plugging some quick numbers into wolfram alpha, the energy required to propel a 100 metric tonne ship to 99% the speed of light is roughly 5.472×10^22 joules. this is equivalent to 1/9th the energy of the asteroid impact that killed the dinosaurs, or 225,000x the energy of the tsar bomba, the largest nuclear bomb in history. which is to say, sedna's being a little optimistic in her dream here.
