For instance, in the Many Worlds theory it holds when we refer to all worlds together - ie we refer to the actual multiverse. Individual observers following experiences in one particular world (universe) do not experience conservation of angular momentum. MWT says all observers in all worlds do exist as one object in the Multuverse. At that level, the multiverse of many branching worlds seen as one undivided thing is local, deterministic, and satisfies all the conservation laws which physicists hold dear.
I think that Many Worlds Theory is just Many Words Religion. Opium for the masses. (The masses of busy research physicists who have no time or inclination to think).
Hi Richard. Agreed with that last point especially. The notion that every interaction leaving some permanent record (how permanent and defined exactly how?) creates a worlds-dividing spherical split wave moving out at light speed is too much for me to swallow. It's obviously a recipe for exponential explosive multiplication. Beginning presumably at time zero i.e. BB.
Has anyone worked out a 'reasonable' density of splitting worlds and rate of acceleration of the same, here some 13.8 by down the track? Seems to me it would likely have long ago reached a saturation value 'crisis'. Or is there no limit at all to information storage density that outlook seems to require? I would have thought Planck units place a natural cap of sorts.
Well anyway I get that what you are saying is that formally MWT can 'handle' my objection re locality and correlations. Guess I should have specified initially that MWI and e.g. backwards causation is not to be taken as viable answers here. But that's just my ignorant prejudices showing.
