One of the prevailing mysteries of quantum mechanics, the vanguard of the physical sciences, is the phenomenon of "non-locality," i.e., the apparent causal interaction of tiny particles across vast distances of space. The event violates our understanding of causality grounded in Newtonian physics as well as Einstein's conception of a space-time continuum undergirding all of reality. One proposition that gets us out of this conundrum is multiple universes. This solution, however, doesn't explain a number of other observations we've made of the universe, including black holes. Perhaps our understanding of space and time needs reconsidering, but where does our knowledge of the universe stand after that?
