New supercomputer simulations hint that dark energy might be dynamic, not constant, subtly reshaping the Universe’s structure ...

The universe's expansion may actually have started to slow rather than accelerating at an ever-increasing rate as previously ...

“If confirmed, this would have profound implications for the fate of the universe,” said The Guardian. The study raises the ...

For decades, scientists have believed that the Universe is expanding at an ever-accelerating pace due to a mysterious force ...

By observing the brightness of distant dying stars, astronomers have long come to believe that the expansion of the universe ...

Evidence now suggests the universe’s expansion has started to slow, not speed up. The findings imply dark energy is weakening ...

A remarkable new study challenges the findings of Nobel Prize winning research into how our universe has changed over time.

Astronomers may have misread cosmic acceleration for 27 years. The universe may be slowing down, not speeding up.

For several decades, evidence has suggested that the expansion of the universe is accelerating. Crucial to those estimates ...

The popular consensus among scientists is that the universe will continue expanding until the bitter end. A team of ...

Astrophysicists at the University of Chicago have developed physics-based models suggesting that dark energy could be changing over time. Dark energy, the mysterious force causing the universe to ...

Dark energy—the term used to describe whatever is causing the universe to expand at an increasing rate—is one of the universe’s greatest mysteries. The most widely accepted theory currently suggests ...
