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 ...

For a generation, cosmologists have treated dark energy as a fixed backdrop, a steady pressure stretching space faster and faster forever. Now a wave of new measurements suggests that this invisible ...

After five years of mapping the sky in 3D — an area that stretches from Earth’s front porch to about 11 billion light-years away — researchers at the Dark Energy Spectroscopic Instrument (DESI) ...

Ask most astronomers, and they'll tell you that dark matter and dark energy make up more than 95 percent of the universe and that they are the explanations for many of the large-scale phenomena we ...

The universe’s expansion might not be accelerating but slowing down, a new study suggests. If confirmed, the finding would upend decades of established astronomical assumptions and rewrite our ...

For a quarter century, cosmology has leaned on one framework to explain how the universe expands. Known as the ΛCDM model, it assumes about 70 percent of the cosmos is filled with an unseen force ...
