The discussion revolves around conceptual confusion regarding acceleration in the context of special relativity (SR), particularly as it relates to the twin paradox. Participants explore how acceleration affects perceptions of simultaneity and the passage of time between two observers in relative motion.
Participants do not reach a consensus on the nature of simultaneity and the effects of acceleration on observations. Multiple competing views are presented, and the discussion remains unresolved regarding the implications of acceleration on the perception of time and simultaneity.
Participants highlight limitations in their understanding, particularly regarding the assumptions about light travel time and the effects of acceleration on simultaneity. There is also mention of the need for clearer visual representations to aid in comprehension.
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.
