I don't know why you were downvoted, the theories you referenced sound as plausible as any other to me (but then again I tend to assume everything comes with a touch of bullshit).

The situation you described would result in a game of universal pong, in which matter is passed from one side of the universe to the other before reaching a critical point where it bounces back. Obviously I have no means of validating the "Plank star beyond the horizon" theory, but nor can anyone else can prove differently at this point.
