Barbour’s universe/multiverse is much more complex than a classical timeful universe. And it isn’t especialy likely, either. Specualtion =/= proof. To say the least.
Could you expand on that? I had the impression that timeless physics was larger in RAM, but not on disk—where it counts for MML, Solomonoff Induction, etc.
I took it to mean that it requires you to keep track of more state at any given time, but that the whole system has less logical complexity when you write it all down. Sort of like the difference between estimating the future state of a restricted N-body problem with numerical methods vs. solving it directly.

I’m afraid I don’t understand your RAM/disk metaphor.

There are no “given times” in Barbour’s universe. And who’s the “you”? An internal or external observer?
