After a while, Terra, who considers that Galaxy flies away
from her at a velocity v, claims that Galaxy is now younger
than her, exactly like GRists claim that time goes slower on
SN because of space expansion.
According to Terence, both Terra and the GRists are wrong,
because Terra's clock and Galaxy's clock tick at the same
rate."

Till now, none of them dared to comment.
They should at least try to demonstrate that Terence is wrong.
As long as they play escapism, one has to conclude that
they are unsure of the validity of their paradigms.
In the meantime, further discussion is a mere waste of time.

In their individual frames of reference, their clocks all run at same
time. Upon their return, the travelers should both be slightly younger
than the sedentary triplet due to effect of motion on passage of time.
The travelers change are equal due to their equivalent motions.
