The discussion centers on the conceptual confusion surrounding simultaneity and acceleration in the context of the twin paradox and the Andromeda paradox. Participants clarify that Bob's perception of Alice's time changes rapidly due to the Doppler effect rather than time dilation. They emphasize that during Bob's acceleration, his frame of reference shifts, leading to a different interpretation of simultaneity. The conversation highlights the importance of understanding Lorentz transformations and the implications of changing inertial frames in relativistic physics.
PREREQUISITESStudents and enthusiasts of physics, particularly those interested in special relativity, time dilation, and the implications of acceleration on perception of time and simultaneity.
The links are specifically about it, as are many threads here already. Here the PDF of the Weeks article:sophiecentaur said:Perhaps you could translate those links instead and help with identifying and explaining the 'preferred frame'. Those links introduce so much other stuff that my paths is getting more divergent than the convergent I was hoping for.

Yes, Minkowsky diagrams with light cones. Since the light paths are invariant pick any two coordinate systems "moving" and "stationary" and compare "events"; where the cones intercept world lines. You get wave crests (that start at different times) or clock ticks or whatever (birthdays..).anorlunda said:It is really hard to textile questions like this with words. Draw diagrams.
