This video looks at how physicists study time travel as a scientific concept, exploring what theories like relativity say ...

The discovery of the double pulsar stunned scientists 🌌 Professor Brian Cox explains how this rare cosmic system confirmed ...

Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth.

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational ...

Albert Einstein won the 1921 Nobel Prize in Physics, but not for relativity—the theory that made him famous. This article ...

A newly detected gravitational wave, GW250114, is giving scientists their clearest look yet at a black hole collision—and a powerful way to test Einstein’s theory of gravity. Its clarity allowed ...

The sharpest black hole collision ever detected just gave Einstein another win—and raised hopes that the next one might rewrite gravity.

One such mystery, described in a recent paper in The Astrophysical Journal Letters, concerns circumbinary exoplanets—or rather, the shortage thereof—in the now 6,000+ exoplanets confirmed to date.

At the Wits Digital Dome, Sjava reflects on 10 years of music by placing himself not above but among the stars that shaped ...

This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

Learn why only 14 out of over 6,000 exoplanets orbit two stars, and how Einstein’s general theory of relativity may be to blame.
