Discussion Overview
The discussion centers around the concept of whether the mass of a photon can be considered stationary in space, exploring implications for energy-mass equivalency and related theories. Participants reference various ideas and theories, including general relativity and the nature of photons.
Discussion Character
- Debate/contested
- Conceptual clarification
- Technical explanation
Main Points Raised
- One participant suggests that the mass of a photon could be viewed as a photon moving at light speed but stationary in space, relating this to energy-mass equivalency.
- Another participant challenges this idea, stating it appears nonsensical and emphasizes that photons cannot be stationary in space.
- A different participant points out the relationship between energy, mass, and momentum, stating that for a photon, the mass is zero, leading to the equation E = pc.
- Some participants reference a historical concept called a Geon, proposed by Wheeler, which involves light traveling in a circle held together by its own gravitational field energy.
Areas of Agreement / Disagreement
Participants express disagreement regarding the notion of photons being stationary in space, with some firmly rejecting the idea while others explore related theoretical concepts. The discussion remains unresolved with competing views on the nature of photons and mass.
Contextual Notes
Participants note limitations in discussing the topic due to the lack of specific references to the original article mentioned. There are also unresolved assumptions regarding the definitions of mass and energy in the context of photons.
