However, from the standpiont of evolving beings, the 'big collapse' is sort of like a convenient coincidence permitting transit into higher or lower dimensions, a kind of 'doorway'. Otherwise, we have to say that we aren't really evolved after all, because we are actually incapable of determining whether the linear development continues, or that we have no capacity to transit to higher or lower dimensions.
The going theory is physics appears to be that there is no causal relation between meso phenomena like humans and macro phenomena like galaxies. But couldn't there be some form of 'correspondence theory' or 'synergasm' in which human evolution is an attempt to predict natural laws to its own advantage?
This kind of theory would predict that the universe tends to live about as long as humans are capable of evolving. Unpredictable result, but sort of interesting. Otherwise, because of the gap in numbers, the universe tends to be best perceived as eternal and infinite, or as a handicap on human progress.
But, why would there be a 'gatekeeper' like black holes? It is more likely that past a certain point we have some control over the number of dimensions that are manifest, or at least the number of dimensions we perceive.
At this next level I am describing, it is more likely that the universe only expands or collapses when it meets some sort of infinite requirement, or else through quantum flux of some type.
That's my two cents.
