In theory if the black holes are attracting and consuming all mass in the universe then they would attract each other as well, so what would happen when two black holes come across each other?
Then lets say theoretically the largest black hole consumes all other black holes and then? This is definitely food for thought, thanks for sharing.
This kind of thing absolutely fascinates me simply because like you say 'food for though'. Thanks for the comment.
No problem enjoyed the read!
