In the simplest version of the theory, the strength of dark energy—the faint, repulsive force that’s everywhere in the universe, pushing it apart—is fixed for all eternity. But DESI’s first release, last year, gave some preliminary hints that dark energy was stronger in the early universe, and that its power then began to fade ever so slightly. On March 19, the team followed up with the larger set of data that Riess was awaiting. It was based on three years of observations, and the signal that it gave was stronger: Dark energy appeared to lose its kick several billion years ago.
Sounds fascinating, but I could really use an abstract, for starters.
