On Earth, particle physics experiments accelerate charged particles to high energies, up to TeV levels, allowing for significant data collection. However, cosmic phenomena such as black holes and supernovae create natural particle accelerators that achieve energies in the PeV range, far beyond human capability. Recent advancements in astronomy have led to insights into the origins of these high-energy cosmic rays, suggesting that our own galaxy may be the source. The study of cosmic rays has evolved from early balloon experiments to modern techniques, marking progress in understanding fundamental particles and forces in the universe.
Cosmic rays, often found at PeV scales, reach energies that significantly exceed the capabilities of human-made particle accelerators, posing questions about their origins.
Natural particle accelerators like black holes and supernovae surpass Earth's capabilities by producing cosmic rays at energies up to and beyond peta-electron volts.
