As there doesn't seem to be a consensus on whether relativistic Turing machines can actually exist, I'm not sure this constitutes a proof (though the paper itself is beyond me). The idea of relativistic Turing machines is fascinating, however: "... we might [through clever application of General Relativity, likely involving black holes] be able to speed up the time of one observer, say C (for "computer"), relatively to the other observer, say P (for "programmer". Thus P may observe C computing very fast ..." [0] But (from another source) "... all these claims rely on the provision of one or more unphysical resources ..."
