Scientists pushed photons across the universe to test the speed of light—and found Einstein’s cosmic speed limit still holds ...

Add Yahoo as a preferred source to see more of our stories on Google. A illustration shows a quantum experiment investigating gravity on a tiny scale. Scientists have determined a way to measure ...

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at ...

Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...

Physicists have directly mapped a hidden kind of geometry inside quantum materials that steers electrons in ways strikingly ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

Artistic representation of the implemented photonic experiment in which entanglement between the polarizations of single photons is mediated by the independent degree of freedom of the photon path.

Gravity has become an unlikely viral villain, blamed for an imagined global blackout in which the planet briefly lets go of ...

A new experiment will test the notion that gravity, one of the fundamental forces in the physical world, relies upon quantum physics to work. If so, it would further indicate the centrality of quantum ...

Detecting a graviton — the hypothetical particle thought to carry the force of gravity — is the ultimate physics experiment. Conventional wisdom, however, says it can’t be done. According to one ...

Virgin Galactic’s Purdue 1 suborbital flight in 2027 will probe the possibilities of in-space manufacturing and quantum technologies with autonomous experiments on board the all-Boilermaker flight.
