Answer:
Step-by-step explanation:
In general relativity, there are two types of black holes:
1. Stellar black holes: These form from the collapse of a massive star. Stellar black holes typically have masses ranging from a few to tens of times the mass of the sun, and they are the most commonly observed type of black hole.
2. Supermassive black holes: These are much larger than stellar black holes and are thought to exist at the centers of most galaxies. Supermassive black holes can have masses ranging from hundreds of thousands to billions of times the mass of the sun.
It is possible that there may be other types of black holes beyond these two categories, but they would be purely hypothetical at this point and would require new physics beyond General Relativity to describe them. For example, there is a hypothetical type of black hole called a primordial black hole that could have formed in the early universe, but they have not yet been observed. So, in summary, there are currently only two fundamentally different types of black holes that are expected to exist based on our current understanding of physics.
