If this theory is correct, we may live in a web of alternate timelines: "Quantum physics has royally messed up classical — and seemingly intuitive — principles of space and time, causality, and the conservation of energy. This means that Newtonian, and even Einsteinian, interpretations of the universe are insufficient. Indeed, if we’re to develop a unified and comprehensible theory of everything, we’re going to have to reconcile all of this somehow."
