The Dark Energy Survey Collaboration collected information on hundreds of millions of galaxies across the universe using the ...

Dark energy may be the most mysterious substance ever proposed, but many scientists are certain it exists. Why?

For forty years, the “Standard Model” assumed dark matter must be cold. If it moved too fast (which would have made it hot), ...

In an unprecedented step, researchers crafted a detailed model compatible with the universe’s accelerated expansion.

To explain these observations, they proposed a new kind of energy that is responsible for driving the universe’s accelerated expansion: dark energy. Astrophysicists now believe dark energy makes up ...

The rapid acceleration of the universe’s expansion continues to challenge our understanding of fundamental physics. Why the universe is expanding faster and faster remains one of the most intriguing ...

By studying ripples in space-time, physicists are testing wheather dark energy might stem from hidden dimensions, elusive ...

Researchers in Germany argue that a modified theory of gravity could explain universal expansion, removing dark energy from ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

For a generation, cosmologists have treated dark energy as a fixed backdrop, a steady pressure stretching space faster and ...

Distant, ancient galaxies are giving scientists more hints that a mysterious force called dark energy may not be what they thought.See an excerpt of an interview in the video aboveAstronomers know ...

Last year, we reported on an exciting hint of new physics in the first data analysis results from the Dark Energy Spectroscopic Instrument (DESI)—namely that the dark energy, rather than being ...
