A novel theory suggests that the current expansion rate of the universe is not fixed, but was in fact quite different in the ...

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 ...

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. Subscribe to our newsletter for the latest ...

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 ...

For the three astrophysicists who won the Nobel Prize in physics today (Oct. 4), it was only a matter of when, not if, they would get the prize, their peers said. Their discovery that the universe's ...

The accelerating universe as a research area investigates the observed late-time acceleration of cosmic expansion and its implications for fundamental physics and cosmology. It encompasses precise ...

Alex Filippenko, a professor of astronomy at UC Berkeley and a member of the National Academy of Sciences and the American Academy of Arts and Sciences, will present “The Accelerating Universe and the ...

In 1998, scientists discovered that our universe expands with acceleration, and in order to explain this effect, the concept of dark matter was introduced. This is a special type of energy that fills ...
