       In a video from @fermilab they discuss the "true solution to the twin #paradox".https://tilvids.com/videos/watch/e838a1ce-4b2c-40f9-8583-8b2743ffe119I skipped #relativity to do organic chemistry instead (still think it was the right call) so I'm rather naive about this.However, I'm highly skeptical about the proposed "solution" to the twin "paradox" for several reasons, the main one being of course that the thought experiment is physically impossible (infinite acceleration and instantaneous information transfer).Any educated opinions?

       when I say "impossible", I mean that it does not correspond to the situation of the traveling twin, of course the situation and math themselves are perfectly fine, they just seem (to me) irrelevant to the problem considered.

       @tfardet I think this person is trying to make a point about it being the change between inertial reference frames, rather than anything magical about non-inertial reference frames. You can keep the acceleration the same, but change the distances “coasted”, and the twin age difference changes. However… not remaining in the same inertial reference frame is what acceleration *is*, so I'm not quite sure where the argument is. “It's not acceleration, it's [thing identical to acceleration]!”
