There is no measurement that can directly observe the wave function of a quantum mechanical system, but the wave function is still enormously useful as its (complex) square represents the probability ...

Even given a set of possible quantum states for our cosmos, it's impossible for us to determine which one of them is correct ...

(via Sabine Hossenfelder) Physicists think that our universe started out as just a lot of quantum fluctuations. That means, if you’re able to calculate wave-function of those quantum fluctuations, you ...

Nearly a century after the development of quantum theories, a consensus has yet to emerge about what these theories tells us about ourselves and our places in the universe. Ney develops a framework — ...
