For decades, astronomers have puzzled over dark energy and why it's pushing our universe apart.; New data from the largest 3-D map of our universe suggests we may be wrong about dark energy. Dark ...

The 3D cosmic map building DESI has provided more clues that dark energy is weakening over time, suggesting our best model of cosmic evolution could be wrong.

Scientists using the Dark Energy Spectroscopic Instrument have unveiled the largest 3D map of the universe ever. The results suggest that dark energy, the mysterious force pulling the universe ...

The effects of dark energy on the universe may have changed over time, which could shake up how scientists view the universe, according to new research due to be presented at the April 4 meeting ...

The standard cosmological model known as Lambda-CDM (ΛCDM) proposes that dark energy is a constant force in the universe. However, an early “hint” in a new detailed map from the Dark Energy ...

Together, the data match dynamical dark energy better than the standard picture, by a statistical measure as large as 4.2 sigma, depending on which data are used, the researchers report in a paper ...

Using the Dark Energy Spectroscopic Instrument, or DESI, scientists have assembled the largest three-dimensional map of the universe to date. Earth is at the center in this animation.

Called the Dark Energy Spectroscopic Instrument (DESI), the collaboration released its first analysis of 6 million galaxies and quasars last year and has now added more data, bringing the count to ...

Physicists may need to come up with a new theory for how the universe works, after a dark energy experiment produced confounding results. An international team of scientists has released a "3D map ...

The 3D cosmic map building DESI has provided more clues that dark energy is weakening over time, suggesting our best model of cosmic evolution could be wrong.
