Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists from ...

BOULDER- Black holes, time travel and E= mc^2. They are all related to Albert Einstein's Theory of Relativity. How many of us, though, can actually explain any of it? This year, Einstein's theory ...

Einstein’s equations were written for chalkboards and paper, yet they now sit at the heart of some of the most visually spectacular simulations ever run on a supercomputer. By folding general ...

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 ...

While the ΛCDM model has been a cornerstone of cosmology, it is showing its limitations as researchers seek to explain observations beyond its scope. (CREDIT: ESO/L. Calçada/spaceengine.org) The ...

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 ...
