- time dilation with a one way twin
(I swore to myself I would never ask a relativity question again...oh well)
I don't know why I can't find anything about this in a search so I guess I'll just have to ask. Is a twin that takes off to Mars to stay, younger than a stay at home twin or is it ambiguous? I would think that this could be determined simply by sending the current time to each other and subtracting the data travel time using distance and c, determining in this way if the Martian's clock had slowed. In reading some twin paradox threads it seems this can be ambiguous and is not determinable and that times cannot be compared unless the clocks are in the same location. I'm assuming for the sake of this question the relative velocity between Earth and Mars is 0 and am ignoring any gravitational effects.
