When i think about black holes and big bang i see a connection with one another. Imagine if black role is rly somekind of fabric between universes that will eventualy suck in our universe into a hairpin like mass  and when the process is done what happens is the explosion inside the blackhole that basicaly inflates it into a brand new universe that sits inside a blackhole aka space And that basically happens to infinity. Sorry i cant explain it better but thats how i always viewed it.
