Scientists are homing in on the nature of a mysterious force called dark energy, and nothing short of the fate of the universe hangs in the balance
Scientists are investigating dark energy, which makes up 70% of the universe, to determine if it's a constant force or weakening. Recent data from the Dark Energy Spectroscopic Instrument, mapping millions of galaxies, suggests dark energy may be waning, but more evidence is needed to confirm this. The implications for the universe's fate are still uncertain.
