Presently we can effectively understand the Universe down to the Plank Time - 10-43 seconds. That's pretty small, but obviously within that time interval a large number of interactions between particles occurred. Before that time we need a better theory of quantum gravity to unify the four fundamental forces.
But it seems to me that at least at some point, it is pointless to continue. At some miniscule interval, no interactions in the universe occurred. What is that interval? I don't know whether it is 10-45 seconds, or whether it is 10-4500 seconds.
In the very early uniiverse, given the incredible densiities, I would suspect that the interval is a lot smaller than it is today. Time slows down in a large gravitational field, and of course particles were crammed in a lot closer than they are today.
I've never heard of any discussion of this topic in the professional or amateur literature, but perhaps someone out there knows.
TIA!
