The rapid acceleration of the universe’s expansion continues to challenge our understanding of fundamental physics. Why the universe is expanding faster and faster remains one of the most intriguing ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

Scientists propose a new gravity theory using Friedmann equations. Their model explains the universe’s accelerating expansion ...

Our best models of the cosmos don't add up — but that could change if the universe is actually made of a viscous 'fluid,' a ...

The universe’s expansion might not be accelerating but slowing down, a new study suggests. If confirmed, the finding would upend decades of established astronomical assumptions and rewrite our ...

The expansion of the universe was not accelerating but was rather slowing down and at a rate much faster than expected, a new study suggested.

Add Yahoo as a preferred source to see more of our stories on Google. A lonely telescope in the Arizona desert tracks millions of distant galaxies to determine the ultimate fate of the Universe ...

A former Harvard physics professor argues that established cosmological theory places Heaven beyond the observable universe, ...

The Dark Energy Survey mapped 669 million galaxies to help understand why the universe's expansion is accelerating rather than slowing down.

The Universe has long been cast as effectively immortal, coasting into a cold, dark eternity so distant that it might as well ...
