According to QM, in small systems evolving according to the Hamiltonian, time certainly exists but there is no arrow of time within the scope of the experiment. In such small systems we can run the movie backwards and everything looks normal. Of course the movie can't include a measurement suitab

All this talk of quantum immortality seems like anthropocentric wishful thinking to me. You are a process. All physical objects are best understood as slow processes. A life process is a very complex physical pattern, which is an arrangement of matter and energy in space-time, that has propert

As I recall, Tegmark also said that there would be classically deterministic universes, with no quantum physics at all. So, it seems that an SAS in such a universe would have no reason to surmise a Level III multiverse. It makes you wonder what things we SASs don't know about, that might have le

I'm sure we all agree that QM on its own is not the full story. Ditto with GR. Has anyone claimed to come up with a self consistent, complete description of our universe? Saying that "all universes exist which follow the MWI" is putting too much faith in a partial (and perhaps merely approximat
