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 ...

A mysterious force called Dark Energy might be changing, in a way that challenges our current understanding of the nature of time and space.

The rapid acceleration of the universe’s expansion continues to challenge our understanding of fundamental physics. Why the ...

Physicists are increasingly entertaining a radical possibility: our familiar universe of three dimensions of space and one of ...

Astronomers have known for decades that the universe is expanding. When they use telescopes to observe faraway galaxies, they see that these galaxies are moving away from Earth. To astronomers, the ...

WASHINGTON (Reuters) - Scientists working in an international collaboration have tracked how the structure of the cosmos has grown over the past 11 billion years, providing the most precise test to ...

Two of the biggest physics breakthroughs during the last decade are the discovery that wispy subatomic particles called neutrinos actually have a small amount of mass and the detection that the ...

The universe's expansion may actually have started to slow rather than accelerating at an ever-increasing rate as previously thought, a new study suggests. "Remarkable" findings published today in ...

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...

Certain types of supernovae, or exploding stars, are more diverse than previously thought, a University of Arizona-led team of astronomers has discovered The results, reported in two papers published ...
