I just started the Elegant Universe which is about string/superstring theory. Now, I haven't gotten that deep in, but I've looked up some of it on Wikipedia, and according to what I can see, there has ...

The goal of elementary particle physics is to achieve a unified understanding of fundamental forces (gravitational, electromagnetic and nuclear) and elementary particlesin terms of concise and ...

Few fields of scientific endeavor are “hotter” than superstring theory. Despite a debate that has broken out between theoretical physicists over the substantiality of the field (see “Opinion,” page 9) ...

No. And testing for them is... problematic. Recently, there was some hope that short-range gravitational measurements (like, within a cm), might show deviation from longer-range measurements, giving ...
