Quote from article... "Cosmic rays are not actually rays, like light. They are instead subatomic particles, thought to be mostly protons, on of the fundamental units of matter. The highest-energy versions of them race across the universe at more than 99.9 percent of light-speed, packing in their tiny bodies more punch than a golf ball hit by a pro, explained physicist Glennys Farrar of New York University."
Now I am confused. Cosmic rays are typically shown on the electromagnetic spectrum and compared in similar terms to Gamma Rays, X-rays, visible light, and other EM frequencies.
How did things jump from photon to proton? Where exactly is the transition? Why are they still characterized in the same way?
Thanks,
Glenn
