that is correct. the faster you go, the more time slows down. so if someone traveled at a very high rate of speed and made a round trip back to earth, they would come back to an earth in the future. basically if they left for a year, the time spent traveling that equaled a year to the traveler wouldnt equal a year back on earth....it could be several years back on earth equated to a year of travel in space. this is all assuming a very high rate of speed.
also, if you travel towards a black hole, as you get closer and closer towards the center, time slows down. so if you could somehow manage to circle a black hole for a long time and then come back to earth, you yourself would be from the past.
