In quantum physics, every object, such as an electron, is matched to a mathematical formula called the wave function. The wave function encodes all the details of an object’s quantum state, which means physicists can predict what an object might do in an experiment by combining its wave function with other equations.

But if we accept that the whole world is quantum – and many researchers do – then much larger objects ought to have wave functions, including the whole universe. This is a point of view that was previously argued by, for instance, physics luminaries like Stephen Hawking.
