In quantum mechanics we have the Schrodinger’s cat thought experiment, a cat in a quantum superposition of being simultaneously alive and dead. And in relativity the twin paradox thought experiment, a space-faring twin ages less than her stay-at-home sibling. But what if we could combine these and send our quantum twin around the galaxy. Could we be simultaneously old and young? What would that tell us about the quantum nature of time? And would we need schrodinger birthday
