A superluminal signal A^B that is forward in time in one inertial frame may be backward in time A->B' in another inertial frame related to the first by a Lorentz transformation. Difficulties with causality only arise if a return signal B'^C is possible, where C is in the past light-cone of A. md5:00ce76cc4766996c2310fb2542657471	198.3 kB	Preview Download
