A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity to its toughest test yet.

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 ...

General relativity helps explain the lack of planets around tight binary stars by driving orbital resonances that eject or destroy close-in worlds. This process naturally creates a “desert” of ...

Astronomers may finally understand why planets orbiting two suns, the real-world equivalents of the "Star Wars" planet ...

New research suggests Einstein's general relativity explains the rarity of planets orbiting two suns. In tight binary systems ...

Casimir cavities are mysterious spaces between microscopic metal plates in a vacuum. Areas of diminished energy between the ...

Einstein was awarded the 1921 Nobel Prize for a theory that half of the people might not even have heard of. His Theory of Relativity, though world-changing, was not cited. Yet while delivering his ...

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

For the last 25 years, most scientists have believed that about 70% of the universe is formed by something called ‘’dark energy.’’ This invisible energy was ...

The second reason is simple: location, location, location! The millisecond pulsar appears to be near Sagittarius A*, the ...

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

Modern physics relies on "Dark Energy," "Dark Matter," and over 20 arbitrary tuning parameters to explain the universe. A comprehensive AI-driven audit performed by Gemini Pro on 20 technical papers ...
