Euclidean geometry?
Parallel lines?
Great album by the way!
I'll have to wait until I come back to delve into these deep philosophical debates. I was an ace in Geometry at one time. Though it seems Euclid didn't anticipate the curvature of space around high mass concentrations/bodies/points. And come to think of it, I wonder what the "space" was like in the instant prior to the big bang. Some say there was none, it was all wound up tighter than a progressives' definitions of acceptable politically correct speech.
