Information on the study from Princeton is <a href=\"https:\/\/www.princeton.edu\/news\/2018\/01\/24\/chasing-dark-matter-oldest-stars-milky-way\">here<\/a>. This means that the distribution of velocities of the old stars should mimic the velocities of the unseeable dark matter. This then provides clues to what to expect from dark matter detectors, those giant subterranean tanks designed to pick up the atomic rebounds from dark matter particles colliding with them. Top quark Jim Cooney explains it all, while back home Charm quark Addie Dove tells us about another intriguing <a href=\"http:\/\/www.alienture.com\/this-meteorite-found-in-egypt-is-older-than-the-solar-system\/\">meteorite<\/a>, this one apparently from another solar system.
