Game 4 - The Great Debate

This game will relive the Great Debate of 1920, which attempted to explain the very nature of the Universe. Around this time, there were these fuzzy patches in the sky and nobody quite knew what they were. There were two opinions at the time:

1) Fuzzy patches were spiral nebulae in our Galaxy and our Galaxy comprises the ENTIRE universe.

2) Fuzzy patches were spiral nebulae that were ENTIRE GALAXIES separate from our own. These were so-called "island universes".

Two groups argue about this in front of an audience of professional physicists and astronomers. The primary combatants were Harlow Shapley and Heber Curtis.
