Explanation:
A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can't see black holes.

Answer:
A black hole is basically a dead star
Explanation:
A star has gravity. Due to nuclear fusion energy is released which balances gravity. when gravity wins against all other subatomic forces such as repel of electrons and others it collapses into an infinitely dense point.
Although black holes have a lot of gravity.
I recommend you see the youtube video from kurzgesagt about black holes. Kurzgesagt is a great educational youtube channel
