Einstein–Rosen bridges may reflect a two-directional structure of time that preserves information and hints at a pre–Big Bang universe.

During the survey, researchers identified a promising 8.19-millisecond pulsar (MSP) candidate located close to Sagittarius A*, the supermassive black hole at the center of our galaxy.

An astrophysicist explains what wormholes are and how these theoretical space-time tunnels have popped up in the solutions to a set of decadesold equations.

Interstellar, Christopher Nolan’s visually stunning sci-fi drama starring Matthew McConaughey, is now streaming free on Tubi.

Some sci-fi movies take the genre extra seriously, using accurate technologies to ground their depiction of the future.

Quasicrystals are orderly structures that never repeat. Scientists just showed they can exist in space and time.

A physicist challenges the idea of wormholes as space tunnels, proposing they act as time mirrors linking opposite temporal directions.

Scientists scanning the heart of the Milky Way have spotted a tantalizing signal: a possible ultra-fast pulsar spinning every 8.19 milliseconds near Sagittarius A*, the supermassive black hole at our ...

Physicists artificially slowed down time to reveal the bizarre Terrell-Penrose effect, a consequence of special relativity. This image from the experiment shows a sphere seemingly moving at 99.9 ...
