THE HAPPENING WORLD: Has the XENON1T Experiment Detected Dark Energy?

A SCANALYZER post on 2021-09-10 discussed the XENON1T experiment and its detection of the decay of Xenon-124 with a half life of 1.8×1022 years, the rarest physical phenomenon ever directly observed. Now, a paper in Physical Review D (full text [PDF]) examines whether the excess electron recoils observed by XENON1T could be due to “chameleon-screened dark energy” quanta produced in the Sun.

Wouldn't it be ironic if a massive detector built to observe dark matter particles ended up detecting dark energy?
