Dark energy/matter seems to be changing or evolving, rattling our view of universe

Like living in the Dark Ages again? 😊 I personally never liked these terms, i.e. Dark Energy or Dark Matter.

"If dark energy is in fact weakening, it would likely mean that science's understanding of how the universe works will need to be rewritten.

The new findings come from the Dark Energy Spectroscopic Instrument (DESI), which sits on a telescope at the Kitt Peak National Observatory in the U.S. state of Arizona. ..."

"The Dark Energy Spectroscopic Instrument used millions of galaxies and quasars to build the largest 3D map of our universe to date. Combining the DESI data with other experiments shows signs that the impact of dark energy may be weakening over time — and the standard model of how the universe works may need an update. 

Key Takeaways
  • The DESI collaboration published a new analysis of dark energy using their first three years of collected data, which spans nearly 15 million galaxies and quasars.
  • Researchers combined the DESI data with information from studies of the cosmic microwave background, supernovae, and weak gravitational lensing.
  • The standard model of cosmology struggles to explain all the observations when taken together — but a model where dark energy’s influence changes over time seems to fit the data well.

Dark energy seems to be changing, rattling our view of universe "Dark energy, the mysterious force thought to be driving the ever-faster expansion of the universe, appears to be changing over time, according to new observations released Wednesday."




DESI is a state-of-the-art instrument and can capture light from up to 5,000 celestial objects simultaneously. Mayall Telescope interior
