Strange Hole Spans a Billion Light-Years + 30 Hypnotizing Space Facts

our son is an average size star and still it could fit one million 300 000 Earths the star is also 333 000 times as heavy as our planet NASA has translated radio waves created by planets atmospheres into audible sounds that's how astronomers found out that Neptune sounds like ocean waves Jupiter like being underwater and Saturn's voice resembles background music to a horror movie here on Earth it's Bebop Jazz now I made that up the sun surface is scorching hot but a bolt of lightning is five times hotter Earth gets dropped by 100 lightning bolts every second which results in 8 million lightning strikes a day and around 3 billion a year ooh shocking if you manage to go to the Moon one day and see fresh footprints that doesn't mean there's someone else there with you Footprints or similar marks can last for a million years over there because the moon doesn't have an atmosphere there are no winds not even a breeze that can slowly erase those footprints astronomers have found the largest hole we've ever seen in the universe it's the giant void that spreads a billion light years across they found it accidentally one of the research team members was a little bored and wanted to check how things are going in the direction of the cold spot that's an anomaly in the cosmic microwave background map or CMB for short it's a faint glow of light that falls on our planet from different directions and fills the universe it's been streaming through space for almost 14 billion years as the Afterglow that occurred after the big bang so you fall right into the heart of the black hole and prepare for a sad end well you don't have to falling into a black hole won't necessarily destroy you or your spaceship you have to choose a bigger black hole to survive if you fall into a small black hole its Event Horizon is too narrow and the gravity increases every inch down so if you extend your arm forward the gravity on your fingers is much stronger than on your elbow this will make your hand lengthen and you'll feel some discomfort rather significant to be honest things change if you fall into a super massive black hole like the ones in the center of galaxies they can be millions of times heavier than the sun their Event Horizon is wide and the gravity doesn't change as quickly so the force you'll feel at your heels and at the top of your head will be about the same and you can go all the way to the heart of the black hole this myth is busted if you watch a very touching movie in space and start crying your tears won't run down they will gather around the eyeballs your eyes will get too dry so you'll feel like they're burning any exposed liquid on your body will vaporize including the surfaces of your tongue speaking of burning that's one thing fire can't do in space fire can spread when there's a flow of oxygen and since there's not any in space well once they explode Stars aren't supposed to come back to life but some of the Stars somehow has survived the great Supernova explosion such zombie stars are pretty rare scientists found a really big one called LP 40 365. it's a partially burnt white dwarf a white dwarf is a star that burned up all of the hydrogen and that hydrogen was previously its nuclear fuel in this case the final explosion was maybe weaker than it usually is not powerful enough to destroy the entire star it's like a star wanted to explode but didn't make it which is why part of the matter still survived if you ever go into space don't take off your spacesuit unless you're on a spaceship air in your lungs would expand as well as the oxygen in the rest of your body you'd be like a balloon twice your regular size good news the skin is elastic enough to hold you together which means you wouldn't explode small comfort when something goes into a black hole it changes shape and gets stretched out just like spaghetti this happens because gravitational force is trying to stretch an object in One Direction but at the same time squeeze it into another like a pasta paradox speaking of a black hole that's as big as a single atom has the mass of a really big mountain there's one at the center of the Milky Way called Sagittarius A it has a mass like for a billion Suns but luckily it's far away from us home on an asteroid you'd never be able to hear its loud sound yes we often hear the sound of spaceships and battles in space in the movies but that's just a myth sound is a wave that spreads because of the vibrations of molecules a person claps a few feet away from you the sound wave begins to push the first air molecule next to the clap then the second third and so on until the wave reaches your ear so to spread sound we need molecules like air or water in our atmosphere sound waves spread out just fine but space is a vacuum so it's nothing here you can clap your hands loudly there but there just won't be any molecules that can vibrate and carry that sound so to carry on a conversation you'd either need a radio or really good lip reading skills meteoroids orbit the sun while the majority of human-made debris orbits our planet for example we launched almost 9 000 spacecraft around the world from satellites to rocket ships even the tiniest pieces can damage a spacecraft at such high speeds galaxies planets comets asteroids Stars space bodies are things we can actually see in space but they make up less than five percent of the total universe Dark Matter one of the biggest mysteries in space is the name we use for all the mass in the universe that's still invisible to us and there's a lot of it it may even make 25 percent of the universe Dark Energy makes the other 70 of the universe hmm that adds up to a hundred right now let's look at the Moon it always looks at us with one side this means the moon has a dark side and the sun's Rays never get there well that's a myth the whole point is that the Moon is gravitationally locked to the Earth there are days and nights there too it's just that this rotation is perfectly aligned with the rotation of the earth so whenever you look at the Moon you only see one's eye although there are days when the sun shines there too so it's not the dark side it's the far side and we even have pictures of this place and there's one of the biggest craters in our entire solar system the South Pole Aitken Basin is as wide as two states of Texas yeehaw one myth that turned out to be untrue is that people have never actually been on the most this is the original spacesuit of the first astronauts who were there look at the soul of the shoe some people claim there's no way they could have left Footprints like this there actually they could on the moon the astronauts wore extra boots over their suits and their souls matched the footprints on the moon perfectly now the astronauts didn't need them when they left the moon and tossed them when the moonwalk was over they left a lot of stuff there too they even tossed the armrests of the seats in the lunar module to reduce the weight now counting all the Apollo lunar missions the total weight of rubbish on the moon is approximately 187 tons including several lunar Rovers spacecraft debris six lunar modules and all the experiments left behind that's like three Boeing 737s another myth about the sun is that a cello let's send you into space for this one you look out the window and it's white the sun only appears yellow to us through the filter of our atmosphere the composition of the air and its thickness just distorts the light of the star but stars do come in different colors cooler stars have bright orange and red colors these are usually very old stars older than our sun but young and very hot stars are bright blue the sun is about in the middle of this spectrum oh one more myth about asteroids we need to fly a little farther than Mars's orbit whoa we're in an asteroid belt and we constantly have to dodge giant rocks and blocks of ice we got in some dense asteroid clouds not true the fact is that space is huge and the distances are incredible all the rocks and debris in the asteroid belt are only four percent of the weight of the Moon so there really aren't that many of them there to understand the dimension of The Emptiness in space look at the Collision of two galaxies there are billions of stars in each of them if we mix them up it's unlikely there will be any collisions even here that's it for today so hey if you pacified your curiosity then give the video a like and share it with your friends or if you want more just click
