After five years of observations, DESI has built its most detailed 3D map of the universe and added weight to the possibility that dark energy may not be constant over time.

Using data from the Dark Energy Spectroscopic Instrument, researchers have built the largest 3D map of the universe yet, giving scientists a more detailed way to trace cosmic structure and probe dark energy.

The idea that the universe could eventually collapse and be reborn in another big bang had fallen out of favor, but new discussion around DESI data has given the big bounce fresh visibility.

The Dark Energy Spectroscopic Instrument has finished the largest 3D map of the universe yet, giving cosmologists a powerful new dataset for probing dark energy and testing whether the standard picture of cosmic expansio

The Dark Energy Spectroscopic Instrument has finished a five-year survey that captured more than 47 million galaxies and quasars, producing the most detailed map of the universe so far.
