Time, we know, is relative. You can travel light years through the stars and back, and if you do it at the speed of light then, when you return, you may have aged mere seconds while your twin brother or sister will have aged twenty, thirty, forty or however many years it is, depending on how far you travelled. This will come to you as a profound personal shock, particularly if you didn’t know you had a twin brother or sister. The seconds that you have been absent for will not have been sufficient time to prepare you for the shock of new and strangely distended family relationships when you return.
