An Introduction to the Theory of Tachyons
arXiv:1112.4187
Abstract
The theory of relativity, which was proposed in the beginning of the 20th century, applies to particles and frames of reference whose velocity is less than the velocity of light. In this paper we shall show how this theory can be extended to particles and frames of reference which move faster than light.
