Objections to Tachyons
Dr. Tiwari cites the two main objections to tachyons in discussions published in Physics Today magazine in 1969. First, there was the contention that the notion of imaginary mass for tachyons raises questions about how the General Theory of Relativity (GTR) can be applied to them, so as to gain an adequate understanding of the role that inertia and gravitational mass play in tachyonic frames of reference. That is, the assumption was that only detectable changes in energy and momentum would be observable for tachyons, and the notion of the tachyon will therefore remain a mere theoretical curiosity as long as we do not know anything about how tachyons interact with ordinary matter and gravity. Secondly, there was the contention that the mere existence of tachyons would violate the "principle" of causality; assuming, of course, that it is impossible to violate this principle in any way, and therefore that tachyons do not...
