Could there be a cycle of big bangs to big crunches, with a critical mass for a black hole causing it to explode/bang? During crunch phase localized black holes would form and possibly consolidate, and then instead of big bang being the entire mass of the universe, it can be most of the mass in the universe?
I think OP is saying this is very old because there is no mass around it for it to "feed" anymore. It would seem more probable for it to predate big bang rather than form soon after it.
