SUMMARY
The discussion centers around a proposed experiment using a taut clothesline and clothespins to demonstrate the speed of light. Participants clarify that the movement observed is not instantaneous but rather occurs at the speed of sound in the clothesline, which is significantly slower than the speed of light (c). The consensus is that the experiment does not involve light and fails to provide any valid conclusions about its speed. The thread concludes with a statement regarding the quality of the initial proposal and the need for clearer understanding.
