We continued exploring the scale of the Universe. We started by discussing space flight, and how the farthest human beings have been is the far side of the Moon. We reviewed the light year, and looked at the distances between various Solar System objects. Jared realized that compared to the light year, the Solar System (from the Sun to Pluto) is really not that large in the big scale of things. We also talked about Voyager I and how it has recently left the heliosphere. This is all groundwork in anticipation of covering the size of the whole Universe, how far it has expanded since the Big Bang.
