: I'm not sure who I'm sending this to,nor who will respond!My question is what happens inside a black hole?I have read it is gravity pulling in everything within 1000 miles, but what happens to these objects? Does gravity crush the atoms and so on so forth?Is there another side to this or is the black hole something of a ball in space?Im very curious to know what this is all about!Is the earth safe from black holes?Is there a possibility that the earth could someday become a black hole itself? Thanks for your time and I will be waiting to hear your response to these questions!

The theory of the interior of a black hole is weak, but under strong gravitational field, atoms can be crushed. Black holes are spherical in shape. It is theoretically possible for the earth to encounter a black hole eventually, but there aren't any nearby (gravity would tell us if there were). The earth is too small to become a black hole. The minimum mass required is about 1.4 solar masses. A large star can become a black hole after all the fusion fuel has burned out and the supernova blowoff is complete.
