Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space ...

The rapid acceleration of the universe’s expansion continues to challenge our understanding of fundamental physics. Why the ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in ...

Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

The breakthrough could suggest a way to study 'quantum gravity,' the missing link between quantum physics and Einstein's general relativity in the lab. When you purchase through links on our site, we ...

Teaching relativity to a dog may sound like a hopeless mental exercise, but physics professor Chad Orzel says it actually makes the job of teaching relativity to humans easier. "It makes the whole ...

Strangely, although we feel as if we sweep through time on the knife-edge between the fixed past and the open future, that edge—the present—appears nowhere in the existing laws of physics. In Albert ...
