The experiment showed that Bohr was definitely correct when he argued for complementarity, and that Einstein had got it wrong. The more atom-rustling that was measured, the weaker the diffraction ...

A groundbreaking quantum experiment conducted by MIT physicists has turned a major page in the long-standing debate between ...

What is space-time? Depending on how fast you're moving or how close you are do Earth's gravity can change the way time feels ...

In a striking display of quantum physics, a team of researchers has recreated one of science’s most legendary ...

The mind-bending concept of time dilation results from a seemingly harmless assumption—that the speed of light is the same ...

Einstein's theory posits that mass distorts space. This distortion can bend light from distant objects. Astronomers use this ...

A prediction Albert Einstein's theory of general relativity made more than 100 years ago has been proven as scientists detect light from behind a black hole.

What exactly is gravity, and how does it work? From Newton’s early groundbreaking discoveries to Einstein’s revolutionary ...

A new proposed experiment testing Albert Einstein's idea on the speed of light could turn the Theory of Relativity on its head. Nathan Rousseau Smith (@fantasticmrnate) explains.

Just days after Albert Einstein's theory that nothing moves faster than light was called into question by a startling neutrino experiment, the long-dead physicist might have come to his own rescue.
