Consider this a sister thread to the 'random history facts' thread. Along with history, I deeply enjoy science. So, I'd love to know any interesting facts you guys have related to science, any science, expanding my and other's knowledge! I'll start. Eyesight affects balance- if you try to stand on one foot with your eyes closed, you'll most likely start to topple over. But stand on one foot with your eyes opened, and you can stand much easier. The fleshy part of the eye close to your nose was originally a third eyelid humans have. Of course, we evolved out of it- but that part is the remnant of that eyelid. The Platypus has a venomous 'thumb'. Believe it or not, bones are a lot stronger than you think. Bone is literally stronger than steel.
I've got a few. - Scientists still aren't 100% sure why ice is slippery. There are many theories, such as ice actually being suuuper high friction, so high that any object moving along it generates heat of friction enough to melt a tiny bit of ice into liquid water which is in turn slippery, but none of these are proven and it's still a mystery. - Time travel has been proven to be possible. Difficult, but possible. A mass with negative energy (which is an actual thing, not just my plan-b for a username) will actually move through the 4th dimension in the opposite direction as its surroundings, thereby moving backwards in time. - There's a reason most people don't recognize the sound of their own voice: it's because you actually have three voices. There's your mental voice (the one you probably hear in your head right now unless you've heard me speaking before, in which case I would have a Morgan Freeman effect on you); the voice that you hear as you speak which mostly travels through flesh and bone to your ear (affecting its sound wave transmittance, which is different than if it was moving through air); and your external voice, which is the one heard by microphones and voicemails and the people around you. Unless you make a point to listen to recordings of your own voice, you probably never actually hear it, and when you do, it sounds like an uncanny impostor imitation of your voice in your mind and transmitted through your skull: creepy, unfamiliar, and uneasy. - A few months ago, medical scientists found a new organ in the human body, and it's perhaps the largest organ. How does the largest organ go unnoticed through millennia of medical science? It's kind of like how the plumbing or electrical system of a skyscraper is as large as the skyscraper itself: this new organ, the "interstitium" is a structural/transport part of the body that is in turn part of every other part of your body, head to toe, which means it's as big as you are and nobody ever knew it was there. About Junkrat's third-eyelid mention, if you're confused as to what that would be like, look at the eye of a house cat who's asleep with its eyes slightly open, or a crocodile as it's dipping into or out of water. Cats have a white part near their medial canthus that kind of extends over the eye if it's closed too long, and crocodiles have a barely-transparent layer that also emerges horizontally so it can sort-of see while underwater. It makes me wonder if Aquaman has a useful third eyelid of the same kind.
I'm not completely sure whether or not this is true (If it doesn't then tell me), but I've heard that planets like Venus and Uranus spin the opposite direction and therefore because they are one of a few planets that spin backward it disproves the Big Bang Theory Then there is another theory that states that the Earth isn't millions of years old because if it was then the moon would have been so close that all the tall dinosaurs that we know and love wouldn't have existed. These theories are interesting if they are proven to be true but I really don't know much about science so what do you guys think?
Weirdly enough, it's only the male platypus that's venomous. Speaking of venom, for the longest time Komodo Dragons were referred to as "poisonous" instead of "venomous" because it was thought the bacteria in their saliva was what poisoned their bite victims instead of a venom they produced. A few years ago it was apparently discovered that Komodo Dragons DO produce venom. It's typical for planets to rotate in the same direction as the sun they orbit, but the direction a planet rotates in also depends on the tilt of its axis, which can change if hit by another large space object. I'm not entirely sure how that would disprove the big bang theory. I'm not entirely sure what that second theory even means. Technically the Earth isn't millions of years old, it's 4 and a half billion years old. So if that's supposed to prove how old the earth is/disprove creationism, I guess there's something to it? It kind of sounds like it means that tall dinosaurs would hit their heads on the moon though. Although if the moon was closer to the earth, you would think the stronger gravitational pull would actually make things taller. I don't know, that wording just isn't very specific.
Oh yay, I love trivia stuff like this! And I'm not going to post it without aviation stuff in here! Apparently, you are more likely to survive a grenade blast on land than underwater. Water amplifies explosive crushing power that can liquefy organs. An ounce of gold can be made into a 50 mile long wire. The wingspan of a Boeing 747 is longer than the distance of the first flight by the Wright brothers. One single 747 engine (there are 4 total per aircraft) will burn more than a thousand liters of jet fuel an hour. That's enough to consistently fuel a family sedan for half a year. Oh and while most flights have all engines operating while in-flight, every multi-engine aircraft flying today is capable of operating on one engine if necessary. Those 4 engine aircraft are tested inflight flying on one engine (sometimes one at a time!) When you see a spider on a web, it actually weaves two different sides. One is a non-sticky side in which it crawls upon and the sticky side where it traps prey. If the spider were to touch the sticky spider, it would stick just like anything else. Spiders also recycle their webbing, so it will simply eat its way out of a web if it gets stuck.
Welp...I'll go into as much detail as I can. About SPACE! Did you know, that stars generally from around 120-0.08 solar masses (times the mass of our sun), but the most common type of star are those less than one solar mass while the most luminous are those larger than one solar mass. The first exoplanet was discovered around 1996. That's right, we didn't even know if planets existed outside our solar system 25 years ago. The most common type of exoplanet (other than a hot Jupiter) are Super-earths/mini-Neptunes. These are generally just as the name implies, really large earths. Some are even so large, that they can hold helium in their atmosphere. Its not talked about much, but a European space agency sent a rover to a comet. It landed right in the perfect spot...then bounced...then bounced again. It bounced across the surface three times before landing upside down under a shaded rock. It was lost pretty quickly and the rover never got up again. Comets have two tails, the gas tail and the particle tail. Scientists are still unsure about where the moon came from. They think it came from a huge mars size asteroid that hit the earth (gave the core nickle), and spewed so much material into space that it formed a ring, then a moon. They think this is where the moon came from, but they can't be sure without a time machine. Did you know there a ton of gold on earth. Why haven't we found it? The thing is, gold mixes with iron when melted...thus all the gold is in the core. In fact, the entire core is purely made up of elements that mix with iron when melted. Most of the elements are right in the center of the periodic table but surprisingly, silver isn't one of them. In an ungodly amount of time, eventually the expansion of the universe will move faster than light. When that happens, we wont be able to see stars anymore, it'll just be blackness. Dark matter. We don't know what it is, but its there. And that just about explains atomic physics. Do you know why the earths core is so hot? Easy, Uranium decay. Okay maybe not easy but most of the heat in the solar system actually comes either from the formation, or some sort of isotope decay. For earth, I believe its mostly Uranium. Uranium decay is also how we have helium on our planet. We can't naturally have helium because earths too small and all the helium left earth a long time ago. I could go on, but this list is already quite long. Look to the future, I might post more interesting science facts. Or at least I think their interesting.
instead of just listing what i just recently learned science-wise, it's much more helpful to just post a video about it here: Who knows that such bacteria could actually be really helpful?
There is no such thing as "organic"/"all-natural" papayas/bananas. The original species for both of them were decimated by plant diseases and we had to genetically modify them to keep them from going completely extinct.
