On Complexity: after you've read a while you'll discover that there may be a highest complexity principle in play in _this_ universe. This goes with physics, math and all else (astronomy incl.). This highest complexity is thus given for each descriptive component out of everything and exhaustively covering everything this component can possibly describe. Therefore, the Universe is not inifinitely complex. No, it has a highest complexity prinicple to it, regardless, I think this covers all aspects given by each and every aspect by themselves and potentially for all human beings have the possibility to describe! Good?
Note on Cantor and related: it's not complex to utter that simply because you have an infinite scope of numbers running or a scope you certainly will not get to know by experience that this scope is complex because it holds "a lot". No, we are only concerned with the complexity of formula and usually people begin to insert probability calculus into the equations (by Boltzmann or so) and think that this is complex and they're RIGHT. This is one expression of complexity we're looking for in addition to other complex patterns of nature, including of course, the mathematical formulas and wordly descriptions of all else! Cheers!
