What Remains Inside a Black Hole was created in 1996.
No. No planet is massive enough to become a black hole. A black hole is the remains of a dead, supermassive star.
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.
A black hole is the stellar remains of a massive star.
Nothing can escape from a black hole.
Impossible.
