Does the universe notice that we're paying attention to a quantum experiment? The answer goes against everything we thought we knew.

A team of Chinese scientists has recreated a famous thought experiment proposed by Albert Einstein nearly 100 years ago, confirming a key principle of quantum mechanics. Their experiment shows that a ...

This sort of thing, called time dilation, may seem like the province of science fiction or esoteric physics, but this effect has surprising everyday implications. For example, when the first GPS ...

A thought experiment that was at the heart of an argument between famed physicists Albert Einstein and Niels Bohr in 1927 has finally been made real. Its findings elucidate one of the core mysteries ...
