On 9 July 1925, Heisenberg sent a paper titled ‘Quantum-theoretical re-interpretation of kinematic and mechanical relations’ to Max Born, whom he was assisting at that time, and Born sent the paper to ...

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.

Their tests spanned the entire life cycle of the collision: inspiral, merger, and ringdown. Remarkably, the constraints were ...

In theory, hundreds of circumbinary planets should have been detected by missions such as NASA’s Kepler and TESS space ...

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 ...

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.

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

Two researchers have found an explanation for why we find almost no exoplanets orbiting binary stars. According to them, ...

General relativity doesn’t just bend light, it can influence planetary orbits enough to wipe out entire systems.

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.
