Query: Strings, Black Holes and Lorentz Contraction   Consistency of quantum mechanics in black hole physics requires unusual
Lorentz transformation properties of the size and shape of physical systems
with momentum beyond the Planck scale. A simple parton model illustrates the
kind of behavior which is needed. It is then shown that conventional
fundamental string theory shares these features.
