Mathematicians are challenging the idea that dark energy is responsible for the accelerating expansion of the universe. In a ...

Our best model of the cosmos has a glaring mathematical problem, but we may have found an answer.

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 ...

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 ...

Dark energy is one of the greatest mysteries in modern physics, comprising nearly 70% of the universe and causing its ...

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 ...

Why is the expansion of our Universe accelerating? Twenty-five years after its discovery, this phenomenon remains one of the greatest scientific mysteries. Solving it involves testing the fundamental ...

Dark energy, the mysterious force that's driving the accelerating expansion of the universe, may not actually exist, scientists say. Their research has brought into question one of the cornerstones of ...

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 ...

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 ...
