The Dark Energy Spectroscopic Instrument (DESI) is studying dark energy and the accelerated expansion of the universe.

The findings suggest that dark energy is dynamic and changes over time, and that it used to be stronger in the early stages of the universe but is weaker now. That’s particularly odd because most ...
