Faster-than-Light Particles: A Review of Tachyon Characteristics.
预测了尚未发现的超光速亚原子粒子（快子）在不违反狭义相对论的前提下必须具备的一些特性，并讨论了快子与反重力之间的潜在关系。
This report documents an analytical prediction of some of the characteristics which presently undiscovered faster-than-light sub-atomic particles (called tachyons) must possess if they are to exist without violating the Theory of Special Relatively. A brief review of necessary concepts from the Special Theory is included so that the reader might more readily understand the reasoning as it is developed. Necessary, but not all, characteristics of tachyons are then identified and presented. Finally, an interesting potential relationship between tachyons and anti-gravity is discussed. (Author)
