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 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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

In studying the history of the universe itself, there is always a chance ... We would need to find an entirely new cosmological model, one that works as well as our current one but that also ...
