Physicists Propose Cheaper Alternative to Particle Colliders: Supermassive Black Holes

A new study from Johns Hopkins University suggests that supermassive black holes—those cosmic behemoths lurking at the centers of galaxies—might already be generating the kinds of high-energy particle collisions researchers have spent decades trying to recreate here on Earth. Published today in Physical Review Letters, the study proposes that certain spinning black holes could serve as natural particle accelerators, rivaling or even exceeding the capabilities of the Large Hadron Collider (LHC). That’s a big deal, especially as funding for fundamental physics research grows increasingly scarce in the United States, and plans for next-generation colliders stretch far into the future. For about a decade, experts have theorized that supermassive black holes could do this, co-author Andrew Mummery, a theoretical physicist at the University of Oxford, told Gizmodo. But his study attempted to validate this theory by looking for naturally-occurring scenarios that would give rise to a black h ... Read full article.
