All the matter that collapsed into the black hole, as well as any matter that fell into the black hole after the initial collapse. The only distinguishable part of such matter is its mass - any structures of matter, even atoms, get destroyed.
What Remains Inside a Black Hole was created in 1996.
Nothing can escape from a black hole.
No you really cant walk inside a black hole, you only float then you die shortly
It disappears forever
No, they are not the same. A singularity would be inside a black hole.
For all scientific reasons, no astronaut had went inside a black hole. It would take many earth years to visit the black hole, so reaching a black hole is impossible.
no
No.
It is impossible to know what is present inside a black hole, though it is theorized that a singularity is located at its centre.
A black hole can't really form inside of another black hole. If you think of a black hole forming after a star goes supernova, then there isn't really a star to go supernove inside of the already created black hole. In fact, there isn't even any space inside of the blak hole for anything to happen. Two black holes can join together, but they wil eventually go to one.
At the center of a black hole is a mass that has collapsed to an infinitely dense point.
You can't, if you call it in the black hole being inside the event horizon; that is if you mean inside the 'black' portion of the hole. If you say near the black hole, then it depends on how close and how much thrust, fuel and mass your ship has.
