Some habitable worlds orbiting dead stars could be kept alive for aeons thanks to a quirk of Einstein’s theory of 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 ...

The gravitational lensing that causes this rare phenomenon cannot be explained solely by looking at observable ...

One of the most basic assumptions of fundamental physics is that the different properties of mass -- weight, inertia and gravitation -- always remain the same in relation to each other. Although all ...

Research teams on both sides of the Atlantic have shown that precise modeling of the universe and its contents will change the detailed understanding of the evolution of the universe and the growth of ...

Astronomers detected in unprecedented detail a collision between two black holes. Their observations confirm predictions made ...

In 1963, Roy Kerr, a New Zealand-based mathematician proposed a set of equations that explain the properties of rotating black holes as per Einstein’s theory of general relativity. These equations are ...

For over a century, Einstein's general theory of relativity has been key to understanding gravity. But new research suggests this theory "glitches" in the farthest reaches of space. That doesn't mean ...

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 ...
