Finding a theory of everything – explaining all the forces and particles in the universe – is arguably the holy grail of physics. While each of its main theories works extraordinarily well, they clash ...

Noether discovered that for every continuous symmetry of a system, there is a conserved quantity—that is, a quantity that ...

The question of how gravity interacts with the quantum world has long perplexed physicists, but a non-quantum theory of space ...

You may think of physics as a way to explain the behaviors of things like black holes, colliding particles, falling apples, and quantum computers. But a small group physicists today is working on a ...

Over the short span of just 300 years, since the invention of modern physics, we have gained a deeper understanding of how our universe works on both small and large scales. Yet, physics is still very ...

Why can't you take a lot of physics terms literally? Shouldn't “the Theory of Everything” be called “the theory of some things but not everything”? originally appeared on Quora: the place to gain and ...

Physicists in China have observed five phases in localization physics within a single quantum system. Using an advanced ...

Note: For a definition of unfamiliar terms, see our glossary. The fundamental particles of the universe that physicists have identified—electrons, neutrinos, quarks, and so on—are the "letters" of all ...

Between the summer of 1665 and the spring of 1667, Isaac Newton developed his theories on calculus, optics, and the laws of motion and gravity. He was quarantining during the Bubonic Plague and found ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. This article is more than 8 years old. A day or two ago, Sabine ...

Paul Dirac famously said “A physical theory must possess mathematical beauty”. This morning Radio 4’s Today programme asked Dirac’s biographer Graham Farmelo “How can a theory of physics possess ...
