Discussion Overview
The discussion revolves around the measurement of the one-way speed of light using an experimental setup involving two clocks positioned 100 kilometers apart. Participants explore whether this setup can resolve the conundrum associated with measuring the one-way speed of light without relying on roundtrip measurements or synchronization conventions.
Discussion Character
- Debate/contested
- Experimental/applied
- Conceptual clarification
Main Points Raised
- One participant proposes an experimental setup where two clocks are synchronized using light pulses sent to them, questioning if this leads to a one-way speed of light conundrum.
- Another participant references previous discussions on similar topics, suggesting that the issue has been explored before.
- A participant argues that the synchronization of the clocks assumes isotropy of light speed, thus potentially biasing the conclusion about one-way speed measurements.
- One participant suggests that atomic clocks could be used to determine isotropy if they record the same elapsed time, but acknowledges the challenge of agreeing on the timing between the two locations.
- Another participant reiterates that any measurement of one-way speed requires a synchronization convention, which fundamentally influences the outcome.
Areas of Agreement / Disagreement
Participants express disagreement regarding the feasibility of measuring the one-way speed of light without a synchronization convention. Some assert that such a measurement is impossible, while others explore potential methods to address the issue.
Contextual Notes
The discussion highlights limitations related to the assumptions of isotropy and the dependence on synchronization conventions, which remain unresolved.
