Thread title edited to reflect the topic better, travel "near" c rather than "at" c
Hello all,
Suppose we can travel on a spacecraft at the speed of light, how long it would take for the person on the spacecraft to travel one light year, not to a person observing him/her from Earth, if there is any difference?
Thanks
