I read the article. I find the quote that I gave puzzling. I am looking for clarification from whomever might wish to do so. It means that if you have two objects let's say one stationary (earthbound twin) and another moving (the twin traveling in the shuttle), from the point of view of the one on earth the one in the shuttle is moving away, but in the other hand if you now see it from the one in the shuttle's POV then it's the one on earth that is moving away.
