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

Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to ...

Physicists in China have brought one of Einstein’s thought experiments into reality—but not quite with the outcome he hoped ...

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

Einstein’s theory of general relativity has been challenged by a team of researchers having conducted a 16 year-long experiment. The theory, which Albert Einstein published in 1915, is the cornerstone ...

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

Quantum mechanics is weird. When you think you have reached the bottom of its weirdness, you always discover a new ...

Albert Einstein was well known for his thought experiments involving complex scientific ideas. Often he used real-world examples that helped non-scientists grasp his theories of relativity. He started ...

A single atom as a movable slit: Researchers realize Einstein's thought experiment in original form, observing ...

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

Decades in the making, a space probe that delves into Albert Einstein's general theory of gravitation remains grounded on Earth, caught in its own space-time continuum of technical snags, costly ...
