Sorry to be a geek, but a "light-year" is a measure of distance, not time. ![Smiley :)](https://www.carls-sims-4-guide.com/forum/Smileys/default/smiley.gif)
True, but considering she died at the age of 90 and had travelt 350 light-years (for example) she must have travelt at the speed of light, or faster, if possible. Otherwise she couldn't have enouth at 'just' 90 years. Do that and you will change the space-time continuum, according to Einsteins theories.
I think that's what Samoth was actually saying.
