Then one was flown around the world on a jet airplane (so we're talking no more than 300 m/s, when c is 300000000 m/s). And at the end of the trip, the clock on the airplane was some minuscule fraction of second slower than the clock fixed to Earth. So time dilation works even at very small speed. > >"So let me get this straight...You want to fly on a magic carpet to see the >King of the Potato People and plead with him for your freedom, and you >think >you're completely sane?" > >Rimmer, Red Dwarf > > Totally off topic: we don't get Red Dwarf here in Italy.
