Physicists in Israel have created a quantum interferometer on an atom chip. This device can be used to explore the fundamentals of quantum theory by studying the interference pattern between two beams ...

Dark energy -- a mysterious force pushing the universe apart at an ever-increasing rate -- was discovered 26 years ago, and ever since, scientists have been searching for a new and exotic particle ...

Physicists are no longer content to simply listen to ripples in spacetime. A new proposal sketches out how an exquisitely tuned laser experiment could, in principle, nudge gravitational waves ...

Physicists seem to be obsessed with cats. James Clerk Maxwell, the father of electrodynamics, studied falling feline s to investigate how they turned as they fell. Many physics teachers have used a ...

When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of light and cause tiny distortions in space-time. Albert Einstein predicted ...
