Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

Light has always been the stage on which quantum mechanics performs its strangest tricks, and the double-slit experiment is ...

A radical theory that consistently unifies gravity and quantum mechanics while preserving Einstein's classical concept of spacetime has been announced in two papers published simultaneously by UCL ...

Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to ...

'No understanding of or interest in modern physics': Einstein (pictured) was criticised by Oppenheimer - Library of Congress/Corbis/VCG via Getty Images Viewers of Christopher Nolan’s Oscar-hoovering ...

A unified Theory Of Everything is the holy grail of physics, but gravity refuses to play ball. Now, a newly proposed theory attempts to unify Einstein’s theory of gravity with quantum mechanics – and ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

Since Einstein, physicists have found that certain entities can reach superluminal (that means "faster-than-light") speeds and still follow the cosmic rules laid down by special relativity.

The pioneer of quantum computing talks about how Albert Einstein would have reacted to his experiments, the hype around the ...

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of physics.

The image depicts an experiment in which heavy particles(illustrated as the moon), cause an interference pattern (a quantum effect), while also bendingspacetime. The ...
