Error014

I definitely agree with you that a thread sooner or later must come to an end

However I don agree with you that a solution has been reached at page 3

If you go through the thread the term "inertial system" is recursive

Sorry , it has nothing to do with the twin paradox

The twin paradox is an immediate and exclusive consequence of the special relativity

The relative speed only generate the permanent shift of time
You dont need anything else

The poblem of acceleration and deceleration is a false problem

I ask you a question :
Suppose that the duration of the journey at constant speed is very long,so long to make negligible the departure the arrival phases

Do you mean that the twins on arrival are equally aged ?

PS

if joey is not yet upset with me I would appreciate also his comment
