Dark energy: mysterious cosmic force appears to be weakening, say scientists

A recent survey from the dark energy spectroscopic instrument (Desi) team reveals that dark energy, the force driving the universe's expansion, seems to be weakening. This breakthrough could revolutionize our understanding of the cosmos by suggesting that the universe's expansion might reverse, leading to a 'big crunch.' The findings propose that dark energy peaked billions of years ago, prompting a significant shift in theoretical models. The implications of this discovery, discussed at the American Physical Society's summit, could shift the narrative from a 'big freeze' to an uncertain future for the universe.

The results suggest that dark energy is weakening, which could lead to a reversal of the universe's expansion and alter our understanding of cosmic fate.

Desi's findings indicate that dark energy may have peaked billions of years ago, potentially changing long-held theories on the evolution of the universe.
