Shattered glass does not leap back into your hand. Smoke from a match does not gather itself and crawl back inside. In ...

Time travel is deterministic and locally free, a paper says —resolving an age-old paradox. This follows research observing ...

Warp drives have long lived in the realm of science fiction, but the underlying physics that inspired them is very real and ...

Researchers demonstrate that by shaping the spatial and temporal structure of photons, they can engineer customized quantum ...

A new experiment using Google’s Sycamore quantum processor has taken a bold step toward testing ideas from quantum gravity. For the first time, researchers successfully sent quantum information ...

Using a quantum computer to simulate time travel, researchers have demonstrated that, in the quantum realm, there is no "butterfly effect." In the research, information—qubits, or quantum bits—'time ...

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 ...
