The cosmological constant is the mathematical description of the energy that drives the ever-accelerating expansion of the cosmos. It's also the source of one of the most enduring and confounding ...

A team of physicists has designed quantum algorithms that can model one of the most elusive behaviors in nature: a photon flipping its polarization inside an extreme electromagnetic field. The work, ...

(Viaframe/Stone/Getty Images) Although our Universe appears to be stable, it might just be in a temporary state of false calm ...

For the last 80 years, the theory of quantum electrodynamics (QED), which describes all electromagnetic interactions, has been a cornerstone of the standard model, withstanding the scrutiny of ...

Quantum mechanics — the breakthrough physics theory that paved the way to our modern understanding of atoms, molecules and light — is turning 100 years old next year. During that time, the theory has ...
