(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.

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 ...

Using the world’s most powerful X-ray laser, researchers have captured the hidden, never-ending vibrations of atoms inside molecules. This first-ever direct view of zero-point motion reveals that ...
