Can anything escape from a Black Hole?

Asked by blueiiznh (16658points) February 17th, 2013

When a mass as large as the sun is compressed into a ball a few kilometers in diameter, can anything that gets pulled into its close radius and gravity ever escape?

No, supposedly everything gets sucked in to it’s mass.

No, nothing could ever escape, not even light. The only thing that can “escape” from a black hole is Hawking radiation, and that actually involves negative energy falling into a black hole. Hawking radiation will eventually destroy the black hole.

Yes, in the form of Hawking radiation, also known as evaporation.

Nope, not even Superman . . .

I don’t know. Still trying to figure out if we’re on the outside, being pulled in, or the inside, being sucked out.

I get the feeling that a black hole is actually the end of a giant straw, sucking out the last spittle in a universe sized slurpy cup.

Once you in, you’re probably screwed, but according to scientist you my end up in another dimension.

I expect; in a very special physical condition, dark matter can escape from black holes. Others than that can not.

As I understand it, there’s a Point Of No Return – up until there, you might have the energetic wherewithal to escape.
Not entirely certain, but I think Sol’s too small to collapse into a black hole.

No, the sun really isn’t large enough to collapse into a back hole, at least by its own means. If it were compressed, however, into a small enough space, then it would form a black hole. The problem is that it is too small for it to compress itself.

Most black holes form from much larger stars – hundreds of times larger than our sun.
