Discussion Overview

The discussion revolves around the characteristics of a fermion that purportedly moves at the speed of light, with a focus on neutrinos and theoretical frameworks such as Rishon Theory. The scope includes theoretical implications and potential homework-related inquiries.

Discussion Character

  • Debate/contested, Conceptual clarification, Theoretical exploration

Main Points Raised

  • One participant asserts that the fermion in question moves at the speed of light and identifies it as a fermion.
  • Another participant suggests that (anti-)neutrinos could be the fermion referenced.
  • A different participant challenges this by stating that recent data indicates neutrinos have mass and do not travel at the speed of light.
  • One participant speculates that the question might be based on outdated information, possibly intended as a homework question prior to current experimental findings.
  • A later contribution reiterates that a massless fermion, as proposed in Rishon Theory, could theoretically travel at the speed of light, contingent on the acceptance of that theory.

Areas of Agreement / Disagreement

Participants express differing views regarding the nature of neutrinos and their speed, with no consensus reached on the characteristics of the fermion in question or the validity of Rishon Theory.

Contextual Notes

The discussion highlights uncertainties regarding the mass of neutrinos and the implications of theoretical models like Rishon Theory, which may depend on specific interpretations and assumptions.

it moves with speed of light. it is a fermion.

(Anti-)neutrinos
 
But according to "newest" data, neutrinos have mass, and does not travel at speed of light.
 
I was assuming that it is a homework question, so it would probably have been set before the current experimental evidence.

I guess, if you are into Rishon Theory, you could say that the "v" Rishon is a massless fermion which would travel at the speed of light. If you think Rishon Theory is plausible, that is...
