That's my point: what experiments could be performed have been performed, and have failed.

Also, it is a massive weakness of the theory that it can be used to predict such varied values. This is a big part of why it is not exactly a scientific theory: it is not really falsifiable, since you can tweak it to predict any value you want. If we had the kind of particle accelerators needed to test high-energy supersymmetry, and if it failed again, it could be adjusted to predict higher-energy supersymmetry, and since the number line extends towards infinity, this would never stop.

I think you are correct, ST is closer to mathematical abstraction than an actual physical theory. I think that makes it more useful than less useful though.

[mensetmanusman]

Wouldn't that mean it is just more useful in mathematical reality but less useful in physical reality?

Can't you disprove string theory by disproving quantum physics?
