Once considered an oddity of quantum physics, time crystals could be a good building block for accurate clocks and sensors, ...

It’s unclear whether science as a discipline—and scientists as people—will ever be able to answer some questions definitively ...

Gravity used to be the most dependable rule in the cosmic rulebook, the quiet background force that never changed its mind. Now a series of discoveries and bold claims are turning that certainty into ...

Time may feel smooth and continuous, but at the quantum level it behaves very differently. Physicists have now found a way to measure how long ultrafast quantum events actually last, without relying ...
