According to NASA:
“A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can’t see black holes. They are invisible. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently than other stars.”
So, considering black holes are so strong that not even light waves can escape, what would happen if Earth itself ever got too close and was sucked into one?
Take a look at BBC Earth Unplugged’s video explaining what would happen to our little planet if crossed paths with a powerful black hole
You die. Well, that would be pretty obvious, but the moment before you die something pretty *bad* happens. Spaghettification.
Even when near a stellar black hole, the gravitational pull near your feet can be a million times stronger than at your head, and you guessed it. You get stretched like a noodle. It’s a horrible way to die.
Now, if you wrote this question keeping in mind this scene, then let me clear up things a bit more
That’s the supermassive black hole Gargantua from Interstellar. Why didn’t Cooper die of Spaghettification when he was falling in? In a supermassive black hole (like Gargantua), the singularity (the point where gravity becomes infinite), is quite far away, contrary to a stellar mass black hole. The closer you are to singularity, the more chances of getting spaghettified right away. Gargantua was massive.
What was with the 5D bookshelf inside it? That’s another story. Because no one knows what happens inside a black hole. Or you might say
