Question

what is black hole and its feature​

Answer 1

Explanation:

1. Black hole are formed when stars with more than 3 solar mass die and all the mass of that star enters into a small dense point. Now, there are 2 parts in black hole, Event Horizon and Singularity. Event Horizon is just the curvature in the fabric of spacetime. Singularity have 2 definations, singularity may be infinte small and dense with extreme or near infinite mass or it may be extreme dense and mass and it can connect to another universe . The bridge formed by the black hole which connects to another universe is called Einstein-Rosen Bridge. The gateway that opens in another universe is called a white hole. However any of these theories about singularity and whether black hole connects to another another point in universe is not yet proved. Famous physicist Stephen Hawkings claims that black hole can evaporate slowly by producing hawking radiation. Einsteins special Relativity claims that time passes slowly near a black hole as we will revolve very fast around a black hole. Black hole sucks everything even light! Thatswhy black holes are black.

Answer 2

Answer:

A black hole is a region of spacetime exhibiting gravitational acceleration so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole....
