New quantum experiments may settle the century-old Einstein vs Bohr debate, revealing key insights into quantum behaviour.

The constancy of the speed of light is a pillar of modern physics, but questions persist about its absolute universality. Advanced theories, seeking to unify general relativity and quantum mechanics, ...

Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to Albert Einstein’s instincts about reality. By stripping classic thought ...

'Exceptionally precise' set-up mimics thought experiment devised by sceptical genius to disprove the then-emerging field For the first time, scientists in China have faithfully recreated a thought ...
