I need some help to answer a question as my physics background, while self taught, still has some holes both from following only specifics and gaps since studying it. The question is below. "is there a reputable function for the effect of time dilation in special relativity or is just like a guessing thing. I always assumed that because of the way I think light works (again I'm a game theorist so I could be wrong) that it would have to approach an asymptote at some point. Just kind of curious about it after reading the Forever War by Joe Halderman. " Something about it smacks me as a relative mash-up just to mess with me. I'm just trying to answer this without getting it wrong.
