Main Cosmic Ray
I added a Main page link to cosmic ray. Both Galactic Cosmic Ray and Extragalactic Cosmic Ray are just types of cosmic rays and the cosmic ray page is very well developed whereas the GCR and ECR are much shorter articles. If I'm very mistaken, I apologize and let's discuss here.174.49.84.214 (talk) 17:08, 10 February 2012 (UTC)

Modified energy range for ECRs
I modified the energy range for ECRs mentioned in the introduction (> 10^15 eV to 0.1-10 EeV, or about 10^19 eV). All references I can find support this, with the transition from galactic to extragalactic CRs being responsible for the ankle. The steepening of the spectrum at about 10^15 eV is because the containment of particles within the galaxy gets increasingly poor at this energy, at least per my understanding. If I'm mistaken about this let's discuss! Ramakr18 (talk) 15:37, 24 March 2021 (UTC)
