black holes?

There are several types of black holes, the most important of which are stellar and supermassive black holes. Stellar black holes, as their name implies, arose from a star (Latin: stella). More specifically, from a massive star, which at the end of its life, when it runs out of “fuel”, becomes a supernova. The heart collapsed into a black hole. Stellar black holes have a mass of 5 to 100 times the mass of our Sun.

But there are also supermassive black holes. They have a mass of at least 5,000 times the mass of the Sun to millions of times the mass of the Sun. They are found in the middle of galaxies.

At the center of the black hole is the so-called singularity, a pointless point of infinite density and extremely small size. The gravity here is so strong that space-time is infinitely curved.

Some distance from the singularity is the event horizon, the ‘event horizon’, from which nothing can escape until one cannot perceive what is happening behind it. The event horizon is the “point of no return”, and everything absorbed by gravity can no longer escape, not even light. This is why a black hole is black, it does not emit any form of electromagnetic radiation, and therefore there is no light.
