This is for a school project and Im sorry that Ive been away for like two years XD
https://www.nasa.gov/audience/forstudents/5-8/features/nasa-knows/what-is-a-black-hole-58.html “Stellar black holes form when the center of a very massive star collapses in upon itself. This collapse also causes a supernova, or an exploding star, that blasts part of the star into space.” https://kidsastronomy.com/the-universe/black-holes/ “Now, you might be wondering: If we can’t see black holes, how do we even know they’re real? To be clear, we didn’t know for sure until just a few years ago. Astronomers could prove mathematically that they should exist. But, they had no direct evidence of them. There was one particular thing they kept looking for, but couldn’t find. That thing was the existence of what are called gravitational waves. In 1916, the famous physicist Albert Einstein predicted the existence of these waves. He said that they would be given off by the collision of very massive objects. Two, colliding black holes obviously qualify. Still, we weren’t able to observe these waves for a very long time. That changed in 2015.” https://www.space.com/3452-black-holes-dark-deadly.html “The ones that we know about are rendered visible because they happen to be next to another star where they orbit each other in space and that other star in many of these cases is losing its outer gaseous material. In a way it's getting flayed by the gravity of the black hole. And as the gas spirals down, kind of like water down a toilet bowl, or when you pull the drain on any body of water, you see the water begin to circle and as it goes down the hole, the gas from the nearby star does that too. As it spirals down, it begins to glow just before it's lost forever in the black hole. So we see glowing gas that has been removed from nearby stars so that's kind of like the smoking gun that there's a black hole there. All the ones we know about that are scattered around the galaxy are made visible to us by this process.” https://science.howstuffworks.com/science-vs-myth/what-if/what-if-black-hole-formed-near-solar-system1.htm “All through your approach, time would have slowed -- a lot. From your point of view, nothing would have changed but, to a friend watching from far away, time around you would flow less like greased lightning and more like sap on a cold February morning. Just outside the event horizon, you would appear to stop. Since light cannot escape the event horizon, that would be the last your friend would see of you.” https://science.nasa.gov/astrophysics/focus-areas/black-holes a black hole is anything but empty space. Rather, it is a great amount of matter packed into a very small area - think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City. https://www.nasa.gov/centers/marshall/news/news/releases/2014/14-169.html The giant black hole at the center of the Milky Way may be producing mysterious particles called neutrinos. If confirmed, this would be the first time that scientists have traced neutrinos back to a black hole https://www.space.com/40422-are-white-holes-dark-matter.html White holes, which are theoretically the exact opposites of black holes, could constitute a major portion of the mysterious dark matter that's thought to make up most of the matter in the universe, a new study finds. While reviewing another physicist's solution to the equations in Albert Einstein's theory of general relativity, Austrian physicist Ludwig Flamm realized another solution was possible. He described a "white hole," a theoretical time reversal of a black hole.- Space.com white holes https://www.space.com/20881-wormholes.html https://www.spaceanswers.com/solar-system/what-would-happen-if-a-black-hole-entered-our-solar-system/ An incoming black hole would be invisible until it sucked material from the planets to give it a glowing accretion disk.How likely is it that a black hole could enter the Solar System? Well, you’d have to define likely; it is more likely that the Earth will get swallowed by a black hole than, say, winning the lottery ten times in a row, but less likely than being struck by lightning. In fact the odds of a black hole devouring our planet are estimated at one in a trillion. There are two predominant types of black hole in the universe. The first are supermassive black holes found churning at the centre of galaxies. These don’t really pose any threat to us, until our galaxy collides with another like the Andromeda galaxy in a few billion years. https://www.universetoday.com/46687/black-hole-facts/ Like creatures behind a cage, it’s okay to observe a black hole if you stay away from its event horizon — think of it like the gravitational field of a planet. This zone is the point of no return, when you’re too close for any hope of rescue. But you can safely observe the black hole from outside of this arena. By extension, this means it’s likely impossible for a black hole to swallow up everything in the Universe (barring some sort o
