Hi Saibal, Hi Bruno, Patric has already explained Barbour's position (I didn't read his book). Separating space from time is not very natural... I agree. If only because of special relativity. But the very notion of space is quite complex. It is a reason why I find loop gravity more

I continue to describe a different way of talking than that used by Stathis, who writes [Saibal writes] The same is true here. It must follow from the laws of physics (which include the effects of simulations) that there are indeed many more copies of you at t2. Yes, we can say that

I'm not convinced that the QM no-cloning theorem applies to consciousness. We have no evidence one way or another that cloning is possible. So it is reasonable to take it as a working assumption, and work out the consequences (which is largely what Bruno has done), or conversely take the opposite
