Hi all,
This is a follow-up to post 140 on April 9, 2013, the Triplets20.jpg of Triplet's Paradox.
First of all, fantastic diagram.
Is the following logic right as can be gleaned off that excellent diagram of Triplets20.jpg right?
Both ships turn around (earth proper time 20 months) and approach each for a long time before either ship knows the other ship has turned around. In fact, it won’t be until Earth proper time 35 that each ship realizes the other has turned around. In fact, when they do realize the other ship has turned around, and did so awhile ago, the Doppler shift will go very fast from red to blue, hitting all the colors in between in sequence.
