Unveiling the Mystery of Simultaneity

Click For Summary
The discussion centers on the concept of simultaneity in the context of relativistic motion, particularly involving a hypothetical train moving at light speed. Participants clarify that simultaneity is frame-dependent; events deemed simultaneous in one frame may not be so in another due to the finite speed of light. They explore how an observer on a fast-moving rocket perceives two simultaneous flashes of light, noting that the observer sees one flash before the other based on their motion relative to the light sources. The conversation emphasizes the importance of understanding synchronization and the implications of the Lorentz transformation in different frames of reference. Ultimately, the discussion highlights the complexities of simultaneity in relativity and the necessity of considering the observer's frame.

Would someone explain paw's question and Jesse's answer? My thirst for knowledge drives me on!:confused: :confused: :confused:

(Assuming that you're referring to post #28)

Paw wants to know whether synchronised clocks go out-of-synch for an observer in relative motion due to the time it takes for light to travel from the clocks, because they are placed at different distances to the observer.

The short answer is No. As for an explanation, I don't think I can do it better than JesseM. :smile:

And so Santural understood the question.
And so he understood the answer.
And so he was happy again.
