Astronomers are rethinking one of cosmology’s biggest mysteries: dark energy. New findings show that evolving dark energy models, tied to ultra-light axion particles, may better fit the universe’s ...

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 ...

Scientists know dark energy makes up about 70% of the universe and is responsible for the universe's accelerating expansion. Beyond that, little about it is certain, so WVU engineer Kevin Bandura is ...

Researchers from the Centre for Theoretical Physics, Jamia Millia Islamia, in India have combined data from baryon acoustic oscillations and supernovae to question our understanding of the nature of ...

The vast majority of matter is dark – invisible until it is detected only through its gravitational effects. The newly discovered object could be a clump of dark matter, or it could also be a compact, ...

Scientists still don’t know what dark matter is. It doesn’t interact with any electromagnetic force or regular matter except through the gravitational force it exerts. A research team has a come up ...

A recent study by Rajendra Gupta, published in "Galaxies," proposes that cosmic phenomena conventionally ascribed to dark matter and dark energy can be explained by the temporal weakening of ...

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 ...

Dark energy, the invisible force making up 70% of the universe, accelerates cosmic expansion and could one day cause the “Big Rip” where everything is torn apart. House Democrat who confronted Johnson ...

Dark energy is responsible for the expansion of the Universe, but its true nature is still a subject of much debate. Computer simulations based on the latest astronomical data enable scientists to ...

For decades, astronomers have believed that dark matter and dark energy make up most of the universe. However, a new study suggests they might not exist at all. Instead, what we perceive as dark ...
