Where was gravity when the universe was hot and dense ?

Sometime after around 10^-43 seconds apparently is when it started having effects.

At this time, it was denser and heavier than any black hole. Why it didn't collapse back then?

I am going to preface this by saying I'm no scientist. I think it is because the expansion velocity is so high. It would be nice to get a definitive answer.

Also, how is space expanding in time when space is already intertwined with time. Is the block universe expanding in meta time ?
