From: Stathis Papaioannou ...an infinite amount of subjective time can be squeezed into the last few moments of a collapsing universe This reminds me of a strange story I've learned long time ago. A dynamical system which passes through a succession of states, at constant time

Unfortunately, sensationalists articles that are completely baloney appear in most scientific journals from time to time. Nature published an article claiming that if the fine structure conswtant is changing, as suggested by some astronomical observations, then this change must be due to a change

I thought that quantum theory (in all its flavours and interpretations) *does* imply that reality isdigital. For example, if light is quantised, then the light reflected from a real object will produce a pixelated image, albeit far more finely grained than the image on any computer screen. The

I don't know anything about Afshar, but I do know that variable-speed-of-light (VSL) theories of quantum gravity are now being considered seriously by physics journals and by some leading physicists. Joao Maguiejo (sp?) has a popular book on the topic entitled Faster than the Speed of Light.

That's correct, but such theories can be mapped to theories with constant C. Ultimately only dimensionless constants matter, all other constants are just conversion factors. - Oorspronkelijk bericht - Van: Ben Goertzel [EMAIL PROTECTED] Aan: Saibal Mitra [EMAIL PROTECTED]; [EMAIL
