Is dark energy constant or evolving? Last month, astronomers revealed a remarkable finding suggesting that dark energy, believed to drive the universe’s accelerated expansion, could diminish over time. This revelation led physicists to reassess traditional cosmological models, though some experts caution that such conclusions may be premature.
Since its launch in 2021, Arizona’s Dark Energy Spectroscopy Instrument (DESI) has been systematically measuring distances across millions of galaxies.
