Letters from renowned physicist Albert Einstein have become hot properties for auction houses recently. Christie's has the latest batch, in which Einstein criticizes other scientists for their understanding of quantum physics, going so far as to say "God does not play dice with the universe" in one of them.
A shocking new study suggest that, at a quantum level at least, two different versions of reality exist. The new study comes from the idea brought to the forefront in Eugene Wigner's friend scenario, which states that two people could see the same photon, or light particle, and have different observations of the photon. Even though the observations, and the conclusions drawn from those observations, are different, they would both be correct.
