The Universe is big, as Douglas Adams would say. The most distant light we can see is the cosmic microwave background (CMB), which has taken more than 13 billion years to reach us. This marks the edge ...

The large-scale structure of the universe—the gigantic, hierarchical cosmic web of structures bound by gravity—is mostly made up of dark matter. The growth of the large-scale structure, from ...

A group of researchers at the University of Waterloo and the University of British Columbia have discovered a potential "cosmic glitch" in the universe's gravity, explaining its strange behavior on a ...

Researchers have discovered a potential 'cosmic glitch' in the universe's gravity, explaining its strange behavior on a cosmic scale. A group of researchers at the University of Waterloo and the ...

Gravity has passed nearly every test physicists have thrown at it for a century. Yet on the largest scales in the universe, a small mismatch may be pointing toward a limit in Einstein’s theory. A team ...

Velocity streamlines within the reconstructed volume, with colored envelopes associated with the prominent nearby basins of attraction. The map and streamlines have been cropped to the region covered ...

This article predates the current owners of Science Blog. It has not been reviewed under the current editorial process and is kept as part of the archive. Velocity streamlines within the reconstructed ...

In 1965, British mathematician Roger Penrose proposed the cosmic censorship conjecture, a concept that suggests that singularities — regions where gravity is so strong that the fabric of spacetime ...

Cosmic inflation posits a brief epoch of accelerated expansion in the early Universe, resolving the horizon and flatness puzzles while laying down the primordial density fluctuations that seed cosmic ...

The Universe on the largest scales exhibits a complex network of filaments, sheets and voids that together form the cosmic web. This web is generated by the gravitational growth of primordial density ...

Add Yahoo as a preferred source to see more of our stories on Google. A cosmic glitch in gravity may make gravity about 1% weaker across billions of light-years, challenging Einstein's theory at vast ...
