The "Greatest cosmic energy" refers to the highest energy levels of cosmic rays that have been detected by the Veritas telescope array.
Veritas uses a system of four telescopes to detect the Cherenkov radiation produced when high-energy cosmic rays interact with the Earth's atmosphere. This allows Veritas to measure the direction and energy of the cosmic rays.
Detecting the "Greatest cosmic energy" allows scientists to better understand the origins and properties of these high-energy cosmic rays. It also provides insights into the extreme conditions and processes that exist in our universe.
No, Veritas can only detect cosmic rays with very high energy levels. Lower energy cosmic rays are not able to produce enough Cherenkov radiation to be detected by the Veritas telescopes.
The detection of the "Greatest cosmic energy" by Veritas can help scientists study the cosmic ray spectrum and better understand the sources and mechanisms of these high-energy particles. It may also have applications in the fields of astrophysics, particle physics, and cosmology.
