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

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

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 ...

Einstein was awarded the 1921 Nobel Prize for a theory that half of the people might not even have heard of. His Theory of ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. An illustration of a planet orbiting a white dwarf star. New research hints that planets like ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...

When students learn that Albert Einstein won a Nobel Prize, the assumption feels automatic: relativity. The bending of space and time. The theory that redefined gravity and reshaped modern physics.

Researchers believe they have found the signal of a pulsar, the ancient core of a rapidly spinning star, at the center of the ...

As new and powerful telescopes gather fresh data about the universe, they reveal the limits of older theories like Einstein's relativity. When you purchase through links on our site, we may earn an ...

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 ...
