New Analysis of Gravitational-Wave "Dark Sirens" Reveals Tension with General RelativityHONOLULU, Feb. 13, 2026 / PRZen ...

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

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

Time has an arrow: It only ever seems to move in one direction. The future is always unknown to us, while the past forever remains locked and inaccessible. And yet, the vast majority of the laws of ...

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

Planets orbiting dead stars known as white dwarfs might be able to remain habitable thanks to general relativity subtly altering their motion. When stars like our sun run out of fuel, they expand and ...

In 2019, the MAGIC telescopes detected the first Gamma Ray Burst at very high energies. This was the most intense gamma-radiation ever obtained from such a cosmic object. But the GRB data have more to ...

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 ...

The puzzle Einstein and Rosen were addressing was never about space travel, but about how quantum fields behave in curved spacetime. I ...

An international team led by Japanese researchers has made a 3D map of 3000 galaxies 13 billion light years from Earth, and found that Einstein’s general theory of relativity is still valid. Since it ...
