Why do a star make a black hole.? ( Not How ).?

Question

think you know?

Answer 1

it compresses itself then collapes into itself creating intense gravitational pull

Answer 2

Stars are "held up" by internal pressure. The pressure can come either from thermal energy, or from "degeneracy pressure", which results from the quantum mechanical rule that no two fermions can share the same state. A star that has more than about 1.45 solar masses and a (relatively) low internal temperature does not have enough pressure to hold itself up, no matter what. It therefore collapses, and once the surface is near the Schwarzshild radius, it becomes a Black Hole. One thing that helps drive the collapse is that gravitational force is a source of gravity, so the more it collapses the stronger the gravity becomes.

Answer 3

The writings of Stephen Hawking should answer most of your questions about black holes. Show people that you have learned from previous questions that you have asked about black holes by including information in the question details, or why it is relevant.

Try choosing a best answer yourself, instead of leaving it to a vote. This will mean actually reading the answers given. You can learn a thing or two.

Answer 4

If a star makes a black hole, it does so because it has no choice. Just like a rock in your hand falls to the ground when you let go; it has no choice.

Answer 5

why? that is because the laws of physics says so. only stars of a large mass form black holes. they run out of fuel and thus outwards pressure and therefore they collape indefinetly into nothing but a large center of gravity.
