The ability of particles to coordinate their behavior across distances may seem to violate the speed-of-light constant, but is a signal really being sent between them? Or does Einstein still reign?
Scientific advancement is more than a series of experiments: it is often a debate among scientists with fundamentally different points of view. Niels Bohr knew this firsthand thanks to Einstein.
The positing of universes parallel to ours, to explain the behavior of quantum mechanics, may seem like the weirdest idea ever. But it might be just the second-weirdest idea ever.
