^yea, you need an infinite source of energy to get to and past the speed of light, otherwise the mass or whatever is going would collapse on itself, i believe thats how it works...and so far there isnt an infinite source of energy like that to provide a spaceship 20 years of travel etc. all that, but yea in earth years it'll be the same from you related to the traveler but to the traveler it will seem a lot different if you were in the ship and shits
