Re: New Paper by Thomas Hertog and Stephen Hawking
Happy NewYear, Colin, you just came up shy from the notion that all this is a part of the anthropocentric maze. Physicists' hegemnony over (scientific?) thinking is embedded into the math-maze of numbers and this, too, may be a human invention (according to D. Bohm). So all the 'stories' and conclusions (including Russell's 'Occamistic simplification') are products of the human mind - not a 'MUST believe' for the existence we are part of. All is included in your 'perceived reality' we have access to. We are handicapped into our human limitations, tacitly we should accept that. Of course we cannot step out of our borders, but as a consequence of thinking 'human' we should be cautious when drawing ALL_generalized conclusions. We don't know 'what else' is going on. Even limitedly (distorted?) what we are concerned with. Everything is more than the everything we can imagine.

This will correlate to some notion of simplicity under Occam's razor. Then it is probably coupled in this case with giving the right answer. Of course it is always possible that it will be found wanting tomorrow :). -- Prof Russell Standish Phone 0425 253119 (mobile) Mathematics UNSW SYDNEY 2052 hpco...@hpcoders.com.au Australiahttp://www.hpcoders.com.au -- You received this message because you are subscribed to the Google Groups "Everything List" group.

A million other descriptions, also constructed by humans, could be as predictive of how the universe appears. What extra belief system must exist in order that someone conclude that we 'must' chose a "sum of all histories" as "the" story? Why is the universe compelled to be such a thing?

New Paper by Thomas Hertog and Stephen Hawking
Described in this article: http://www.bioedonline.org/news/news.cfm?art=2617 "This summation of all paths, proposed in the 1960s by physicist Richard Feynman and others, is the only way to explain some of the bizarre properties of quantum particles, such as their apparent ability to be in two places at once. The key point is that not all paths contribute equally to the photon's behaviour: the straight-line trajectory dominates over the indirect ones. Hertog argues that the same must be true of the path through time that took the Universe into its current state. We must regard it as a sum over all possible histories."
