US EditionDark energy may not be constant—this discovery could undermine our entire model of cosmological history
- Berkeley Lab presented findings on dark energy in March at a physics summit.
- Dark energy, linked to the universe's accelerating expansion, has puzzled scientists.
- DESI used data from 14 million galaxies to map the universe's expansion over 12 billion years.
- Claire Poppett stated, "We expected to get a better measure of that accelerated expansion, and it's not at all what we found."
- The data suggests dark energy is changing, causing the universe's expansion to slow down.

Dark energy may not be constant—this discovery could undermine our entire model of cosmological history
The great Russian physicist and Nobel laureate Lev Landau once remarked that "cosmologists are often in error, but never in doubt." In studying the history of the universe itself, there is always a chance that we have got it all wrong, but we never let this stand in the way of our inquiries.

Einstein called it his “biggest blunder.” Now a Berkeley Lab breakthrough is shedding light on the mysteries of dark energy and cosmic expansion
Lawrence Berkeley National Laboratory has released new breakthrough findings on one of science’s biggest mysteries — one that Albert Einstein once called his “biggest blunder.” In March, Berkeley Lab researchers presented data gathered from 14 million galaxies at the American Physical Society’s Global Physics Summit in Anaheim, which has ignited new theories on dark energy – once thought to be a universal constant like gravity – as an evolving f…
