Thanks, Russell, I really do not want to continue - seems side-line to you and side line to me. I just cannot keep my mouse shut.
1. The 'nonequilibrium' topics still identify a certain 'cut' within the boundaries of them, neglecting wider - maybe unobserved/able - effects from 'unrelated' sides. (see my '3' below) Pertinent to 'closed systems' as well. In (my) wholistic view nothing is shut of of anything in an intereffectiveness that may include unknown elements at the level of our present cognitive inventory. 2. Suppose singularity is "not" - where does the (alleged) GR break down? It is a 150th consequential idea from a questionable startup-figment and we just continue to build logically, quantitatively, formally - call it science. To be clear: I appreciate and USE the technological marvels based on such questionable theoretical background. I believe in human ingenuity even on wrong premises. 3.To your last par: one cannot have it both ways. Einstein (what a comparison to myself!!!) did not accept all Newton in his thinking and tackled only certain terms in a new view. Copernicus did not abide by the well proven Flat Earth and just 'included' at some points his new ideas. You cannot keep creationism when you think in evolution. I may get lost - as you say - but it won't last long. I won't either. In the meantime I have the luxury of tasting the new ideas. And I feel I am not alone in these ways John M ----- Original Message ----- From: "Russell Standish" <[EMAIL PROTECTED]> To: <email@example.com> Sent: Wednesday, May 10, 2006 2:01 AM Subject: Re: why can't we erase information? > > On Sat, May 06, 2006 at 10:24:05PM -0400, [EMAIL PROTECTED] wrote: > > > > Russell, > > my apologies for the "approximate" typing.
