Advertisements I have zero problem with this. Why wouldn't it stay perfectly in the middle? You are watching a show about a dome that can survive a big bomb, not to mention cut a cow in half, and not even have dirt on it but you have a problem with an egg staying in the middle of the little dome? Somehow I would not expect ANYONE in that town to have any idea WHY it doesn't move. Now, the fact that no one has noticed, THAT I can see as an issue. They are awfully unaware of what is around them.
