Micro black holes are, as their name implies, very tiny. They might have perhaps only 20 micrograms of mass. In both cases, the mechanisms for their creation are not entirely clear. Micro black holes exist in theory but have not been directly detected. Supermassive black holes are found to exist in the cores of most galaxies and their …reproduce the entropy of all black holes, but this argument does not reproduce the entropy exactly. Recently a precise calculation of the entropy of a neutral black hole in string theory was achieved (Emparan and GH, 2006).

While black holes are mysterious and exotic, they are also a key consequence of how gravity works: When a lot of mass gets compressed into a small enough space, the resulting object rips the very fabric of space and time, becoming what is called a singularity. Apr 8, 2021 · Despite the lack of insight into the innards of a black hole, physicists do know that black holes exist. The first evidence came in the form of Cygnus X-1, a bright source of X-rays about 6,000 ... Black holes are formed when giant stars explode at the end of their lifecycle. This explosion is called a supernova. If the star has enough mass, it will collapse on itself down to a very small size. Due to its small size and enormous mass, the gravity will be so strong it will absorb light and become a black hole. Yes, black holes emit a little amount of radiation called Hawking Radiation (named after the discoverer). This radiation comes directly from the black holes mass and the black hole slowly gets smaller overtime. This takes an extremely long time though. The average stellar black hole will take an incredible 10^66 years to decay (10 with 66 zeroes).
