Self explanatory question I hope.
There ain'ta no sanity clause, and there ain'ta no centrifugal force Šther.

Well, while string theory is in agreement with other theories it can't be regarded as invalid, for it is as equally valid as the other theories with which it agrees.

For string theory to supplant those other theories though, it would need to successfully predict something that they don't.
...And its claws are as big as cups, and for some reason it's got a tremendous fear of stamps! And Mrs Doyle was telling me it's got magnets on its tail, so if you're made out of metal it can attach itself to you! And instead of a mouth it's got four arses!

Smaller scales require higher energies.  If you exponentially scaled up the LHC, you could get to scales where the effects of the  strings become observable.  Such a test would be completely impractical with current technology, however.

As I see it superstring theory in all its ramifications coupled together into M theory effectively describes all possible universes with physical laws vaguely similar to ours so the problem is not to prove it generally but to try to identify from which part of the vast range of possibilities our universe originates and why.
