The Scale of the Universe — 1 Comment

  1. One thing I always try to emphasize is that space is three-dimensional and the solar system itself is two dimensional. Too often I see the planets laid out on a straight line, which doesn’t really give a sense of just how empty the solar system is. If a teacher has the room to have different planets laid out on the gym floor or a field outside the school in the different directions where they happen to be that day, it’s much more impressive.
