New research using a space-time phenomenon predicted by Einstein presents evidence that the invisible backbone of the ...

Scientists hope to probe the nature of general relativity through a possible pulsar found in the center of the Milky Way, ...

According to general relativity, gravity is the distortion of spacetime. Heavyweight cosmic entities like stars or galaxies ...

So cosmologists feel confident in modelling the universe using the “maximally symmetric” description of space-time in Einstein’s theory of general relativity. This symmetric vision for the universe, ...

On July 2, 2025, the China-led Einstein Probe (EP) space telescope detected an exceptionally bright X-ray source whose ...

It’s unclear whether science as a discipline—and scientists as people—will ever be able to answer some questions definitively ...

You might think galaxies can’t ever find each other in our runaway cosmos, but it turns out gravity can sometimes overcome ...

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

The team examined the remnant black hole’s “Kerr nature”, the mathematical description of a rotating black hole in general relativity. By analyzing the dominant quadrupolar mode and its overtone, they ...

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 ...

From the fall of an apple to the glow of the farthest known star, gravity quietly choreographs almost everything that happens in the cosmos. It shapes planets and people, bends light into celestial ...

Scientists pushed photons across the universe to test the speed of light—and found Einstein’s cosmic speed limit still holds ...
