Special relativity offers the possibility of shortening the travel time: if a starship with sufficiently advanced engines could reach velocities near the speed of light, relativistic time dilation would make the voyage much shorter for the traveller. However, it would still take many years of elapsed time as viewed by the people remaining on Earth. On returning to Earth, the travellers would find that far more time had elapsed on Earth than had for them (twin paradox).
