There is observational evidence for at least one branch. To say an epistemic interpretion implies there are no branches is a misinterpretation of epistemic interpretation, if not a complete strawman. > > > > Your claim that all branches are equally real is > > indeed a non sequitur, in that it does not follow from anything at all. > > Indeed.

Because it is a consequence of Solomonoff-Levi induction, sometimes known as Occam's razor theorem. In order to get to your "There is only one reality", you _have_ to add a mysterious something, call it what you will. My assertion is that that "something" is probably a figment of imagination. Nobody in 20 odd years of arguing about this has been able to point their finger at anything that will do the job. The closest I've seen is an appeal to Goedel incompleteness, that (if believed) would privilege the integers as something more real than anything else, but that seems to lead to an even deeper multiverse than the MWI. -- ---------------------------------------------------------------------------- Dr Russell Standish Phone 0425 253119 (mobile) Principal, High Performance Coders [email protected] http://www.hpcoders.com.au ---------------------------------------------------------------------------- -- You received this message because you are subscribed to the Google Groups "Everything List" group.
