If dark energy changes over time, ... “For people like me working on this for 25 years, we didn’t expect this to happen in our lifetime,” Ishak-Boushaki says. More data needed.

That just doesn't work. Just saying it’s consistent to the Lambda-CDM, ... and weak gravitational lensing studies—strong hints emerged that dark energy might be changing over time.

And once again, when combined with other datasets—from CMB, supernovae, and weak gravitational lensing studies—strong hints emerged that dark energy might be changing over time.

In particular, when DESI analyses the combination of its BAO results with the final DES SNeIa data, the significance of a ...

A new image taken by the Dark Energy Camera shows a "galactic onion," a shell galaxy with multiple layers that are spread out over a distance of 150,000 light-years.

“And so, the hope is that if we combine these separate measurements, we find more conclusive evidence for or against an evolution of dark energy over time.” Working toward discovery. So far, the ...
