Nora had read about multiverses and knew a bit about Gestalt psychology.

But almost everyone appears to agree on one thing. In some way or other, space-time itself seems to fall apart at a black hole, implying that space-time is not the root level of reality but an emergent structure from something deeper. Although Einstein conceived of gravity as the geometry of space-time, his theory also entails the dissolution of sp

In quantum mechanics, small deviations from a specified initial state tend to cause only small deviations from the predicted final state. Instead, accurate prediction is made difficult by quite a different effect.

A workable quantum theory of time – which would also be the quantum theory of gravity – has been a tantalizing and unattained goal of theoretical physics for some decades now.

But what physicists do so well, and most of us do so poorly, is that they carefully delimit what Newtonian and Einsteinian physics are able to explain. They know down to many decimal places where those maps are useful guides to reality, and where they aren’t. And when they hit uncharted territory, like quantum mechanics, they explore it carefully i
