Einstein rings help scientists study dark matter and cosmic expansion. Euclid will find thousands more lenses to map the ...

and a force that repels gravity known as dark energy (70 percent). Scientists have not yet observed dark matter directly. It doesn't interact with baryonic matter and it's completely invisible to ...

Dark energy, one of the most mysterious concepts ... It may be mind-blowing to us human beings, but variations in gravitational forces change the way that time progresses in the universe.

One of the driving forces behind that evolution is also one of our age's biggest mysteries in physics: dark energy. Dark energy is the name astronomers have given to the unknown force that is ...

The growing distances between them hinted at forces far beyond what we can see—dark energy and dark matter. As these supernovae dimmed over time, the universe’s expansion became undeniable.

However, the new theory that is slowly emerging negates the very presence of dark energy. This controversial stance, if proven, could rewrite our understanding of the cosmos and the forces that ...

Across cosmic history, powerful forces have acted on matter, reshaping the universe into an increasingly complex web of structures. Now, new research led by Joshua Kim and Mathew Madhavacheril at ...

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion. When you ...

Previous work has begun pulling apart these dueling forces, but dark matter and dark energy remain shrouded in a blanket of questions—critically, what exactly are they? Enter the Vera C.
