The renowned physicist Leonard Susskind has identified a possible quantum origin for the ever-growing volume of black holes.

For 50 years, the astrophysicist Martin Rees has contributed to our understanding of cosmology. Now he is speaking up about the promise and potential dangers of the science and technology that will arrive over the next 50 years and beyond.

The Frauchiger-Renner thought experiment has shaken up the world of quantum foundations.

Simple physical principles can be used to describe how rivers grow everywhere from Florida to Mars.

Quasars powered by supermassive black holes have been unexpectedly vanishing. Scientists have started to figure out why.

Experiments suggest that exotic superconducting materials share a “strange metal” state characterized by a quantum speed limit that somehow acts as a fundamental organizing principle.

In the latest campaign to reconcile Einstein’s theory of gravity with quantum mechanics, many physicists are studying how a higher dimensional space that includes gravity arises like a hologram from a lower dimensional particle theory.

A scientist and programmer with a literary bent, Valeria Pettorino thinks multiple angles and diverse points of view are needed to unriddle the nature of dark matter and dark energy.

Hot spots have been discovered orbiting just outside the supermassive black hole at the galaxy’s center. Their motions have given us the closest look at that violent environment.
