Have we finally detected dark energy? The implications could be enormous, Dr. Sunny Vagnozzi, lead author on a University of Cambridge paper on the subject, tell us over email. "Directly detecting dark energy, and in particular its non-gravitational interactions, would have a tremendous impact," he explains. 

In a paper published on Sept. 15 in the journal Physical Review D, Vagnozzi and a team of University of Cambridge researchers detail how unexplained results from an experiment called XENON1T may have been caused by dark energy rather than the dark matter the experiment was supposed to detect. The new paper constitutes a large step towards the first direct detection of dark energy, the researchers say.
