Cosmology assumes the quantum at a cosmological scale, and it is where a collapse makes the less sense. Who would observe and be responsible for the collapse of the universal wave? Belinfante estimates that the Copenhagen-von Neuman formulation of QM requires an external god looking at the universe, like materialism requires a god selecting a unique computation, but that’s no more doing science. François Englert, who worked in quantum cosmology, was very annoyed by the collapse problem, and was relieved that it makes sense to just abandon the collapse idea. The collapse is usually not even defined in any intelligible sense, and it introduces a duality incompatible with Mechanism, but also with the scientific attitude, I would say. With mechanism, there is only one consciousness which differentiates into many 1p histories, and they interfere statistically, notably by allowing a 1p plural observable and sharable reality. Why to believe in any “world"? Bruno > > @philipthrift > > On Thursday, October 3, 2019 at 5:22:02 PM UTC-5, Jason wrote: > Energy isn't even conserved under conventional cosmological models.
