A radical theory that consistently unifies gravity and quantum mechanics while preserving Einstein’s classical concept of spacetime is announced today in two papers published simultaneously by UCL physicists.
if everything is classical, a whole lot of stuff is going to be tough to explain like quantum superposition as it's used in modern qubits, or quantum tunneling experiments that have proven effective. Heck I'm even interested in the double slit experiment explanation in the context of these fluctuations from the paper
I've always thought the double slit experiment was easily explained by the fact that time as observed from the particles point of view doesn't pass. Therefore, to the particle, the order of events in the measurement are meaningless. So the measurement you took afterward happened before from the particles point of view.
While it's true that a photon doesn't see time pass, an electron does and they exhibit the same behavior in the double slit experiment. I don't see how the particles perception of time explains the results.
There is some current theories that time is a manifestation of entropy, and it isn't actually real. If that's true, then the idea would still hold. But, to be fair, if time doesn't exist, that still doesn't necessarily mean the double slit experiment is resolved.
