1/r^2 has a nasty singularity at r=0, but it did not bother Newton-the Moon is far enough.

One of the basic things about a string is that it can vibrate in many different shapes or forms, which gives music its beauty.

One very important aspect of string theory is definitely testable. That was the prediction of supersymmetry, which emerged from string theory in the early '70s.

The theory has to be interpreted that extra dimensions beyond the ordinary four dimensions the three spatial dimensions plus time are sufficiently small that they haven't been observed yet.

There is a difference between knowing what is true and knowing why it is true

M stands for Magic, Mystery, or Matrixaccording to taste

So when you ask me how string theory might be tested, I can tell you what's likely to happen at accelerators or some parts of the theory that are likely to be tested.
