>>>Talking of slow light, how come space cruisers rumble past the static observer, at about 10 mph, but are supposed to be travelling at space flight speeds?

>Note I said "static observer". I wouldn't mind if the stars were moving for us, the observers, and the ship's doing just 10 mph more than us, but that's rarely the case.

The stars only seem static. Their movement relative to the camera, however, is recorded below one pixel per scene. So I don't mind that - and there's enough of other stuff to tally.

Like the abundance of gravity in space :).
