While they normally have a mass and an electric charge, Pines asserted that they can combine to form a composite particle that is massless, neutral, and does not interact with light. He called this particle a &#8220;demon.&#8221; Since then, it has been speculated to play an important role in the behaviors of a wide variety of metals. Unfortunately, the same properties that make it interesting have allowed it to elude detection since its prediction.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2023-08-demon-physicists-year-old-massless-neutral.html\" target=\"_blank\" rel=\"nofollow noopener\">Demon hunting: Physicists confirm 67-year-old prediction of massless, neutral composite particle<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In 1956, theoretical physicist David Pines predicted that electrons in a solid can do something strange.
