Unlocking the Cosmos: How Supermassive Black Holes Could Revolutionize Particle Physics at a Fraction of the Cost

A recent study from Johns Hopkins University reveals that supermassive black holes could be generating high-energy particle collisions, similar to those scientists aim to recreate on Earth.

Published in Physical Review Letters, this groundbreaking research suggests that spinning black holes might act as natural particle accelerators, potentially surpassing the Large Hadron Collider (LHC). This discovery is crucial as funding for fundamental physics is becoming harder to secure, and the dream of building more advanced colliders remains distant.

For around a decade, physicists have speculated that supermassive black holes could produce these energetic collisions. Andrew Mummery, a co-author and theoretical physicist at Oxford, sought to validate this idea by exploring how these black holes could inherently generate such phenomena. This understanding could open new avenues for studying dark matter and other elusive particles, which remain a mystery for scientists.

Joseph Silk, another co-author and astrophysicist also at Johns Hopkins, highlighted the challenge that current colliders face in finding dark matter. While the LHC has yet to provide evidence for dark matter particles—believed to compose about 85% of the universe’s mass—there’s an exciting possibility that nature itself might offer insights through these black holes.

At the LHC, protons are smashed together at nearly the speed of light to examine the universe’s fundamental components. Interestingly, studies indicate that supermassive black holes could already be generating these elusive particles on their own. Some of these black holes spin so quickly that they can eject jets of plasma at incredible speeds. Mummery and Silk’s research focused on the chaotic environments around these spinning giants, where gas flows can create particle collisions much like those within human-made colliders.

Silk mentioned that while many particles get pulled into the black hole, some are ejected with tremendous energy. These ultra-energetic particles could potentially be detected by Earth-based observatories like IceCube in Antarctica or the KM3NeT telescope in the Mediterranean, which both already monitor elusive particles called neutrinos. Recently, KM3NeT reported detecting the most energetic neutrino ever, indicating progress in understanding these mysterious particles.

Understanding how high-energy particles arise near supermassive black holes could pave the way for exploring dark matter in a more natural, economical way compared to traditional colliders. This research not only reshapes our view of the universe but might also lead to new discoveries that redefine our understanding of physics.
