Einstein’s lost theory said gravity changes speed of light and a new experiment claims it was right
Albert Einstein postulated in his 1905 theory of special relativity that the speed of light in a vacuum is constant. Ever ...

For a wide variety of emerging quantum technologies, such as secure quantum communications and quantum computing, quantum entanglement is a prerequisite. Scientists at the Max-Planck-Institute for the ...
From the movement of stars to light streaming through stained-glass windows, light has long fascinated scientists and other thinkers. An exhibition at the Getty in Los Angeles explores how an emerging ...
The universe has a speed limit, and it's the speed of light. Nothing can travel faster than light — not even our best spacecraft — according to the laws of physics. So, what is the speed of light?
For the first time, researchers have detected empty voids moving faster than the speed of light — and they blazed past that cosmic speed limit without breaking the laws of relativity. A recent study ...
A video recorded during a thunderstorm over Tibet shows towering red sprites flashing above the clouds. The rare ...
