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

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 is one of the greatest mysteries of the universe. This mysterious force is thought to be accelerating the expansion of the cosmos. But a new study challenges this long-held belief. A team ...

New strategies may soon allow scientists to test dark energy theories within our own solar system, linking cosmic-scale physics to local observation. Science advances through a cycle of proposing ...

The Big Bang theory has dominated our understanding of the universe’s origin for almost 100 years. It describes a moment when ...

The birth, growth and future of our universe are eternally fascinating. In the last decades, telescopes have been able to observe the skies with unprecedented precision and sensitivity. Our research ...

What is dark energy? Why does dark energy seem to be weakening? Is our universe part of a larger multiverse? What lies beyond the boundary of a black hole? The universe seems to be rotating, and if ...

Forget one Big Bang — try many. A bold new theory pokes holes in the popular origin story, suggesting the universe evolves through a series of lightning-fast bursts, rewriting what we know about ...

Even though we can explore the universe with great precision, there is still a lot we don't know, according to Ulf Danielsson ...

Stars are still forming in the blue centre of the Messier 78 stellar nursery, emerging from the orange clouds at the bottom. — © AFP Stars are still forming in the ...

Although some compelling evidence exists to support the idea that a repulsive force similar to dark energy exists, it has yet to be directly observed or measured. To circumvent this uncomfortable ...

Black holes are eaters of all things, even radiation. But what if their rapacious appetites had an unexpected side effect? A new study published in Physical Review Letters suggests that black holes ...
