Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space ...

Observing the flow of time at the quantum scale reveals a puzzling energy phenomenon: the energy required to simply read the time astronomically exceeds that consumed by the device's operation itself.

Input/output is the term for time before and after a particular physical moment or scenario, and in certain quantum scenarios, those ‘befores’ and ‘afters’ can be interchangeable. Researchers have ...

Physicists have coaxed particles of light into undergoing opposite transformations simultaneously, like a human turning into a werewolf as the werewolf turns into a human. In carefully engineered ...

In the world of quantum physics, the rules that govern reality behave in ways that challenge what we think we know. Particles can be in two places at once. Actions on one particle can instantly affect ...

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result ...
