Theoretical Physics, too, can drive experiment.
My main point really was that OP had a serious misunderstanding of what a wormhole actually was, and how it could be made. I doubt their existence because it's not even clear what goes on inside Black Holes, and a wormhole would be equivalent to a black-hole and "anti-black hole" pair. Even the latter objects aren't established as existing, so a combination of the two is even more extraordinary.
Furthermore, the energies involved in an object travelling at Mach 10,000, while impressive, turn out by my calculations to be far smaller in relation to the measure energy/area than those currently produced at, for example, the LHC or the recently shut-down Tevatron. Roughly speaking, if the Mach 10,000 object produces an energy/ area of 1, then the particle accelerators produce an energy/ area of 400 million times that.
Such energies would be at the very least far more likely to produce wormholes/ black holes than a mere fast plane.
