nen888: You're absolutely correct that string theory has a solid mathematical foundation. It is the ongoing result of a great deal of earnest work by many well-respected theoreticians, and I would never dispute their efforts or their sincerity. It's just that mathematics is a tool that can be manipulated (or innocently used) to support erroneous conclusions in addition to, or mixed in with, truth. And truth itself is a frequently changing --and very possibly localized-- phenomenon. Time will tell. Heh, that's why I hang out ... in the TimePantry. Plus, the food is awesome.
synchroneyes: Thanks for your support; I feel I should quote Buckaroo Bonzai here, but I can't think of a good one. That is a very thought-provoking point about perception being relativistic. My instinct is that it would have to be. And I don't think we can fully perceive our system, we have only the data from our POV. (Well, and the view from hyperspace.)
nen888, since you asked, I'll talk a bit about a recent thought I had in spice mode:
As you know, there was at one time a question regarding whether light was a particle or a wave. Think about it -- a "wave" is a thing attributed to liquids, usually liquid water. Yet a water wave
is itself made up of particles! Is there any such thing as a wave that *isn't* made up of particles? So, perhaps is isn't really useful to think of them as two separate things. When the particles in a liquid are making waves, they are exhibiting a particular behavior peculiar to waves, yet they are still particles. But while they are being waves, are they still discrete individual bits of hydrogen and oxygen? How many electrons do two atoms have to exchange before they are not quite two separate things anymore? (Ah, the Ship of Theseus! Big fun!)
