Physics

A mysterious object that repeatedly bursts with ultra-powerful radio waves must live in an extreme environment — something like the one around a supermassive black hole.

For decades, physicists have struggled to create a quantum theory of gravity. Now an approach that dates to the 1970s is attracting newfound attention.

What does measuring distances in sailing and astrophysics have to with motion sickness?

A complete classification could lead to a wealth of new materials and technologies. But some exotic phases continue to resist understanding.

This holiday season, catch up on science and math news while solving our year-end crossword.

Two mathematicians prove that under certain extreme conditions, the Navier-Stokes equations output nonsense.

The mother of all string theories passes a litmus test that, so far, no other candidate theory of quantum gravity has been able to match.

Updated results from a Japanese neutrino experiment continue to reveal an inconsistency in the way that matter and antimatter behave.

A famously difficult mathematical problem resisted solution for over 40 years. Mathematicians have finally resolved it by following an intuition that links number theory to physics.
