- Only in a strictly logical sense. But experience has taught us that
- consistency is, in practice, a very powerful guide in high-energy
- physics. Chris Lewellyn-Smith (I apologize for the spelling - I never
- can get the name right), the new director of CERN, is famous for,
- among other things, demonstrating that you can "derive" the Standard
- Model from nothing more than trying to build the simplest consistent
- theory that includes all the particles we know about - all the wonderful
- details of how they interact fall out of the model-building process
- as you try to avoid unphysical results (non-unitarity) and inconsistency.
-
- It is widely believed (or perhaps hoped) that the ultimate theory of
- everything will be unique in the sense that it is the only constructible
- theory which is mathematically consistent at arbitrary energy. In a
- certain sense, the entire theoretical program of HEP is an attempt to
- construct at least one entirely consistent theory (something that has
- *never* been done) of fundamental particles, which we then hope will
- be the *only* possible one.
