[ExI] Many Worlds wins another one

[Henry Rivera]

I always favored Penrose’s view on this. I’ll have to check this out. Thanks!

In his Idea the Quantum Wave Function really does physically collapse and timing of the collapse depends on a random element and on gravity and thus on the mass density of particles in superposition; the more massive the object the shorter the time before the wave collapses and Penrose said that was the reason our everyday macro world appears to follow classical physics to an excellent approximation. However in the September 7 2020 issue of the journal Nature Physics there is a report of an experiment done in a laboratory deep under the GranSasso Mountain in Italy that produced results that are NOT compatible with Penrose's theory.
