Saving time

Over at Orbiting Frog, Rob talks about relativity and the Universe's insistence that time runs more slowly for objects that are moving quickly relative to an observer at rest. The effect is tiny for the speeds humans travel at and is really only significant as you start to get close to the speed of light (which, incidentally, we haven't got anywhere close to with passenger transport). Anyway, Rob has built a calculator so that you can work out just how much younger you are, due to flights and cross-country road trips, than you would have been if you had stayed at home. The difference is measured in nanoseconds (billionths of a second), so don't expect this to be marketed as a serious anti-ageing solution.
