Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. When it comes to a science like physics, theoretical expectations must ...

A photon emitted from a star a billion light-years away arrives at a telescope having experienced no time whatsoever. Not ...

An artist's concept of twisted space-time around Earth. Albert Einstein's theory of general relativity is a monumental achievement of human ingenuity, creativity and perseverance — to say the least.

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 ...

DURHAM, N.C. -– Addressing a controversy first raised around 1910, two physicists have performed experiments with the aid of an engineer that validate anew the special theory of relativity's ...

Researchers at Osaka University demonstrate the relativistic contraction of an electric field produced by fast-moving charged particles, as predicted by Einstein’s theory, which can help improve ...

One hundred years ago today, in the wake of the first World War, a British astronomer watched a solar eclipse for signs that a German physicist may have been right about warps in the universe. The ...

Gravitational physics has become a truly experimental science as tests of the special and general theories of relativity reach new levels of precision Right on time When I was a first-term graduate ...

Have you ever imagined the solution to a logic problem instead of calculating it? Such “thought experiments” are carried out using one’s imagination rather than doing actual research. Typically ...

Achim Peters of the University of Konstanz in Germany and colleagues have used a super-stable laser standing wave to check Einstein's special theory of relativity three times more accurately than ...
