How exactly would you retrieve this rather dense amount of information
from the past without going back to when it was still coherently

This may not help you. By MWI as I understand it your time travel
would branch the universe or some subset thereof so you could not
bring information back to the same branch you started from.

Even granting that we do not yet know the truly fundamental laws of
physics it is not certain that engineers will find a way to do all
things that are possible to the degree of actually making doing them

things that can be done are worth the expense needed to do them or are
seen as good or advantageous to do. But that is another subject in
