section two: The Stephen Hawking Memorial Lecture.

Sometime in the 1990s, Stephen Hawking mentioned that he was working on a theory that treated space as if it was imaginary time. My thought at the time was that as he was so close to finally solving this gravity thing of ours, there would be no need for me to ever even get involved. Well, the poor lad made no further progress and eventually he died. In 2007, I decided to finally get off my high horse and take over from where he had clearly got stuck because this subject is not even very difficult. Well, I do admit that it might at first seem difficult for ordinary minds, however, our men of gravity, Aristarchus of Samos, Copernicus, Galileo, Newton, Einstein, Eddington, Hawking and myself do not pay any attention to ordinary minds.
