A hundred years ago, quantum mechanics was a radical theory that baffled even the brightest minds. Today, it's the backbone ...

(via Sabine Hossenfelder) Zero-point energy is one of the most intriguing phenomena of quantum mechanics. Because quantum particles are also waves, they must always have more than zero energy.

If you asked a thousand physicists, they would all disagree. This statement could apply to any number of topics – whether the universe is infinite, what dark matter is made of, how to make wires ...
