Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

Their work introduces a new concept called q-desics, short for quantum-corrected paths through space–time. These paths ...

For decades, quantum physics and general relativity have stood as two powerful but separate theories. Quantum physics explains the behavior of tiny particles like atoms and photons. General relativity ...

Theoretical breakthrough shows that time’s arrow can emerge naturally from how quantum parts become interconnected.

Quantum effects are no longer confined to ultra-cold chips and vacuum chambers. For the first time, researchers have ...

Using ultracold atoms and laser light, researchers recreated the behavior of a Josephson junction—an essential component of ...

By inserting tiny imperfections into the stones, scientists open up possibilities in computing, encryption and sensors ...

Every year, Santa Claus races around the globe in a matter of hours to bring presents to children all over the world.

Using the world’s most powerful X-ray laser, scientists have filmed atoms performing an eternal quantum dance that never stops — even at absolute zero.
