A team of physicists is using quantum matrix models to finally connect quantum mechanics with a theory of gravity

JILA Physicists have tested Albert Einstein's general theory of relativity, or more precisely, the effect known as time dilation, at the smallest scale ever, demonstrating that two tiny atomic clocks separated by only a millimetre, or the width of a sharp pencil tip, tick at different rates.

Physicists have measured time dilation on the smallest scale ever using an atomic clock made of thousands of ultracold atoms formed into a stack of pancake-shaped blobs

Dude, what if everything around us was just... a hologram? The thing is, it could be - and a physicist from the University of Michigan uses it; if

The laws of physics demand that we cannot see through a black hole's event horizon; it is fundamentally impenetrable. Even light cannot escape it.

On May 21, 2019, a ripple in the fabric of spacetime swept over Earth at the speed of light. These pass through us all the time, but this one was strong enough to warp space noticeably, at least to the detectors used by the LIGO/Virgo collaboration. As the waves passed, they compressed and rarefied a set of lasers beams, causing their lengths to change by a tiny, tiny amount: About 1/1000th the size of a proton. But it was enough.

Dude, what if everything around us was just ... a hologram? The thing is, it could be—and a University of Michigan physicist is using quantum computing and machine learning to better understand the idea, called holographic duality. Holographic duality is a mathematical conjecture that connects

New research has shown that future gravitational wave detections from space will be capable of finding new fundamental fields and potentially shed new light on unexplained aspects of the Universe.Professor Thomas Sotiriou from the University of Notti

"It took less than an hour to make the atoms, a few hundred million years to make the stars and planets, but five billion years to make man!" -George Gamow Earlier today, a video (from last month) was released where one of the members of the US House of Representative -- a member who sits on the House Committee for Science, Space and Technology -- proudly proclaimed the following:
