Question

hi guys what is known as black hole, how it occurs, by the way happy pongal to all guys

Answer 1

Most black holes form from the remnants of a large star that dies in a supernova explosion. ... However, as the star collapses, a strange thingoccurs. As the surface of the star nears an imaginary surface called the "event horizon," time on the star slows relative to the time kept by observers far away.

Answer 2

By the way black hole is a phenomenal occurrence

Black holes form when a massive star can no longer produce energy in its core. With the radiation from its nuclear reactions to keep the star "puffed up," gravity causes the core to collapse. The star's outer layers may blast away into space, or they may fall into the black hole to make it heavier.
