Is Our Model of Dark Energy WRONG? | New 4.2σ Results

https://www.youtube.com/watch?v=WNyY1ZYSzoU

Observations from the Dark Energy Spectroscopic Instrument (DESI) appear to indicate that dark energy isn't constant but decreasing in strength. The evidence for dark energy fading is just short of a formal detection, having observed a 4.2σ deviation from the standard lambda-CDM cosmological constant model. Cosmologists are now making efforts toward confirming the result.
