Physicists are eyeing charged gravitinos—ultra-heavy, stable particles from supergravity theory—as possible Dark Matter ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the ...

Recent advances in theoretical physics have increasingly highlighted the pivotal role of algebraic structures in unifying particle physics with quantum gravity. These approaches leverage sophisticated ...

It is shown, in an invariant manner, that the gravitational field of a fast-moving mass bears an increasing resemblance to a gravitational plane-wave field, the greater the speed of the mass.

Up until now, the prospect of anti-gravity technology has been strictly confined to science fiction stories and films alike. However, CERN physicists are set to begin an experiment that may well ...

The Wall Street mantra “greed is good” could soon be adopted by cosmologists to explain the origins of dark energy, the mysterious entity that is speeding up the expansion of the Universe. At a ...

Now that LIGO has detected their first gravitational wave signal, the part of Einstein's theory that predicts that the fabric of space itself should have ripples and waves in it has been confirmed.

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. The General Relativity picture of curved spacetime, where matter and ...
