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

An artist's impression of the quantum experiment. (Courtesy: University of Southampton) The first technique capable of measuring the pull of gravity on a particle just microns in diameter could aid ...

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

Dark matter remains one of the biggest mysteries in fundamental physics. Many theoretical proposals (axions, WIMPs) and 40 ...

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 ...

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 ...

If you’re superstitious, a black cat in your path is bad luck, even if you keep your distance. Likewise, in quantum physics, particles can feel the influence of magnetic fields that they never come ...

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.

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.
