Answer 1

Yes, they can grow indefinitely. There is no limit to their size. In fact, our universe could be inside one and not realize it. It’s difficult to tell.

Also, black holes have this peculiar trait where they grow exponentially as they aquire more mass. Earth turned into a black hole would be the size of a coin. The whole universe turned into a black hole would be roughly 14 billion light years across.
