Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem ...

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

Thanks to Einstein’s relativity, time flows differently on Mars than on Earth. NIST scientists have now nailed down the ...

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

Since its introduction by Albert Einstein in 1905 (ref. 1), special relativity has been the accepted theory of local space-time. It not only resolved severe open questions in electrodynamics but ...

Einstein’s famous tenet of special relativity — that time slows down on a moving clock — has been verified 10 times more precisely than ever before. The result comes from physicists in Germany and ...

It's 2 a.m., and the noise from your upstairs neighbor is keeping you awake again. Take solace in the fact that by living above you he may be shortening his life, even if only by a tiny fraction of a ...

A new theoretical paper has tackled the phenomenon of quantum decoherence, the process by which objects slip out of the quantum world and start behaving classically. The paper approaches this in a new ...

The mass of Stein 2051 B, a white dwarf star located about 18 light-years from Earth, has been a subject of some controversy for over a century. Now, a group of astronomers has finally made a precise ...
