Instead, scientists can only make inferences about it from its effects on the space and matter we can see. What’s new — In the paper, the researchers claim that hints of dark energy were detected at the Gran Sasso National Laboratory in Italy during an experiment designed to detect dark matter.
nec209 Posted April 17, 2022 Author Posted April 17, 2022 New type of dark energy may have been found. https://www.nature.com/articles/d41586-021-02531-5 Two separate studies — both posted on the arXiv preprint server in the past week1,2 — have detected a tentative first trace of this ‘early dark energy’ in data collected between 2013 and 2016 by the Atacama Cosmology Telescope (ACT) in Chile. If the findings are confirmed, they could help to solve a long-standing conundrum surrounding data about the early Universe, which seem to be incompatible with the rate of cosmic expansion measured today. But the data are preliminary and don’t show definitively whether this form of dark energy really existed.
