We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

Quantum theory has long treated time as a silent backdrop, a parameter that never jitters even as particles flicker in and ...

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 ...

The quantum world operates by different rules than the classical one we buzz around in, allowing the fantastical to the bizarrely normal. Physicists have described using quantum entanglement to ...
