As Niels Bohr said, "Anyone who is not shocked by quantum theory has not understood it". Nonetheless, it looks like we are slowly getting closer to understanding whether the wave function of quantum physics --- the probabilistic function behind Schrödinger's half-alive-half-dead cat --- represents reality, or just our observation of reality.

This may seem like nitpicking, but it's an important distinction: is it how the Universe works, or a limit of how we measure the Universe? The answer seems to be the former. The philosophy of it is fascinating, if not a little sad that it requires so much domain-specific knowledge to fully comprehend.
