Is Dark Energy Getting Weaker? New Evidence Strengthens the Case.
Cosmologists have uncovered stronger evidence that dark energy -- the mysterious force accelerating cosmic expansion -- may be weakening over time. The Dark Energy Spectroscopic Instrument (DESI) collaboration presented their latest findings at the Global Physics Summit in Anaheim, California, reinf...
Cosmologists have uncovered stronger evidence that dark energy -- the mysterious force accelerating cosmic expansion -- may be weakening over time. Combined with supernova observations and cosmic microwave background data, their analysis shows a 4.2-sigma deviation from the standard Lambda-CDM cosmological model, which assumes dark energy remains constant. DESI will continue observing through 2026, eventually producing a final map expected to include 50 million galaxies, potentially providing definitive evidence for this cosmic paradigm shift.
