The standard model of how the universe works involves the widely accepted theory that dark energy is a fundamental constant of nature that drives the accelerating expansion of the universe. But a new ...

DESI maps distant objects to study dark energy. The instrument is installed on the Nicholas U. Mayall 4-meter Telescope, shown here beneath star trails. (Credit: KPNO ...

Data from a huge dark energy experiment is starting to suggest our current model of the universe is wrong. Physicists aren't completely sure yet, but they think they'll need a new theory for what ...

Their report, not yet peer-reviewed, seems to confirm that the standard model was operating as expected in the early universe. One element in that model, the Hubble constant, describes how fast ...

In the years since then, scientists have remained in the dark about what’s causing the universe’s prolonged growth spurt (hence the name “dark energy”). To construct their standard model ...

The findings bring astronomers another step closer to unmasking the mysterious nature of dark energy, which may mean that the standard model of how the universe works could also require an update ...

This hints that our best theory of the universe's evolution, the standard model of cosmology, could be wrong. The newly released DESI data comes from its first three years of observations ...
