In this article adapted from his new book, "Waves in an Impossible Sea," physicist Matt Strassler explains that the origin of mass in the universe has a lot to do with music.

Since Newton had his initial revelation about gravity, our understanding of this fundamental concept has evolved in unexpected ways. In this week’s episode, theoretical physicist Claudia de Rham and co-host Janna Levin discuss the ways our current understanding of gravity needs to continue to evolve.

While devising a new quantum algorithm, four researchers accidentally established a hard limit on entanglement.

For decades, extremal black holes were considered mathematically impossible. A new proof reveals otherwise.

The largest-ever 3D map of the cosmos hints that the dark energy that’s fueling the universe’s expansion may be weakening. One community of theoretical physicists expected as much.

A long-awaited study of the cosmic expansion rate suggests that when it comes to the Hubble tension, cosmologists are still missing something.

Tensors are used all over math and science to reveal hidden geometric truths. What are they?

Carbon dioxide’s powerful heat-trapping effect has been traced to a quirk of its quantum structure. The finding may explain climate change better than any computer model.

Experiments that test physics and philosophy "as a single whole" may be our only route to surefire knowledge about the universe.
