If we were to persue this subject matter with logic, if we looked at nature, like RBS and O'Ro are begging us to do, and adhere to that of the "laws of nature" then i ask you to look at 2 things:
The Circle
and
The Straight Line
The circle, the cylinder, however you want to view it is something that nature creates. Bubbles on a puddle on a rainy day for example. Some philosophers even scientists have long regarded the cicle as the "perfect figure", as the symbol of divine creation.
The straight line, however, is a very man-made notion. It epitomises us (there's a beginning and an end to us all) with our timeline's etc. It's finite and filled with clarity, but it's exactly what i just said: Man-made.
I'm just thinking logically. If the circle is nature epitomised then why can the universe not be cyclical?
I know that wasn't proposed before when we were talking about the curvature of space-time, but couldn't this be just as plausible?
To say the universe doesn't curve, but that it is just a big line (for arguments sake) would be a very narrow minded thought...quite that of the typcal human. It would be too man-made and the both the religious and aethiests out there can agree on this one together:
Man did not make the universe. [/b]
