Space is filled with a variety of objects, some blisteringly hot, some tremendously cold, but areas with little to nothing at ...

Our best models of the cosmos don't add up — but that could change if the universe is actually made of a viscous 'fluid,' a ...

If ever spotted in the emptiness of space, according to theoretical physicist Eugeny Babichev of the University of ...

Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem ...

Flashes like Cherenkov radiation in space may reveal negative-energy ghosts, hinting at gaps in gravity theories.

Groundbreaking advances in solar and space physics have provided key insights into the inner workings of the heliosphere, the vast protective bubble formed by the solar wind that extends from the Sun ...

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. When you purchase through ...

"Precision in these measurements is critical, as even subtle discrepancies could signal deviations from the model — potentially revealing new physics." When you purchase through links on our site, we ...

For more than a century, physics has treated space and time as the smooth stage on which the universe unfolds, a flexible fabric that bends but never breaks. A new wave of theories is now challenging ...

Wormholes are often imagined as tunnels through space or time — shortcuts across the universe. But this image rests on a ...

Five years after the collapse of the Arecibo Observatory telescope — the world’s largest single-dish radio telescope until 2016, when China completed a larger one — space physicist Qihou Zhou is ...
