What do we currently know about black holes?
Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can escape the powerful tug of a black hole’s gravity. Such a burst flings star matter out into space but leaves behind the stellar core.
What do we know about black holes in 2020?
Most black holes form from the remnants of a large star that dies in a supernova explosion. (Smaller stars become dense neutron stars, which are not massive enough to trap light.)…Recent Discoveries.

What is the beginning of a black hole?
One Star’s End is a Black Hole’s Beginning. Most black holes form from the remnants of a large star that dies in a supernova explosion. (Smaller stars become dense neutron stars, which are not massive enough to trap light.)
Are black holes real or just theoretical?
For a good time after Schwarzschild, black holes were purely theoretical. Or at least collapsed stars were, as they were yet to receive their more intriguing moniker. ‘Black hole’ is often ascribed to the American physicist John Wheeler, but its origins are shrouded in mystery.
How are supermassive black holes made?
Stellar black holes are made when the center of a very big star falls in upon itself, or collapses. When this happens, it causes a supernova. A supernova is an exploding star that blasts part of the star into space. Scientists think supermassive black holes were made at the same time as the galaxy they are in.
How do black holes affect the neighborhoods around them?
Recent discoveries offer some tantalizing evidence that black holes have a dramatic influence on the neighborhoods around them – emitting powerful gamma ray bursts, devouring nearby stars, and spurring the growth of new stars in some areas while stalling it in others.
