The discussion revolves around the nature of cosmic rays, specifically whether they are primarily composed of protons or if neutrinos play a significant role. Participants reference a New York Times article that suggests cosmic rays could be neutrinos, prompting a debate on the definitions and terminology used in the context of cosmic rays.
Participants express differing views on the composition of cosmic rays, with some asserting they are primarily protons while others entertain the idea that neutrinos could be included in the discussion. The discussion remains unresolved regarding the definitions and implications of the term "cosmic rays."
There are limitations regarding the definitions of cosmic rays and the assumptions underlying the claims made by the New York Times article. The discussion highlights the potential ambiguity in terminology and the need for clarity in scientific communication.
Using a grid of light detectors similar to the Baikal telescope, IceCube identified a neutrino in 2017 that scientists said almost certainly came from a supermassive black hole. It was the first time that scientists had pinpointed a source of the rain of high-energy particles from space known as cosmic rays ...
