No matter how many all-nighters you pull devouring volume after volume of dust-laden encyclopedias, it will never be enough. Because learning is a process, and there’s no end visible on the horizon.
But most of us are just fine with one or two "did you know that?" facts always ready to be served at a dinner table. Except they get old fast and nobody wants to listen to another “banana is a berry,” like, ever.
Luckily, one Reddit user who goes by u/RyanBlitzpatrick did everyone a favor and asked people on r/AskReddit “What's a fact that just blows your mind?” 3.6K upvotes and 3.5K comments later, the results are in and you’d better get your notebook ready, 'cause these are some of the hand-picked knowledge bites that may honestly surprise you.

When you dream, one part of your brain is making up the story, and another part is experiencing those events and is genuinely surprised by all the twists in the plot.
2006, which doesn’t feel THAT long ago, saw the death of two colossally old tortoises. The first, Harriet, was reportedly collected by Charles Darwin when he visited the Galápagos on the HMS Beagle. She belonged to Steve Irwin at the time of her death. Charles Darwin and Steve Irwin shared a “pet.” Estimated to have lived 176 years.
The second, Adwaita, was born before the United States declared its independence from England. Think of it: just 14 years ago, there was a land creature alive that was older than our country. Just incredible.
November 2, 2000 was the last time all humans were on the planet together. Since then at least one person has remained on the international space station
I wish it was as easy to remember these facts as it was to scroll through. In reality, we do learn things every day, but not much of that information sticks with us.
But memory is a very complex function. It turns out, much of it is generated not only through recollection, but also through the emotions that are attached to it. Shahram Heshmat, a professor emeritus at the University of Illinois at Springfield, believes that “emotion affects all the phases of memory formation.”
For example, “Attention guides our focus to select what’s most relevant for our lives and is normally associated with novelty.” And nothing focuses the mind more than a surprise which escalates emotional intensity.
Martin Luther King, Jr. and Anne Frank were born in the same year.
Also, that same year, Betty White was already 7 years old.
The oldest living tree in the world methuselah is 4851 years old
That the Oxford Univeristy is older than the Aztec Empire
Another interesting thing which escalates long-term memory is not the recollection of a fact itself, but rather the so-called mood memory. Prof. Heshmat explains that “Our current emotional state facilitates recall of experiences that had a similar emotional tone.”
For example, being in a bad mood primes us to think of and remember unpleasant moments.Having said that, most of the things we forget easily have to do with our inability to put them in our long-term memory.
The sound made by the Krakatoa volcanic eruption in 1883 was so loud it ruptured eardrums of people 40 miles away, travelled around the world four times, and was clearly heard 3,000 miles away.
That's like you standing in New York and hearing a sound from San Francisc
If time travel were possible, you would need a time-and-space-machine to survive the trip, otherwise when you travelled back in time, the planet would be at a different point in its rotation around the sun and our solar system would be at a different point in space as it rotates, which means you'd travel back in time and be in an empty part of space
The International Space station is closer to the earth than San Francisco is to L.A
Meanwhile, forcing yourself to memorize things is likely not to be very effective because our brains are not capable of making sense of dense information quickly and forming strong associations.
It's better to use super simple tricks such as visualization (imagine what you are trying to remember), repetition (boring but effective), and learning the opposite things (create associations in your head).
And never underestimate the power of understanding that which you’re learning, because you'll never be able to remember something you can’t explain yourself.
Arctic foxes can survive temperatures as low as -70 degrees Celsius
If an underwater bubble is collapsed by loud sound, light is produced and no one knows why
Good. So next power outage I'm gonna fart in the tub and yell at it :D
Some people don’t have an inner monologue, like they literally don’t have a voice in their head.
I can't even imagine. Those must be the people who fall asleep easily!
A woman once jumped off the 86th floor of the Empire State Building but the wind pushed her back and she fell on a ledge on the 85th floor. She survived.
The fact that nobody knows that if we all see colours the same way
I think about that. It's more than just how you identify a color. There are colors in the aqua family I see as blue and my husband sees as green.
but what if he sees his green as your aqua? what if his green is actually your bright orange? we will never know
Load More Replies...Fun fact: language can shape the colors you perceive! There was a study done on people from various societies--one group was from a society with a very limited vocabulary describing colors, and another group was from a society that had a plethora of color names. When tested, the group with the limited vocabulary LITERALLY COULD NOT SEE more nuanced colors such as teal, vermilion, or saffron, while the group with the broader vocabulary was able to identify more colors than the average English speaker (our vocabulary to describe colors is actually quite average, but still pretty varied)
inuit do not differentiate blue from green, use word - note mixes in their embroidery etc.
Load More Replies...I see colors differently out of each eye.......my left eyes sees colors with a cool tone and my right eye sees things with a warm tone
That's actually really fascinating! Do you know if there is a reason behind it?
Load More Replies...This is so frustrating for me. I had a 35 minute argument with our Board of Directors over a design because two of them saw the plum color differently. I had to explain hex codes and Pantone formulas.
I have been wondering about that. If this is true, think about this: we may all have the same favorite color but we have just learned to call it different things.
Just because I'm curious, tell me what colors you see in those markers (I'm guessing). I see (going down from the top): black, red, purple, orange, brown, lime green, yellow, pink, green, and blue.
Same, though in my head I called the purple one lavender.
Load More Replies...Apparently we cannot really see magenta. We trick our minds into thinking we can. I still can't quite get that one.
Also, how you can never tell if someone is colour blind and you'll never truly know how they see the world...
Internal eye examinations can show if the 'rods', which detect color, are functional.
Load More Replies...I'd have to assume we do not. There are plenty of examples of perception differences, including that ugly dress from a few years ago.
I HAVE ALWAYS SAID THIS!! WHAT IF MY GREEN IS YOUR YELLOW... MIND BLOWN
I do paintings. I sometimes have people say that something should be a shade lighter or darker. I always answer...how do you know I havent lightened or darkened it, as no 2 people will see the same shade. Always makes people think!
Two of my sons are always correcting me about colours.... starting to think it is them.
Some people have 4cones and see millions of colors others don’t see.
Black, red, orange and purple, green and brown, yellow, pink, then another blue and green. That is what I see (from top to bottom in horizontal lines.)
I swear i had thought of it. Who could have proved what i see as red is the same red of someone else...
I think the way you see colours changes as you age. Flowers that I used to see as purple when I was a child, look bluer now I'm an older adult.
The wavelength of light doesn't change and neither does physics. We all see colors the same.
We may see them the same, but we interpret them differently.
Load More Replies...And if that's true about other humans, imagine what a load of caca it is when a "scientist" tells you how your cat or dog sees color!
TOTALLY NOT. There has been soooo many discussions with friends about colors, I'm pretty sure this isn't the case lol
I worked in a clothes shop and the guy who worked there thought that RED was one colour, i brought 14 RED clothes together from scarlet to maroon and yes to him they were red
We have the answer from people who have had multiple cornea transplants. The answer is that we do know: everyone sees a certain color a bit differently. Fun fact; one of these persons had (after a few transplants that were rejected after a few years) an artificial cornea and he felt he could see it was artificial.
If you are HSP, high sensitive person, many of them see colours more bright. I used to have a car, all called it grey, I saw it as light blue. I had many arguments about it. In my car papers I later found out it was a blue.
Yes, this fascinates me! All of our perceptions of color could just be a ~pigment~ of our imaginations!
I've often thought about that. Do we see the same blue sky when we look up?
We don't really :D There is for ex mutation in some women which makes them differentieta much more different colours then normal population. For ex https://www.nationalgeographic.com/news/2012/9/120907-men-women-see-differently-science-health-vision-sex/
Come to find out everyone's favorite color has been the same all along! lol
There are a lot of colors like burgundy for example that can seem like different colors to different people
The answer is NO. Just think of the colourblind people, or the ones who confuse them. Also, women see more detailed shades then men. Even our two own eyes perceive slightly different colours. (Shut one aye and look at something colourful, then try it with the other, several times- one might se slightly cooler tones than the other)
Just because we see many different tones doesn’t mean what you know as dark green can’t be what I know as light red
Load More Replies...well if that were true then there would be a lot of car accidents now wouldn't there
I know we don't, I'm graphic designer and see color very well, my 20 year daughter could look a 10 different shades of red and pink and only see red. She would say they all look the same.
That there are people in the world who don't like music. Not one specific type, but music as a whole.

I still can’t get over the fact that teddy roosevelt got shot and continued to give a three hour speech
Ant biologists still don't know the maximum life span of most ant queens. They just live too long to keep track, and they're not too easy to keep in captivity. The longest one on record is like 30 years old, and there could easily be species that live longer than that
There is a termite colony in the Amazon Rain Forest that is the size of Great Britain and is almost 4,000 years old. There are also hundreds of millions of termite mounds
The U.S government has an official for a Zombie apocalypse. CONPLAN 8888 also known as Counter-Zombie Dominance was written in 2011. And just in case you think it's weird bureaucratic humor, the first line reads, 'This plan was not actually designed as a joke.'
There are more trees on Earth then there are stars in the Milky Way galaxy.

If the timeline of the universe (up to now) was compressed into a year starting on new year's day, Homo sapiens would appear at 11:54 pm on December 31st
Mitochondria is only passed down by mother so there's a concept of mitochondrial eve, all humans today have their mitochondrial dna derived from her

The Fermi Paradox.
With the number of potentially habitable Earth-like planets in our galaxy alone, it’s very strange that we haven’t detected alien signals of any kind so far.
There’s lots of theories as to why that is, but my favorite is called the great silenceDark Forest (which sounds way cooler). Basically everyone else out there is being quiet and not transmitting because they know of some danger that we are unaware of, and they don’t want it to find them. Gives me chills.
Edit: It’s interesting that most of the replies here, joking or serious, correspond to legitimate theories on the Fermi Paradox.
That the biggest bacteria species known, Thiomargarita namibiensis, can have a maximum diameter of 0.7 millimeters, which is big enough for you to see it without a microscope.
That's insane if you consider that your average bacteria species has a diameter of 0.001 millimeters.

I already wrote this in a comment above, but I'm kinda worried it'll get lost in all the other comments and never be read... The most mind-blowing fact I can think of is from university (animal physiology lecture, topic visual sense). There's a small experiment that shows you how crazy much your visual input is curated before it ever reaches your consciousness, in a way not other experiment ever made that clear to me: Take a flashlight, point it sideways at your eye (as in, hold it by the side of your head and point it at the nose so you eye is hit sideways), then wave it about. Then sit in stunned silence. The sensory cells don't actually detect light as such, but a CHANGE from dark to light, so cells behind blood vessels never report anything. Until you wave a light about from sideways, that is... (my other favorite weird fact from that lecture is that "penis fencing" is an actual zoological term. Flatworm mating.)
I tried it out, it's so weird O-o. There's another cool thing worth mentioning is that everything we see is in the past. It takes time for light to travel from our eye to an object and then back while also processing the image so even if that time is minimal, we only see what has already been. Same with sound. When someone speaks, it takes time for the sound the travel so we never really hear a person speak in the present, but what they said in the past. AND this includes interactions. There is a concept of space-time where each person, wherever they are standing, is their own form of "present." When I am speaking and looking at someone right in front of them, I am actually communicating with their past selves, not the present. The only way for us to be in the same "present" is when we hug :3 (amongst other touchy interactions)

If you wrapped a belt around the equator, how much length would you need to add so the belt would be 12 inches off the ground for you to crawl underneath? The answer is 6 feet would need to be added, yes just 6 feet. 25,000 miles around and only 6 feet make that big a difference.
The Universe is 10 ^ 26 meters in diameter. Atoms are 10 ^ -15 meters in diameter. -- Quarks are 10 ^ -19 meters. Humans are just a bit closer to the size of atoms and their components, than we are to the size of the Universe. -- We're really not that consequential after all, but we do kinda straddle the middle point between atoms and the Universe, size-wise.
