A faint hydrogen signal from a 5-billion-year-old universe emerged after astronomers stripped away overwhelming radio ...

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 ...

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 ...

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 ...

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 ...

Scientists have been scratching their heads at the expansion of the universe since it was discovered nearly a century ago, particularly applying fundamental theories such as Einstein's Theory of ...

Decoding the 'Cosmic Dawn,' which occurred over 500 million years after the birth of the universe, through the arrangement of radio absorption lines—we have summarized a new paper on this research. In ...

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 ...
