I don't know much about the TOR but it is certainly detectable what's stationary or moving when two objects are flying around. In perfect conditions, light will travel at ... the speed of light.
Suppose the two objects are balls of light. Each of them starts emitting at the same time.
If the one of the balls is moving, at a low or high speed, the light will lag behind it.
If a human were observing from a node attached to and in front of the ball moving at the speed of light, and the light suddenly turned on, it would take a bit of time for the light to catch up with him.
The Earth is in motion by many parts: its motion in orbit, the sun's revolution around the galaxy, and the galaxy's motion through space. In reality, it takes longer for light to reach the earth from the sun during certain parts of the year.
