The second reason is simple: location, location, location! The millisecond pulsar appears to be near Sagittarius A*, the supermassive black hole at the center of our galaxy. Sagittarius A* weighs ...

Researchers from Columbia University and Breakthrough Listen, a scientific research program aimed at finding evidence of ...

Confirming a pulsar star would enable unprecedented tests of General Relativity. Such a discovery would revolutionize physics ...

Ripples in space-time from a pair of merging black holes have been recorded in unprecedented detail, enabling physicists to test predictions of general relativity ...

Albert Einstein reminds us through this quote that true intelligence lies in clarity, not complexity. If you can explain an ...

Newton or Einstein—who got gravity right? 🌌 Neil deGrasse Tyson breaks down how classical physics evolved into relativity, explaining the key differences between force and space-time curvature in a ...

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

When someone proclaims anything with absolute certainty, I cringe. And when a politician does it, I double over in laughter.

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.

Different measurements of the Hubble constant, the rate of space-time expansion, refuse to agree – meaning we may have to look beyond Einstein’s theories to explain the universe ...

Most physicists doubt that time exists. On this page 40 years ago, we published scientific ‘proof’ of time being illusory. We pointed out that none of the equations of physics, from Newton’s laws to ...

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 ...
