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 ...

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 ...

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’s theory of relativity has explained the universe for more than a century. But under certain conditions, cracks ...

Scientists could soon test Einstein's theory of general relativity by measuring the distortion of time. General relativity states that gravity is the result of mass warping the fabric of space and ...
