It is not. A black hole is an object in space, the universe is not.
Those questions do not even make sense.Jim Stanley said:
While there is currently no definitive evidence, there are some interesting similarities between black holes and the universe. For example, both have an event horizon and are surrounded by an infinite amount of mass. However, more research and observations are needed to confirm this theory.
If the universe was a larger version of a black hole, it would mean that our understanding of the laws of physics would need to be revised. It could also have implications for the fate of the universe and the possibility of traveling through space-time.
Theoretically, it is possible for a black hole to become a universe, but it would require a significant amount of time and mass. Additionally, it would need to avoid evaporating through Hawking radiation, which is currently only a theoretical concept.
The idea that a black hole is a singularity, a point of infinite mass and density, is a key component of the theory that the universe is a larger version of a black hole. It suggests that the universe may also have a singularity at its center, which could potentially explain the expansion of the universe.
Gravity plays a crucial role in the theory that the universe is a larger version of a black hole. It is the force that holds matter together in a black hole and is also responsible for the expansion of the universe. The theory suggests that the gravitational pull of matter in the universe could eventually cause it to collapse in on itself, similar to a black hole.
