They call this good news. LOL!

Hunt For Dark Matter Gets Good News

In a recent study published in Physical Review Letters, an international team of researchers led by the Albert Einstein Center for Fundamental Physics (AEC) at the University of Bern in Switzerland have carried out a precision experiment in hopes of focusing the search for the existence of dark matter.

"What dark matter is actually made of is still completely unclear," explains Ivo Schulthess, who is a PhD student at the AEC, and lead author of the study.

For the study, the researchers examined what’s known as dark matter axionlike particles (ALPs), which they identify as one of the more “promising candidates” in the hunt for dark matter. They measured the rotational frequency of neutrons, which they hypothesized would result in certain signatures being left behind when measurements were taken.

"Thanks to many years of expertise, our team has succeeded in designing and building an extremely sensitive measurement apparatus -- the Beam EDM experiment," said Dr. Florian Piegsa, who is a Professor for Low Energy and Precision Physics at the AEC, and a co-author on the study. "The rotational frequency of the neutrons remained unchanged, which means that there is no evidence of axions in our measurement.”

"Although the existence of these particles remains mysterious, we have successfully excluded an important parameter space of dark matter.”

So the good news is that they didn't find it and the space for finding it is getting smaller and smaller. LOL!
