In a World First, Physicists Narrow Down The Possible Mass of Dark Matter – ScienceAlert

We may not know what dark matter is, but scientists now have a better idea of what to look for.
Based on quantum gravity, physicists have worked out new, much more stringent upper and lower mass limits of dark matter particles. And they have found that the mass range is way tighter than previously thought.
This means that the dark matter candidates that are either extremely light or heavy are unlikely to be the answer, based on our current understanding of the Universe.
“This is the first time that…
