That wouldn't quite do. Just simulating this planet takes a lot of hardware. Just because you can write down Navier-Stokes it doesn't mean rivulets, streams and oceans spring into being. A little more work is required for that. > It seems to me that mathematics exists without the mathematician. To me it seems the opposite is true.

While I'm open to existence of a metalayer, built from information or otherwise, I'm very much opposed to mysticism. -- Eugen* Leitl <a href="http://leitl.org">leitl</a> ______________________________________________________________ ICBM: 48.07078, 11.61144 http://www.leitl.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE http://moleculardevices.org http://nanomachines.net
