- pfdietz 7y agoWhat that says is that String Theory can predict anything, therefore it can predict the Standard Model. This is not a good look for a "theory".
- peteradio 7y agoThat's what I'm trying to get across, its not a good "theory" its a model factory. Forget the "theory" in string theory, its not predictive yet, but it will be once we have established the parameters of our low energy world well enough. What it does do, is define what a theory of everything probably looks like and that helps theorists agree on what proper measurements even look like.
- pfdietz 7y agoIf it allows one to predict anything, then it is totally useless. It doesn't help theorists do anything but extract $$$ from gullible funding agencies. The notion that "it will be once we have established the parameters of our low energy world well enough" is not supported by any evidence, unless you are saying "once we have given it the correct theory to imitate, it will imitate it correctly". A sheet of paper could do that, though.
