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

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  
practical or the results of doing them sufficiently good.  Not all  
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  
this area.
