Took me a minute to decipher.
If I understand correctly, the theory is basically that the Earth consists of approximately 4 quadrants, all experiencing a different part of the day at the same time. So each day on the Earth is really 4 days.
Then somehow points of light from the sun are added up to arrive at a sum of 96 hours in each day. This doesn't make sense to me.
I rate Time Cube as: insane. I also love it, in a way. The spectrum of humanity and the ideas contained therein is colorful and vast. Remains to be seen what difference it will all make in the end.
