Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

Supersonic experiments are forcing physicists to rewrite a rule of thumb that has guided metal design for roughly 70 years, and the implications reach far beyond the lab. By driving metals and novel ...

Researchers have discovered quantum oscillations inside an insulating material, overturning long-held assumptions. Their work at the National Magnetic Field Laboratory suggests that the effect ...

Could our universe be expanding then shrinking back into a tiny point, reliving a kind of big bang over and over again? Probably not, according to a mathematical analysis that argues that the laws of ...
