Q. Amaterasu, is the high-energy cosmic-ray event recently discovered by Scientists of which country?
Answer:
Japan
Notes: Japanese scientists have identified a high-energy cosmic-ray event called 'Amaterasu,' marking the second-highest-energy cosmic ray ever recorded. Amaterasu's energy level surpasses that of the Large Hadron Collider by approximately 40 million times. The detection of such ultra-high-energy cosmic rays (UHECRs) holds significance for advancing our understanding of cosmic phenomena and subatomic particles, potentially challenging current theories in high-energy particle physics. Notably, Amaterasu's distinctive feature is its apparent origin from an empty region of the universe, opening up possibilities for uncovering unknown astronomical phenomena. Studying these cosmic rays offers insights into the sources of cosmic rays and contributes to an enhanced understanding of high-energy physics beyond the Standard Model.
