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 ...

On January 22, 2025, physicists unveiled a groundbreaking discovery that could revolutionize our understanding of the universe and potentially unlock the secrets of time travel. The existence of ...

Physicists have found a way to measure how long ultra-fast quantum events actually take—without using a clock at all.

Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that describe gravity, quantum fields and the structure of spacetime now allow ...

EPFL physicists have found a way to measure the time involved in quantum events and found it depends on the symmetry of the material. "The concept of time has troubled philosophers and physicists for ...
