In the past, physicist Stephen Hawking has hosted a champagne party for time travelers with balloons and hors d’oeuvres.

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

Their work introduces a new concept called q-desics, short for quantum-corrected paths through space–time. These paths ...

The famous double-slit experiment brings into question the very nature of matter. Its cousin, the quantum eraser experiment, makes us question the very existence of time – and how much we can manipula ...

What if the flow of time isn’t as one-way as it seems? Researchers from the University of Surrey have uncovered evidence that in the strange world of quantum physics, time could theoretically run both ...

What does the passage of time look like for a truly quantum object? The world’s best clocks may soon be able to answer this question, testing how time can stretch and shift in the quantum realm and ...

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 ...

Scientists have, for the first time, experimentally proven that angular momentum is conserved even when a single photon splits into two, pushing quantum physics to its most fundamental limits. Using ...

A century ago, science went quantum. To celebrate, physicists are throwing a global, year-long party. In 1925, quantum mechanics, the scientific theory that describes the unintuitive rules of physics ...
