Imagine if we could collect the energy out of thin air. And I mean it quite literally. You know how you were taught that a vacuum is nothing but empty space? That isn’t exactly true, at least in the ...

Try as they might, scientists can’t truly rid a space or an object of its energy. But what “zero-point energy” really means is up for interpretation. Suppose you want to empty a box. Really, truly ...

(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.
