The sun is about 4.5 billion years old and will continue to burn hydrogen for about 5 billion more years. Then it'll begin to go to red giant stage, and eventually a white dwarf.
Our universe is 10-20 billion years old. The big bang happened somewhere between that time.
And I don't even think the milky way will collapse on itself. We just never really knew for sure what was at the center of a galaxy. Everyone assumed a black hole, cause it makes sense, but there was never any proof. Now I suppose this is a bit of proof.
