A simulated universe works better when dark energy changes over time

Dark energy is a mystery so daunting that it stretches and strains our most robust theories. The universe is expanding, driven by the unknown force that we've named Dark Energy. Dark Energy is also accelerating the rate of expansion. If scientists could figure out why, it would open up a whole new avenue of understanding.

Scientists Stunned As Dark Energy Shows Signs of Weakening

For decades, scientists believed dark energy—the mysterious force pushing the universe apart—was constant. But what if it’s fading? What if the cosmos isn’t destined for an eternal freeze but could one day collapse in a fiery “big crunch”?New research from the Dark Energy Spectroscopic Instrument (DESI) suggests that dark energy, which makes up 70% of the universe, may have peaked billions of years ago. Scientist say Mysterious cosmic force appe…

Sky survey boosts the case for dark energy’s downturn

It’s looking more and more as if dark energy, the mysterious factor that scientists say is behind the accelerating expansion of the universe, isn’t as constant as they once thought. The latest findings from the Dark Energy Spectroscopic Instrument, or DESI, don’t quite yet come up to the level of a confirmed discovery, but they’re leading scientists to rethink their views on the evolution of the universe — and how it might end. Readings from DES…

Dark energy is weakening and the universe could (eventually) collapse, study says - TPR: The Public's Radio

The Dark Energy Spectroscopic Instrument (DESI) is studying dark energy and the accelerated expansion of the universe.

The end of our universe could be very different from what we previously thought. New data on ‘dark energy’ points to an alternative scenario: the ‘big crunch’, or the collapse of the universe.
