Princeton physicist John Archibald Wheeler coined the term in the 1960s. Back then, black holes were theoretical so the name was fitting for the lack of evidence we had on them.
I watched Interstellar and still have multiple questions after watching it, but I always wonder if you were sunk into the black hole, where would it take you? Or does one die?
Answers vary with this question. In theory, you would end up in another part of the universe after passing through an event horizon, but the general view is you would be crushed before you could pass through since everything that enters the structure would be compressed into one point in space. But, more hopeful theories include a back door that would take you to another part of the universe, as I said before.
Well mass is the amount of matter in an object, and when matter enters a black hole it is warped or broken down after crossing the event horizon. So, mountain sized matter in an atom-sized black hole is a relative size when placed on a scale of possible black hole masses. And these masses are usually determined by how fast objects around a black hole orbits them.
If you were to walk into a black hole, the front of your body would feel much more gravitational pull than the back of your body. You would then be stretched further and further until you were just a stream of subatomic particles. So if the black hole were about the size of Earth and you walked into it, it wouldn't take much time for that gravitational force to dissociate your organs into their constituent atoms and that's how you would bite the dust.
We cannot see a black hole, for even light cannot escape. However, we can see the objects moving toward or orbiting a black hole and that's how they're discovered.
Two black holes could absolutely collide if they were to come so close that they couldn't escape each other's gravity. This collision would then form an even bigger black hole.
If a black hole traps something like a planet does that add to their mass? What happens to the mass of the thing that is now a part of the black hole Tyler Silk
Yes, this would add to the black holes mass. The mass of the object that enters the black hole would decrease as it further enters. The matter would then be stretched until it was a stream of subatomic particles.
You could not see anything that has entered a black hole, at least not with a human eye. All matter that enters is broken down to subatomic particles. Even though light has no mass, it cannot escape a black hole because the gravitational force within the black hole bends the light further and further into it so it is impossible for it to escape.

You said that time slows down the closer you get to the black hole. How much slower does time slow down?
ReplyDeleteThe time dilation depends on the gravitational field. The stronger the gravitational field, the greater the time dilation effect.
DeleteWhere did the name "black hole" come from? How does this relate to the structure and function of a black hole?

DeleteWill earth or any other planets during their existense make their way to an event horizon and be sucked into a black whole?
ReplyDeleteIt is definitely possible but you'd probably have better odds playing the power ball to be honest, so I wouldn't worry too much.
DeleteI think it's quite fascinating that a black hole can be the size of an atom and have the mass of mountains. How is this so?

DeleteHow dense does something have to be in the black hole for light or to see something inside the black hole?
