Follow?





Who cares if one or both accelerated in the past, as long as they are





*currently* travelling at constant velocity relative to one another?



I care. You can't understand it otherwise.
Though you may claim to.
Which one is moving through space toward or away from the other?
Only one is. The other only has a relative motion.
Like a ship from mars traveling to earth. The earth isn't
traveling through space toward the ship.

Einstein was wrong. He took relativity to far.
Moving through space is absolute. And if its not it is
because space can expand inbetween objects. That is
how the universe was created. Matter was flung out by
space motion.
Got it?

Why did you ignore the second part of my post?

In any case, are you really arguing that the one that accelerated in
the past is automatically the one that is "really" moving? Suppose two
ships are travelling at constant velocity relative to absolute space,
and then one ship accelerates until it is at absolute rest (in
physics, 'acceleration' means any change in velocity, so it can mean
decreasing velocity as well as increasing velocity). In this case, it
is the one that accelerated that is "really" at rest relative to
absolute space, and the one that did not accelerate is "really" moving.


Do you agree that in this scenario, it's the ship that accelerated that
is at rest and the one that remained at constant velocity that's moving?
