their churches should lose their tax-exemption status. The agreement is that the State remains religiously neutral and religion stays politically neutral, but of course both sides break that agreement all the time.

Space, it's so big that it is unfathomable and I think it's expanding?! Into what? How did it start? It's all a mindf**k .
And it’s expanding at such a rate that the galaxies there at the edge are moving away from us at a rate faster than the speed, so their light will never ever reach us. The part we can see, is the Observable Universe. Beyond that we’ll never know.
Well, we'll never know until Zefram Cochrane invents warp drive.

And it is likely just one of an infinite number of universes that exist.
We all need unanswerable questions like these to inspire us with awe. I'll add in "is the universe curved or flat?" If it's curved, it will eventually circle back onto itself. Are there other universes? As to how it began, I love how the general answer seems to be the same as for "If God created us, who created God?" Always was, always is, always will be.
Funny I was just pondering this while drifting off to sleep the other night. Like what is out there, how can it not end, And if it's does what happens if you come to the end.
Since the dawn of man is really not that long As every galaxy was formed in less time than it takes to sing this song A fraction of a second and the elements were made The bipeds stood up straight, the dinosaurs all met their fate They tried to leap but they were late And they all died (they froze their a**es off) The oceans and Pangea, see ya wouldn't wanna be ya Set in motion by the same big bang It all started with the big bang It's expanding ever outward but one day It will pause and start to go the other way Collapsing ever inward, we won't be here, it won't be heard Our best and brightest figure that it'll make an even bigger bang
100 million year ago when the dinosaurs roamed th earth we were at the top of the galaxy. Now we're at the bottom ish. Mind blowing
And we have known this only for about a 100 years. Before Hubble discovered galaxies and that they're all moving away from us; our knowledge of the universe was basically Milky Way, our own galaxy. Just think about it. For millenia our ancestors looked at the sky in wonder and all they were wondering about is quite insignificant in the Cosmological sense.
The universe is a self contained reaction the proceeds into uniform chaos. At the exact point of uniform chaos a separate universal 'big bang' will occur only one that is governed by a completely unique set of units versal laws, values and constants. This reaction also occupies the same space and in fact, the amount of physical space of the universe never changes. The only change is how matter is organized within the boundaries of the universe. Think of it like a snow globe. It isn't actually snowing, it only looks like it's snowing.
Why after thousands of years of history behind us, people still suck. You’d think we’d be improving but no, sometimes it feels like we’re actually getting worse.
Think of it this way: people haven't changed much, but culture has mostly improved. For example, many places in the world had little or no police (or equivalent) that protected regular citizens. Often, soldiers in wars were not supplied with food, so the soldiers would steal food from local citizens, sometimes injuring or killing those citizens as well. Nobody in power cared. As another example, at the end of many, MANY, wars in some parts of the world, the winners would either kill their opponents or sell them as slaves. It didn't matter which religion the victors claimed to follow, they all behaved this way. The conflicts between modern Israel, Palestinians and Lebanon would be fundamentally different today if the founding of Israel included selling the Palestinians into slavery or killing them. So, as bad as the situation there has been and is today, at least far more people survived than would have in previous centuries. Culture is improving, but it doesn't have a solution for everything.
Speaking of Israel. I never did understand why when the location for a homeland for Jews was being considered they thought putting the Jews in the middle of where every other country hates them would be a great idea! It seems to me that was clearly a recipe for endless war.

Selfishness combined with power is why. If you're alone, you can't force people to do what you want. But organize by religion, social groups, jobs, etc. and you can organize hate.
People suck more than ever. One must have thought that the information age would put an end to stupidity. But neh! It's still going downhill. The majority of dumb people don't realize that they are dumb and I think those people are way happier than I am. If only I were a little dumber, so that I wouldn't have to worry about something like that.
The nature of a person is selfishness and self-preservation. Everything everyone does is to benefit themselves in some way. Altruism doesn't really exist. Those that seem to be altruistic are actually doing it because of the way it makes them feel, so even that, in a way, has a selfish motivation.
Because we are a product of our evolutionary history and our behaviour is adapted to keep a small community of hunters and gatherers safe. We’ve only been farming for 12,000 years and living in cities for about half that. Evolution hasn’t had a chance to modify our behaviour yet. We have the intellectual capacity to do this but that doesn’t override 70 million years of primate evolution.
Technology allows ways to be a lousy person to evolve much more quickly than people do.
I'll go, for me it's the whole transformation from caterpillars to butterflies. I understand what they DO but it's the most alien s**t ever that a worm just decides to rearrange itself into a winged creature that looks nothing like it did before.
It's even more bizarre than that - between caterpillar and butterfly stage is mush, it digests itself!
Yeah, it's amazing how it keeps all the necessary parts in the right place.
Load More Replies...Here is a video that summarizes how it works: https://www.youtube.com/watch?v=uK_iZZ4Bx2o
That's how, the question was why and how evolution put it all together, I would guess very slowly.
Load More Replies...Yes and the evolution of twig insects baffles me in the same way...what consciousness in the DNA recognises the twig and the leaf and then emulates it as camouflage on a cellular level fgs?
No consciousness is required in DNA, and no recognition on the part of the insect. The insects that looked the most like twigs got eaten less, and therefore left more offspring. Rinse and repeat for millions of years and you get a stick insect. The only way evolution can operate is through variation in breeding success.
Load More Replies...Chinese Lantern Flies do this too! They actually evolve several times AND change colors until they burst free with wings.
Same for maggots to flies. Trying to think of insects that don't have a larval stage.
There are two main types of insect -- those that have nymphs such as dragonflies and grasshoppers, and those that undergo full metamorphosis from a grub or caterpillar such as butterflies and flies.

I still don't know what this means (but I think they mean "inner monologue" not "dialog"). Do they just mean thinking in words? If so, lots of people don't think in words. Well, probably most people have some words or think about certain things in words, such as as practicing what to say to someone. But generally I don't think in words. It would be really slow to think everything in words. So, I'm thinking "inner monologue" must not be the same as simply thinking in words.
I have two or three different inner dialogues. Sometimes they all are going at the same time which makes it very hard to concentrate on anything
I have no inner dialogue, no other sound in my brain, as well as aphantasia which means I have no visuals in my brain. What goes on in there is beyond me. I have no idea how I think, or read, or anything. I just do- one of the strangest things to me and my friends
My health insurance
You mean I have to pay every time I use it even though I pay monthly? Unless I pay a big amount then I pay less? But if I don’t use it they just keep it all? But they don’t cover my teeth or my eyes?
Omg this...I just started paying for my own insurance when I got married. Was on state insurance for a long long time and they pay for most anything. Now I'm getting bills that are higher than my 600 dollar monthly cost ( that's for me and my husband) I don't fcking get it and I'm losing it
American health insurance is legalized fraud. Saying this as an American.
Load More Replies...In my "developing third world" country, if i happen to be ill, ill go check my self to the designated clinic, most of the time the closest to my house, that is stated on my health insurance system. If the clinic cant handle my illness, the doctor would make a recommendation letter for me to check my self to the nearest hospital. From then on, any procedures necessary to treat me, as long as the doctor recommend me to have one, i will have them for free. Other case for emergency, road accident? Sudden Stroke or heart attack or any emergency? Go to the ER, the insurance will cover all of it. Everything for less than 10$ a month. A third world country probably not that bad huh...
It's not just Health Insurance, you make a claim after 10 years of driving with no incidents or making no claims on your house and you are penalized. So, after paying $12k for coverage you ask them to pay $2k, less deductible, and you are threatened with cancellation.
Sweden has some civilized insurance laws. Here in America profits are the god that everyone worships. So insurance companies get to rip everyone off as much as they like.

Basically, it's a form of gambling: the insurance company "bets" you that you won't have an accident/get sick/whatever. You say "You're on!" and you pay them a specified amount of money, every year (or whatever). IF you DO have an accident/get sick, THEY pay you the amount of money that you *would* have had to pay, if you hadn't been insured - usually *WELL* above what you would have been able to afford. If you DON'T have an accident/get sick, they get to keep your money, every year that you don't get sick/have an accident. Just think; you're on a low to medium salary, and you run into a brand new Mercedez. The owner sues you for the cost of his wrecked car. How the hell are you going to pay him? IF you have auto insurance, they will either pay the lot, even if you've only been with them for a few months, or at the very least, make the amount that you do have to pay, minimal. So insurance basically breaks down to how much you're willing to gamble with life. Pay insurance, (cont)
cont: Pay insurance, and never have to make a claim? Well, they keep all your money, and you wonder, bitterly, why you gave them so much money for nothing. On the other hand, if you DON'T have insurance, you COULD find yourself in a position to pay for an accident that could bankrupt you and leave you and your family destitute and living on the street. (Medical insurance doesn't count - you Americans don't have any worth paying for!)

Quantum mechanics. No matter how many times it's explained, the idea that particles can exist in multiple states at once or influence each other instantaneously across vast distances just feels like nature's most elaborate inside joke that I'm not quite in on.

How a basic wax record and player works. I get it’s a grove that is tiny hills and valleys and the needle picks up on each little one but how the f**k does that equal a voice coming out of a large metal tube. It’s witchcraft as far as im concerned.
At the most basic, the wiggly grooves in the recording move past the needle fast enough that you can hear the vibrations of whatever is attached to the needle, as long as it is rigid. It's not loud if you just use the needle. Attach the metal cone to the needle and the vibrations are enough to make the cone vibrate, which is loud enough to hear. This video link below shows someone playing a record with just a plastic 5 pound note. The groove makes the corner of the plastic note vibrate, and the plastic note is stiff enough that you can hear it vibrate. https://www.youtube.com/watch?v=kUlu-XjCgtk

All sound is just air pressure vibrating and moving an ear drum membrane. The grooves in a record are just a frozen physical representation of those vibrations.

By the way, on the right is an Edison Standard cylinder phonograph; I own one.
The electoral college. No matter how it’s explained to me, it will never make sense to me that we award arbitrary points to states over going what the majority of voters want.
That system possibly made sense in the 18th century. But, because Americans have this pagan cult of their Founding Fathers, they somehow got stuck with it because clearly a bunch of slave-owning rich people from 250 years ago figured out EVERYTHING. So there.
Add to that the fact that it is just another tool for Republican politicians to use to win, like gerrymandering and election official corruption. Because if left to just the popular vote, Republicans would lose in most states.
Load More Replies...The Founders were worried that many people highly qualified to be president would be unknown outside of their region. (No TV or other nation-wide media.) The electors were supposed to be people with broad experience in national politics who would be familiar with candidates from other regions. The Founders also were afraid that the larger states would dominate the smaller states if the president was elected popularly. This was all done in a rush at the end of the Constitutional Convention. Many delegates were unsure if they had got it right but they told themselves that was what amendments were for.
That's the first explanation I've been given that made sense. Thanks. I feel like I've actually learned something.
Load More Replies...Worse for me is the fact that each state works it differently - in one state the candidate with most votes gets ALL the electoral college votes, while another state splits the EC between the candidates. Surely they should all work the same way? Even better, just give each candidate the actual number of votes they get!
It's not arbitrary. The number of Representatives in the House for a state is based on the population of that state which is divided into districts with each district getting a Representative. States with more people have more districts and more Representatives. The electoral college is composed of delegates from each state and the number of delegates each state has is equal to the # of Representatives they have in the house plus 2 for the # of senators each state has. In most states it is winner take all which is why Biden got all of GAs 16 points when he only had 11779 more votes than the other guy. The census taken every ten years can change the number of Representatives and therefore electoral delegates a state receives and that is one of the reasons it is important for citizens to participate in the census and also to vote. We are a democratic Republic. In a pure democracy the rights of minorities are largely unprotected which is why gerrymandering is a bad thing in our system.
The founders did not quite trust direct democracy. The electoral college is a compromise design. Remember, they were making it up as they went along.
Each state has a popular vote. The winner of that popular vote then gets the electors for that state. Win 270 you're in. That is the nature of a representative Democracy (i.e. Democratic Republic) If we elected presidents by popular vote candidates would simply ignore less populous states and campaign only in those areas where large populations are concentrated. This is the United STATES of America. By having to accumulate electoral votes candidates must convince virtually every state to vote for them. At least enough to accumulate 270 electoral votes and not just the ones with the biggest population.
However, the electoral votes are not distributed directly by population. California has a population of 38,889,770 and 54 electoral votes, about 720,00 people for each electoral vote. Wyoming, on the other hand, has a population of 586,485 and 3 electoral votes which is only about 195,000 people for each electoral vote. So a Wyoming vote for president has 3.7 times the influence of a California vote. If states were given electoral votes only on the basis of the number of its congressional districts (which are based on population) the disparities would be negligible. But each state also get electoral votes for their US senators, which is always two regardless of the state's population. We could remove those Senate-based electoral votes by constitutional amendment, but the smaller states would block it because they are advantaged by the current system. And smaller states tend strongly to vote Republican, so the national GOP would also be opposed.
Load More Replies...It was so each state had representation, but it's become more of a hinderance to democracy than a help. I don't think the founding fathers took into account just how stupid people can be. But the EC does need to go. We should be a true democracy now where the popular vote is what counts.
it's a system that is no longer needed. It was created here in the U.S. to balance out the African American vote only counting for 1/3 a person when they were freed from slavery. It was to give voice to them and under populated areas. Yet now, with our large population and equal votes, the Electoral College is NOT NEEDED anymore. 2016 proved it fails.
What the Hell are you talking about? The electoral college was created in 1787: it was in 1870 that the right to vote was granted to former slaves by the ratification of the 15th Amendment, and their votes were equal to those of every other voter.
Load More Replies...The idiotic "electoral college" was designed with the same "thinking" that had two senators from each state, no matter how populous or empty each is (e.g. Wyoming less than 600,000 and California over 39 million). It was meant to avoid some states from having too much influence, but that was at a time when yankland didn't span the continent, and it was 100 years before the telegraph (let alone other media) and contacting distant places took weeks, not minutes as it does now. The "ec" needs to die. Two senator per state, however, still makes sense.
Senators were intended to represent the interests of the states' legislatures in Congress. For over 120 years, they were elected by those legislatures, not by popular vote. It was not until ratification of the 17th Amendment in 1913 that senators were elected by popular vote.

Load More Replies...It all boils down to wings having lower air pressure on the top side of the wing due to the air moving faster over the top of the wing, and higher air pressure on the underside of the wing. The higher pressure literally pushes up, keeping the plane in the air, as long as the air is moving fast enough over the wing.
it's not so hard to visualize if you hold your hand out of the car window going at least 40mph, and tilt your hand. You can feel the lift and dip. Just scale that up and there you have it.
I understand the principles, the thing that blows me away is that the wings are so long, and the body so heavy, there is such a small connection - the load on the connection between the wings and the body must be incredible.

How a chicken can make a whole egg everyday! I’m always just blown away
Everyday. A whole new egg. And sometimes two a day! Why is this not talked about more?! Lol.
I ate a lot of organically breeder chickens in my village in childhood. After cutting, I noticed their stomach was full of eggs. They were of different sizes at different growth rates.
Stomachs? Wouldn't they be in the uterus (if chickens have them)? Now, I have to go look this up.

People with XX chromosomes (cis women and Trans men) are born with a limited number of ova, will never produce more than that many in their lifetime.
Not so limited! Women have all their eggs at birth and don't produce them throughout their lives like men do sperm. They can have 2 million eggs when their born, and the number gradually goes down through attrition to about 1-2 thousand by the time they hit menopause. Ladies, don't try to play roulette with birth control. The odds are on the house!
Load More Replies...Above all: why? Other species only give birth to offspring if they have been fertilized beforehand. But chickens won't. And other species only give birth once, maybe twice a year, depending on the living conditions. A chicken lays an egg every day without fertilization. Why?
They weren’t originally able to lay an egg a day. This has come about by selective breeding. If you think about it most birds don’t lay continuously either.
Years ago when you bought a chicken you would find semi formed eggs inside. They are tasty

Environmental impact has a huge role I think, 8 billion brains in 8 billion different and unique to them environments across a whole planet, everything from what's in the food and water, atmospheric difference such as altitude, social interactions, relating to the world in their little corner all firing neurons and creating pathways as unique as a fingerprint.
I had MRIs while in hospital and one night I was the last patient to be scanned. We were waiting a while for the porter to come take me back to the ward because it was busy so I asked if I could see the scan? Yup I can and omg! It's sooooo amazingly weird seeing your body in a whole different way! Especially your brain activity and having the technician explaining how it all worked!...... So at least now I can definitely reply if someone ever says to me - "Omg do you not have a brain???"... Me - "Yes, I've actually seen it!" 😄
What blows my mind is those with an autobiographical memory, like the actress Marilu Henner. Just name a date and they'll tell you what they had for breakfast, what the weather was like, what they were worried about that day. Crazy. Or those with photographic memories and can draw a scene from a memory in exact detail.
There are several charities that you can donate your brain to after you die. The more people donate, the quicker we'll discover the causes of some of these horrible diseases and maybe even fix them.

Healthcare bills - they are engineered to not be understood.
When I was living in the US, I once accidentally went to a blood work clinic that was out of my insurance network. I thought I’d have to pay a bunch out of pocket but the clinic just adjusted the cost down to what my insurance would pay. So the cost was tied to nothing whatsoever. It was mind boggling.
Never had one. I'm diabetic. If I lived in the USA I would be bankrupt or dead.
usually id be upset by comments like this. not this time.
Load More Replies...$0 years ago after a surgery, the bill I received charged me for medications that I brought in myself as well as other items I never received. I challenged the hospital. They reviewed the bill, removed those items and added more that I of course could not prove that I did not receive because they were given to me during the surgery, supposedly. I kept sending the bill back questioning various items. After a year, the hospital gave up. I found out later that where I lived there was a law that required a hospital to provide an accurate invoice within one year. I am sure that law has been removed by now.
I’m Australian and needed to take my daughter to hospital in the US, after initial payments they kept sending me more bills. I requested itemised bills for my travel insurance to pay for they dropped the charges and never sent me the bill, I don’t know how they get away with it.
Healthcare in the USA is an institutionalised scam. It's not like that in many countries around the world.

I'm a classically trained singer and will never understand how I can think of a certain pitch and then recreate it accurately.

Not every autistic person, but a lot of us have a certain thing we will obsess over, more so than anything else we get obsessed with. For me it is sound & mimicry. I looooove certain sounds, and how they can be arranged to make music. I became a bit obsessed with notes.sound frequencies, tonal quality, and how to mimic sounds. I can also play just about anything by ear on the piano or guitar. It's how I learned to speak 6 languages like a native speaker. I tend to learn by the way the words sound. On the flipside, I have RBF & am not good at social cues, so win some/lose some lol.
Humble brag? I can always accurately choose the exact right tupperware container for whatever I'm storing.
I had a little old lady who had been a music teacher tell me I have perfect pitch. I get admired for my singing voice but truly, and I always say this, it's just something I was born with. I'm glad because I LOVE singing, anywhere anytime. But I don't feel I deserve credit for it. It's like my eye and hair colors. It's just what I came with.
Same thing hear, but as a guitarist. How I can hear a chord and then just play that chord. Impress myself every time I do it.
i am not a trained singer but have been told by many that i have perfect pitch. idk how i do it either. i hear a sound, i sing that sound. unless i can't, in which case i just don't try LOL
Consider the Chinese, their languages use different tones; the tones are inherent in the word (like a syllable is an inherent to an English word). They are able to repeat the tone exactly the same every time they use the word - are they a nation of people with perfect pitch?

How when I'm playing an FPS game in Europe and aiming my gun at another players head who's in the US and pulling the trigger, electrical impulses are (roughly speaking) sent from my mouse to my computers motherboard to its CPU which makes the decision to forward it to my network card which sends it to my router to my 5G antenna, then through the air to a recieving cell phone tower a mile down the road, then down into the ground through cables again (I'm assuming) through the entire country to some major European backbone hub, then down into deep sea cables under the entire f*****g Atlantic ocean, through the same whole bunch of cables and switches and relay stations through HIS country as well and finally into his computer where he dies from the bullet a FRACTION OF A SECOND later.
And then we all complain about the lag and the high pings because the internet is just so f*****g slow today.
But anyway it's not so much that I don't understand how this all works technically, I do but I just can't wrap my head around how the information is able to travel as fast as it does for as far as it does. It's not just the distance itself but also just the sheer amount of devices and things the data packets have to enter and exit on the way, with computer chips running software making logical decisions on how to recieve it, analyse it and send it on its way again over and over and over again. And all of this doesn't even take a single second from start to end. Not even half of one.
I dunno it's just mindboggling to me.
Electricity travels at the speed of light, about 300,000km/second. From Europe to the US is about 10,000km. That means information (if there were no resistance) could travel there and back fifteen times in a second. Even with delays and laggy lines, that distance takes less than one tenth of a second. That's faster than you can blink.
light travels at about 2/3rds the speed in fiber optics as it does in a vacuum. London to New York one-way latency is about 30ms.

I have never seen anyone in there. And, it's right in the middle of town, where the rents are super high, because that's where all the overpriced tourist places are, miles from the nearest lake. Not that anyone's scuba diving in the lake, anyway. It's small and muddy.
Computer!! You take the rock!! You pound it into metal ore or something!! You put the metal together with some stringy bits of copper or idk whatever goes into circuits!! You run electricity through it!! It does math??? It's a rock!! How it does math?!?!?!??
Edit: if I had a 1 and a 0 for everyone who has explained computers to me based on this post I could build MULTIVAC.
To pick a much simpler example, a cake would seem magical to someone who just looked at the ingredients. The wrong ingredients or the wrong amounts would produce something that isn't cake. Edit: Regarding the comment in the original post "It does math??": The math part is actually a separate topic than the electrical part of computers. Computers are designed to use electricity to operate special circuits that enable the use of digital logic (Boolean logic). Logic circuits, when designed sufficiently (and rather complexly), enable math calculations. You could use something else besides computers and electricity to do Boolean logic and math calculations. For example, it's possible to design a complex network of pipes and valves powered by a waterfall to perform math calculations. It's just enormously easier, cheaper, and more flexible to use computers.
In other words, it’s not just the ingredients, it’s the recipe.
Load More Replies...When I was taking electronics engineering classes in college, the class that blew my mind was Boolean Logic. This simple form of math is the basis for all computer processes. A computer is nothing but a billion simple transistor switch circuits configured to do different math functions using Boolean Logic. That humans were so brilliant as to be able figure out how to configure simple transistor switch circuits to do a variety of digital gate functions and then to configure all those gate functions to become a computer, is really remarkable.
A computer is a finite state machine. A counter plus combinatorial logic, scaled to unfathomable bazillions.

That scene from Interstellar when they go to the planet for a bit, then get back to the ship and the dudes many years older. Why time passes quicker in different places in space.
It doesn't. Firstly it's not about different places, but different speeds, but for any individual time passes just the same as it does for any other. It's only in the theoretical case where someone's travelled close to the speed of light relative to another person and then returned to meet them that we notice a difference, but each person's time has passed no more quickly than the other's.
Not exactly theoretical, as astronauts in th ISS have been shown to have aged at different speeds than if they were on Earth.
Load More Replies...in the movie Interstellar, the time differential was due to their different proximity to the black hole, Gargantua (I think that was it's name). At least that was the process.

The internet. WHERE IS IT? How can things be stored on something that's not tangible?
The internet is just a huge network of connections between computers. Web pages and photos and all that stuff are stored in the computers, not the connections between the computers. If you unplug the internet from all of the computers, the stored information doesn't disappear, you just can't access the information anymore. Edit: By the way, the "Cloud" is just a marketing term for companies that set up a bunch of computers to perform the same things, using additional software that coordinates the computers to work together better, like storing photos and playing back videos. If 1000 people are watching the same video, they are likely receiving the video data from multiple computers, not just one computer, because it's easier and cheaper to design the service that way, and the service responds to commands faster. The software coordinating the computers decides which computer feeds the video data to each viewer, depending on how busy each cloud computer is. It's a lot like when people want to buy movie or sports tickets: One ticket booth is too slow for handling a lot of customers.

Black holes. Space in general, but black holes really get to me. So strong that light and other stars/planets can’t escape it? Where does it all go?!!
The diametre of a hydrogen atom 1.06 × 10^(−10)m, and the distance between the proton and the electron is 5.3x10^(-11)m. The diametre of a proton is 1.7×10^(−15)m, and the diametre of an electron is 1.0x10^(-14). That means an electron is 1/10,000 the size of a hydrogen atom, the rest of it is empty space. In one cubic metre of air, there are 2.70×10^25 atoms of hydrogen, so if you compressed all that one cubic metre of air via gravity, it would be smaller than one cubic millimetre. Even a cubic metre of iron would compress to less than a cubic millimetre if all the space were removed. It's the electromagnetic resistance that keeps atoms apart - remember, gravity is a WEAK force, not a strong one (e.g. magnets can defeat gravity), so black holes are incredibly dense gravity wells. A black hole weighing the same as the Sun would a ball only three kilometres across.
Basically, the singularity (core) of a black hole is the only truly solid matter in the universe. Everything else is more empty space than matter. So in a way, most of the universe is an illusion.
Load More Replies...There are some creepy basements in very old houses where all the matter of a black hole ends up.

I don't understand color. I think it's something about how the color we see is the color that wasn't absorbed and therefore the one reflected into our eyeballs, but I just don't really get it.
Yes. Take away (absorb) most other colour than green, then you see green. 👍 What I'm wondering, is if everybody sees green as the same color as me, or if someone sees it as yellow?? That interpretation is in the brain?
Load More Replies...It gets even weirder. Synesthesia is a neurodevelopmental trait that causes people to experience more than one sense at the same time by routing sensory information through multiple unrelated senses. One example of synesthesia is grapheme-color synesthesia, which causes people to see numbers, letters, or words as having distinct colors. For example, someone with grapheme-color synesthesia might see the number 5 as red or the letter S as yellow. The jazz musician Duke Ellington had this - he was also a superb artist. Think about it.
I think the OP's doesn't understand how eyes work. The back of the eye has a thin layer of nerves called the retina. It has tiny little transparent sensors that send a signal to the brain when a light particle (photon) reaches the sensor. Some sensors trigger when they receive red light photons, some trigger for green light, and some for blue light. If you see an orange, the orange light bounced off the orange into your eyes. The red light sensors trigger more strongly then the green light sensors when they receive orange light. The blue light sensors don't trigger for orange light. The brain takes the signals from the red and green sensors and interprets it as the color orange. How the brain figures this out is a whole different discussion.
OP was talking more about what makes that orange light orange to begin with.
Load More Replies...If you think you're in the dark, go talk to a colorblind person about colors.

Now to really confuse you. "Color" is just a name we give to a specific wavelength of energy on the electro-magnetic spectrum. How we PERCEIVE color is something else entirely. I can guarantee that what colors I see are not the colors you see and I'm sure that no one sees the same colors that anyone else does because the organic cells we use to perceive those wavelengths may be weaker or stronger than others. I'm red/green CVD and strongly so, I see about 1/10 the colors YOU (If you're normal) can see. Do I see 'red'... yes... but my varieties of 'red' are different than yours. This is the same for every color.
it is how the molecules in each color affect the light that shines on them.
technically it's how much light those molecules absorb that allow our eyes to perceive the color of the reflected light from the object. Color is really WEIRD when you think about it.

It's like that expression you've probably heard: any sufficiently advanced technology will seem like magic to those who see it the first time. All the wireless technology of recent years fits that idea very well.
What makes ZERO sense about cell phones is compression. The sound on copper land lines is awful. Why? Because the audio is compressed. That is done so that three, four, or more calls can be transmitted on the same line, without interfering with each other. It increased the number of calls a phone company could handle at any time. That made sense when we used land lines, but no on cell phones which are entirely digital. ALL CELL PHONES could have audio that sounds as good as a livestream video or a googlerooms/xoom chat, but phone companies STILL compress the audio for no good reason.
Much like radio & television. How sound and image can travel through the air in nano-moments and sound like what it's supposed to is not rational. Don't think about it to hard, your head might explode.

Why are clouds? How are clouds? What are clouds? Who are clouds?
Clouds exist for the same reason water condensation appears on a glass of ice water: water vapor in the air gets cold enough to make tiny water droplets. If enough tiny water droplets stick together, it makes bigger drops, like on the outside of your glass, or inside clouds. Clouds look white because water droplets bend light as it moves through the droplets. Some of the bent light reflects back (almost) toward the source of the light. When this happens in raindrops (which are much, much larger than cloud droplets) a rainbow may appear if you are standing between the sun and the raindrops. However, the smaller the water drops, the more the colors of light scatter in different directions, scattering even more as the light travels through more droplets. Clouds don't look like rainbows because the tiny droplets scatter the colors in every direction, far more so than raindrops do. If you mix all colors together you see white.
Moisture/condensation collected around tiny particles called "condensation nuclei" that are specks of dirt, dust or salt crystals, and that are too small to see with the naked eye. Once there are enough of these in one place, you see a cloud.

That the speed of light cannot be exceeded.
It is a finite speed, and yet nothing can go faster than that...
An Italian experiment has unveiled evidence that fundamental particles known as neutrinos can travel faster than light. Other researchers are cautious about the result, but if it stands further scrutiny, the finding would overturn the most fundamental rule of modern physics—that nothing travels faster than 299,792,458 meters per second. The 1,800-tonne OPERA detector is a complex array of electronics and photographic emulsion plates, but the new result is simple—the neutrinos are arriving 60 nanoseconds faster than the speed of light allows. "We are shocked," says Antonio Ereditato, a physicist at the University of Bern in Switzerland and OPERA's spokesman. https://www.scientificamerican.com/article/particles-found-to-travel/
And if we can go faster than the speed of light than that's time travel yeah?
Well, it could get silly. If you were able to travel faster than light, you could go somewhere, but you'd get there before the light illuminating your arrival is reflected by you arriving, so you'd be able to watch yourself arrive. Like i said, awkward.
Load More Replies...Personally, someday far in the future, I think we will discover that something, someway, can go faster than light; or maybe even figure out a way to speed up light. The real question is what happens to spacetime at that point. Like if light is going the max speed the universe can handle, it seems likely that spacetime would be causing the barrier. Like tachyons, which are theorized to go so fast (faster than light) that they travel through "time".
You may not go faster than the speed of light in a direct manner, but you can theoretically take shortcuts to skip ahead.

I don’t understand how we can see the Milky Way Galaxy in one spot in the sky. Why wouldn’t it completely surround us?
To clarify one point: The brighter strip of stars in the sky is often labeled the Milky Way, but the strip is just the brightest, most concentrated part from Earth's perspective. Almost ALL points of light in the sky visible without a telescope are in the Milky Way galaxy, too. The exceptions are the Moon, a few planets, a few nebulas (exploded stars), the two Magellanic Clouds, and the Andromeda Galaxy (if your sky is dark enough).
If you stand near the edge of a forest, you see thickets of trees in one direction, and a scant few in the other. It's like that, except that stars are hundreds of millions of light years apart.

But when you factor in lost efficiency and other things it's basically useless. But there's a small financial incentive for some companies and they lobby hard to keep us miserable
Solving equations using matrices. I can do other math, I don't like it and it makes my brain hurt, but I can do it. I tried SO hard to get past this part of Algebra 2, for multiple YEARS, and continually failed, to the point I gave up on college because I needed that math credit to graduate. I had 3 teachers, 2 tutors, a friend who used to tutor, and a loved one who was a high level software and hardware engineer, ALL try to help me through it. I'd get through the one problem they walked me through, and fail as soon as they had me try on my own. I never want to see another matrix. Except the movie series.
ETA: Guys. I appreciate the sentiment, but if the list of people who tried to help me didn't make it clear, you're not going to be able to solve this for me over Reddit. I don't need to solve equations with matrices to do anything in my life until/unless I try college again.
Matrix mathematics are a HUGE PITA (having done it in college), but it's absolutely necessary for many applications. GPS and air traffic control? Yup. Computer graphics and rendering polygons? Check. Systems of equations and statistics? Indeed.
Matrices was always difficult for me as well. I could do calculus no problem, but WTF is a kernel!
I passed higher grade Maths in Matric (I suppose the U.S. equivalent would be AP Math in 12th Grade) and I have never even heard of this. To be fair, I matriculated (graduated high school) in 1986.
I liked matrices because I was lazy. A matrix is a system of equations you can work on without having to write down the variables. (The columns organize the variables for you.)
Complex numbers are brilliant, especially when you need to solve equations describing the currents in electrical circuits.

Math taught my brain how to dance. Unfortunately, it never shared that information with the rest of my body.
Me and math got in a fight in 2nd grade and haven't spoken since. Thank God for calculators on my phone!!
Bluetooth and Wi-Fi. What is? How does it work? Is it real? Where does it come from? Like really, where tf does it come from!? I freak out about when I really try thinking if it. 😂.
Bluetooth, Wi-Fi, cell phone signals, and garage door openers all use radio waves. It's the same way an AM or FM radio station transmits radio waves, and you select an AM or FM radio station on your radio. The difference between all of those radio signals is how they choose to transmit information on those radio signals, which is called a protocol. For Bluetooth, Wi-Fi and cell phones, each device can both transmit and receive radio signals, but they all have to select which radio signals they use (how they know which to use is part of the protocol design). An analogy is if you walk into a room full of people and different groups of people are talking different languages. You might recognize a language spoken some distance away, even if others closer to you are speaking a language you don't know. Like you, computers can only use the languages (protocols) it knows about, and it ignores the rest.
First, I knew they were all electromagnetic radio wave signals like VHF/UHF TV and radio. Then I knew Bluetooth is actually invisible light waves! I am confused. Is WiFi 2.4 Ghz radio signals?
Bluetooth, like for headphones used with cell phones, uses 2.4 Ghz radio waves [https://en.wikipedia.org/wiki/Bluetooth]. It is possible that someone has developed hardware that uses light, but I haven't heard about it. There is no reason it wouldn't work with light. If you have several radio-based or light-based Bluetooth systems in the same room then they could interfere with each other to some extent. Radio-based Bluetooth is designed to be very low range, so Bluetooth devices in your neighbor's house will likely be undetectable. Infra-red and visible light travel through the atmosphere easier than 2.4 GHz radio waves, so light-based Bluetooth could interfere with other light-based Bluetooth devices at further distances. Most Wi-Fi uses the same radio frequencies, but Bluetooth and Wi-Fi are designed to be tolerant of each other. Microwave ovens in operation use the same frequencies in a noisy way (radio noise, not audio), and can reduce the usable range of Wi-Fi and Bluetooth.
Load More Replies... The whole cousins x times removed thing. I mean I kind of get second cousin once removed but beyond that it just confuses me. I have no first cousins. God I wish I had the gold star of cousins but I don’t. Instead genealogy websites are always trying to tell me that someone who was 73 when I was 4 is my first cousin but twice removed or some c**p. Hell no my parents were only children. They didn’t have some secret brother who was like 95 years older than them so get outta here with this is your first cousin but…c**p. Also don’t even with the but it’s different generations line of whatever. Why the heck was everyone in my family having kids at the wrong time?
Also does anyone remember that we’re related app Ancestry used to have where it claimed you were related to certain famous people? It told me George Washington is my First Cousin seven times removed. Yeah sure Jan and people don’t understand why I find this confusing. Not like I remember hanging out with him and Tommy Jefferson at the family camping trip.
If you share the same grand parents you're first cousins, the same great grandparents you're second cousins, the same great great grandparents makes you third cousins etc
And the "X removed" part is their kids relationship to you. So, my 1st cousins kids are my first cousins once removed (and a number for their kids and so on).
Load More Replies...I believe it. Particularly if you come from small, insular, communities that happened to have someone famous. Jews occasionally have those, being, generally speaking, small and insular. I think the leader of some obscure yeshiva in Belarus - or maybe Lithuania - was distantly related to me. The yeshiva was allegedly semi-famous.
I got a bachelor's in physics then worked in a geophysics research group. Did some grad school.
It took me until **30** to understand why it was colder at higher elevation.
Edit: I spent the last three days researching this, and I'm confident enough to say that all of the explanations here and the Google response are in fact **wrong**.
Temperature goes down *exclusively* because gravitational potential energy goes up. That's it. That's the entire ball game -- **energy conservation**. If you work out the math that's 10 degrees C per km.
The *actual* temperature decrease is 6.5 degrees per KM. This, I believe, is due to energy released by condensation.
Adiabatic expansion is a *consequence* of all of this stuff, not the *cause*. The *amount* of pressure and volume is a result of the energy lost to gravitational potential, not the cause of the energy loss.
While this explanation might be accurate at an abstract level, it ignores things like how sunlight increases surface temperature and the air above the ground, which rises. It also ignores how the temperature simply doesn't uniformly decrease with increasing altitude. See the graph on the right-hand side of the page here: https://www.noaa.gov/jetstream/atmosphere/layers-of-atmosphere
My understanding was that air density also comes into play. Less air to transmit heat or something?
Load More Replies...Nah. Ideal gas law tell us that as rising gas expands it will cool. Adiabatic conditions are rare. Most heating occurs at the surface, especially the land surface. Rising air can also lose heat to space.
Automatic transmissions. Those things are so complicated.
My mother refused to buy an automatic back in the '70s because apparently back then if it got out of gear (??) you had to try rocking it until it snapped back. I know lots of people with automatics these days and none of them even know what I'm talking about when I repeat what my mom said.

Imagine a piano that, instead of making an audio note when you press each key, the piano does different things for each key. Suppose this particular piano is designed for making food. You press one key, it measures out some flour. Press the key again and it measures out the same amount of flour again. Press a different key and it puts in some sugar. Another key adds butter, etc. Once you have completed adding your ingredients, you press another key which mixes the ingredients. Another key dumps the ingredients onto a pan, and another key selects an oven temperature, and another bakes your ingredients. The actions you performed on this piano are the same as following a recipe. If you make a machine that presses the keys for you to perform that recipe, that machine acts like a program, and the piano is the computer. The piano/computer is not smart. If your cat walks on the piano, you probably don't get good food. The person who built the machine/program is the only brains in the process.
I used to repair electronic digital music keyboards. One customer I had used an 88 note digital piano as a trigger for his subroutines. The digital piano sent out its code in Musical Instrument Digital Information, (MIDI) which has a separate code for each key. That "note on" code would trigger his computer to do a subroutine. I found out that he was one of the people who invented the 3D video software that does the computer generated video we now see everyday.

Even before Brooklyn 99 this was my answer - the Monty Hall Problem. And I’m actually fairly GOOD at math, this one I just can’t get myself to fundamentally understand!
Don't think of it as maths. Here's another way to help understand. if you make a random choice of three cards, one of which is an ace, you'll get the ace one time in three, on average, right? So the initial choice gives you a 1 in 3 chance of getting the ace, right? OK, now independently think of making a random choice from just two cards. The chances of getting the ace is 1 in 2, right? Now combine the two stages into the classic scenario, your first choice still has a 1 in 3 chance of being the ace, but on the second choice once a dummy card has been removed the other one of your two remaining card now has a 1 in 2 chance of being the ace. Keep the two stages separate in your head, choice of one card out of three, choice of one card out of two.
I still don't understand (and I'm usually pretty good at math). If you don't know for sure that your first guess is wrong, then isn't it still a 1 in 3 chance?

Sound. Vinyl records, recordings, phones. I mean, I can kind of get behind vinyl records. That makes the most sense to me but even then, that’s so f*****g intricate with so much variety. So many different songs with the tiniest little ridges that make millions of different results I come out perfectly just by dragging a needle across it. It absolutely blows my mind. But the technological advances of not only recording and playing audio, but also being able to do so in real time? No matter where you are in the world? It f*****g blows my mind like how does that work? How the f**k does talking on the phone work what kind of witchcraft is this.

Music theory.
I've played the piano since I was 5 years old. I read music and have known all the terms/etc. since I was a kid. Yet when I took music theory in college it kicked my butt! Mostly because a lot of it is like math, which I am terrible at. The circle of fifths nearly killed me. I can play and read music, but I doubt I'd ever be able to write it - my brain just has trouble grasping certain aspects of the theory.
Basic traditional music theory is very simple and logical. Much easier to understand when using a keyboard. Jazz music theory is like algebra. That is why all the best jazz horn players eventually learned keyboard theory. Much easier to visualize the note patterns and interconnections on a keyboard than the strange fingerings of horns like a sax.
"Basic" traditional music theory began long before the pianny, and pianny music theory is very far from basic. Don't let the linear layout fool you, and don't call it algebra - music theory has roots in geometry if you want to understand the patterns and interconnections.

It's basically a fee for all the amenities and services the government provides for you - roads, hospitals, schools, etc.
And the reason for a government is to provide the services that the private sector is unwilling to provide. Some of those needed services are protection from the greed and dishonesty of the private sector. If humans were basically good and honest, we would have no need for laws or law enforcement.

The rich are not paying their fair share and often no share at all. You are making up the difference. In my country, the people most likely to complain about taxes are the people most likely to vote for politicians who will perpetuate or expand this inequality.

Load More Replies... Affect vs. Effect
Please feel free to try and explain.
Look at the vowels; you'd expect Effect to be the vErb, but it's not. This is the rule I use and teach my students - works for some people to help remember. The inverse meanings (when effect is actually sometimes the verb and affect is sometimes the noun) are highly dependent on context, so wouldn't worry too much about them until you've got the basic meanings down 100%.
Affect is a verb meaning ‘influence or cause someone or something to change’, while effect is a noun that means ‘the result of an influence’. Here are some sentence examples: The heavy rain affected our lawn. It’s waterlogged! The loud noise from construction had a negative effect on my concentration. Lack of sleep can affect your productivity at work. The new medication had a positive effect on her pain management. The teacher’s absence affected the mood of the class. The decision to cut funding will have a significant effect on research projects.
It's literally just you are affected by an effect. eg: I am affected by poor vision. poor vision is the effect, and I am affected by it.
Affect is the verb. Effect is the noun caused by this verb... but keep in mind there is a verb "effect" as well (meaning "cause something to happen; bring about"). Isn't English wonderful?
'Affect' is a noun in psychology and music, where it means 'emotional tenor' (not Pavarotti).

It's the teachers job to explain things in a way that makes sense, or provide me a resource to figure things out, if I needed extra help I learned to ask whether it made the teacher happy or not. The younger students I went to college with were appalled I did this sometimes, but they appreciated it.
