Dear Thread,
A very interesting thread, no it does not help me understand string theory or quantum more clearly but it does help me understand the minds of the scientific community more clearly.
My theory and yes it is a theory, not your common or garden hypothesis, a strong theory, why! because of one glaring fact, scientists are................wait for it...............wait for it!! Human.
Whilst reading through Sanes opening link and trying to understand what all the chuntering was about ( oh and by the way I think that almost every post on this thread is covered in the article, I think ) this paragraph stopped me.
In my talk on the final day of the meeting, I argued that indeed physicists do in practice use undisclosed assumptions: aesthetic judgements that they use to select among approaches. Philosopher Elena Castellani recounts the history of string theory: “The theory was regarded as so beautiful and had such a compelling mathematical structure, obtained in agreement with consistency conditions and deep physical principles, that the intuition But why should beauty be a valid criterion for assessment?was that it had to be somehow related to the physical world.” The problem is highlighted by historian Helge Kragh who speaks about theories once considered beautiful but now considered wrong: the steady state universe, vortex theory, SU(5) grand unification.
The methods science use in evaluating any theory, any hypothesis are fine, the scientists who are just like us, are prone to all sorts of human failings, sorry, every sort of human failing.
Just because a theory is beautiful does not make it right, hell! I am beautiful but nine times out of ten I am wrong, but just like the scientists I will focus on the one time I am right, why, because I am human.
