The effect is not due to time dilation (which is symmetric for two people
walking in opposite directions). It's due to clock desynchronization:
two clocks, at the front and rear of a moving rocket which at rest were
synchronized, when moving relative to you appear desychronized.
The effect is proportional to length. Which is why very low speeds are
needed for astronomical distances, like here to Andromeda. It's due to
Andromeda, and all space between, being rotated in spacetime.
Another way to look at it, is consider length contraction as an effect of
on object being rotated in spacetime. We see only the 3D "shadows" of what
are 4D objects. This shadow contracts just like the shadow of an umbrella
pointed at the sun contracts when titled. But the umbrella is still the
same size. Similarly the proper length of an object in spacetime doesn't
change, but now some of its length that used to reach through space now
reaches through time. So the two ends of an accelerated meterstick will
reach through time, and be at slightly different ages.
