A friend of mine and me came up with an interesting idea
Hypothetical speaking :
Suppose, that astronomers have it the wrong way around. Suppose that black holes do not happen from exploding stars with x sun masses. Suppose that black holes are really some left over phenomenon from big bang events. The reason why, is that every galaxy has a black hole. But not every black hole is actively eating away, some black holes do not consume matter while there is matter surrounding those black holes. Suppose a black holes is needed to create a galaxy by using it's tremendous gravity to push matter together to form solar systems. In the end, everything spirals towards the black hole. But what happens to a black hole when it has to much mass ?
Or is there no such thing as having to much mass for a black hole. Maybe a black hole is a rift in our universe.
I saw this documentary about black holes :
