Einstein’s theory of gravity could be shaken by a cold beam of atoms
Researchers at the Swiss institutes of ETH Zurich and Paul Scherrer Institute (PSI) in Villigen have produced an…
Researchers tested gravity across galaxy clusters separated by hundreds of millions of light-years and found it behaves almost exactly as Newton and Einstein predicted, strengthening the case for dark matter
Astronomers have discovered that stars in the outer portions of galaxies tend to move much faster than expected…
‘Cosmic Glitch’ could explain why gravity acts differently across the Universe
Einstein’s theory of gravity may behave slightly differently across distances of billions of light-years, with gravity appearing about…
