Could there be a black hole in the middle of our universe?

The universe may be infinite in size, meaning that we can only see a small portion of it, or it may be the observable universe, which is made up of all the stars and galaxies that are visible to us and has a diameter of roughly 93 billion light years.

The question is: Where is the center of the universe? If it is infinite, then there is no such thing as a center. We could define the center of the universe using a concept like the center of mass of the observable universe.

A supermassive black hole is found at the center of most large galaxies; these black holes have an impact on galaxy evolution and may even be the source of galaxy formation.

Supermassive black holes are almost certain to be found in large galaxies that are close to the observable universe's center of mass.

Despite the lack of direct observational evidence at this time, it is possible that a supermassive black hole exists at the center of the universe.
