Princeton scientists say Einstein's theory applies beyond the solar system
— 20 Mar 2010 15:19 | AstronomyA team led by Princeton University scientists has tested Albert Einstein's theory of general relativity to see if it holds true at cosmic scales. And, after two years of analysing astronomical…
Foiling an attack on general relativity
— 15 Mar 2010 15:32 | AstronomyEinstein's General Theory of Relativity explains gravity in terms of the curvature of space by mass. Dating from the second decade of the 20th century, after more than 90 years it is…
Galaxy study validates general relativity on cosmic scale, existence of dark matter
— 15 Mar 2010 12:45 | AstronomyAn analysis of more than 70,000 galaxies by University of California, Berkeley, University of Zurich and Princeton University physicists demonstrates that the universe - at least up…
Is the Milky Way doomed to be destroyed by galactic bombardment? Unlikely
— 1 Sep 2009 13:25 | AstronomyAs scientists attempt to learn more about how galaxies evolve, an open question has been whether collisions with our dwarf galactic neighbours will one day tear apart the disk of the…
QUIET team to deploy new gravity-wave probe in June
— 16 May 2009 13:37 | PhysicsA tiny fraction of a second following the big bang, the universe allegedly experienced the most inflationary period it has ever known. During this inflationary era, space expanded faster…
The day the Universe froze
— 9 May 2009 14:50 | PhysicsImagine a time when the entire Universe froze. According to a new model for dark energy, that is essentially what happened about 11.5 billion years ago, when the Universe was a quarter…
Refined Hubble constant narrows possible explanations for dark energy
— 8 May 2009 05:19 | AstronomyWhatever dark energy is, explanations for it have less wiggle room following a Hubble Space Telescope observation that has refined the measurement of the universe's present expansion…
Study plunges standard theory of cosmology into crisis
— 5 May 2009 16:55 | AstronomyAs modern cosmologists rely more and more on the ominous 'dark matter' to explain otherwise inexplicable observations, much effort has gone into the detection of this mysterious substance…
Dark energy found stifling growth in Universe
— 17 Dec 2008 10:30 | AstronomyFor the first time, astronomers have clearly seen the effects of 'dark energy' on the most massive collapsed objects in the Universe using NASA's Chandra X-ray Observatory. By tracking…
Scientists detect cosmic 'dark flow' across billions of light years
— 5 Oct 2008 22:48 | AstronomyUsing data from NASA's Wilkinson Microwave Anisotropy Probe (WMAP), scientists have identified an unexpected motion in distant galaxy clusters. The cause, they suggest, is the gravitational…
