Imagine if it were possible to pull energy straight out of empty space. Not from fuel, not from sunlight, but from nothing ...

(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.

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 ...

Most of us find it difficult to grasp the quantum world. According to Heisenberg's uncertainty principle, it's like observing a dance without being able to see simultaneously exactly where someone is ...
