Unexplained Ultra-High-Energy Cosmic Ray Baffles Astronomers

Astrophysicists at the University of Utah and the Telescope Array have detected ultra-high-energy cosmic rays, including the newly discovered Amaterasu particle, which challenge current understanding of particle physics. These particles have energies beyond theoretical limits and their origin and propagation remain a mystery. The Telescope Array, an ongoing research project, aims to unravel the unknown cosmic phenomena behind these rare cosmic rays.
