AG * > *Since the day it was discovered that a single photon or electron behaves as if it's a wave when it goes through 2 slits but behaves like a particle when it hits a photographic plate physicists have been saying that makes no sense, well maybe so, but that doesn't prevent it from being true because it most certainly is. The least silly story known that explains how that bizarre fact could possibly be true is Many Worlds, Objective Collapse is slightly sillier, and Copenhagen is much sillier, and Superdeterminism is an astronomical number to an astronomical power sillier. * > *> But obviously you are unable to understand my issue.* *I understand your issue but it's not your issue alone, for over a century physicists have had that exact same issue with experimental results performed in the quantum realm, they are all radically unintuitive; so any story used in an attempt to explain them is going to seem "silly".

The conservation of mass/energy is not a logical necessity the way that 2+2=4 is, instead that law was derived from experiments performed in a lab. In 1915 Einstein discovered General Relativity and it predicted the conservation law would not remain true over cosmological distances, and in 1929 Hubble discovered cosmological redshift and proved that Einstein was right. * * > If you claim it just disappears, then you're affirming magic.* > *Even in classical physics entropy is not conserved, do you think that fact is also magic? * > *> Relying on GR is a mistake IMO.
