It should be pointed out also that, if stings are Planck scale entities, then while they are testable in principle, they are untestable in any practical sense, since probing to those scales would require an accelerator on the scale of the solar system. As Hawking put it, it's unlikely that such a device would be built in the current financial climate. :lol:
