This May Be the Strangest Explanation Yet for the Mysterious Particle That Slammed Into Earth in 2023
In 2023, the KM3NeT neutrino detector picked up an impossibly powerful signal—tens of thousands of times more energetic than anything produced by humanity’s best particle accelerators. Some scientists are now arguing that, simply, the signal came from an ancient black hole made of cosmic strings, hiding inside a fifth dimension. So, actually, not very simple—but according to a recent paper published in Physical Review D, the rules of quantum gravity “inevitably” lead to five-dimensional primordial black holes, or super-dense, hypothetical black holes from the cosmic dawn.

In 2023, the KM3NeT neutrino detector picked up an impossibly powerful signal—tens of thousands of times more energetic than anything produced by humanity’s best particle accelerators. Since then, scientists have tried to pinpoint its source, dipping into some creative—and arguably wild—explanations.cnx.cmd.push(function(){cnx({"playerId":"92b7b46b-43ed-4e0e-b21b-2c999302d9d7","settings":{"advertising":{"macros":{"AD_UNIT":"/23178111854/od.gizmodo.com/article","CHILD_UNIT":"article","POST_ID":"2000821675","POST_TYPE":"post","CHANNEL":"science","SECTION":"space","SUBSECTION":"","CATEGORIES":"space","TAGS":"astrophysics,cosmology,neutrinos,string-theory","NOP":"0"},"timeBeforeFirstAd":0}}}).render("cnx-player-main")}); But a new theory may just take the cake for the weirdest.
