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 ...

Our latest and best ever map of the early universe is five times more detailed than anything we have had before, but while it precisely backs up the leading model of the universe, it is also a ...

The clearest pictures yet of the newborn cosmos strengthen the prevailing model of the universe but deepen a mystery about its expansion rate. Measurements of this rate, known as the Hubble ...

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 ...

It is quite amazing." The new results confirm a simple model of the universe and have ruled out most competing alternatives, according to the research team. The work has yet to go through peer ...

The new model forgoes the need for either dark matter or dark energy as explanations for the universe's acceleration and how structures like galaxies are generated. The researcher's work builds on ...

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 ...

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 evolving cosmos Dark energy and dark matter are two of the universe's most puzzling components. Together they make up roughly 95% of the cosmos, but because they do not interact with light ...

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 ...

This analysis, combined with other astrophysical data, offers mounting evidence that the impact of dark energy may be weakening over time and that the standard model of how the universe works may ...

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 ...
