I just wanted to know whether time dilation is different from time travel or not. Personally I believe both are different. If they are the same things I just wanted to know why. According to me time dilation is something that applies for every object, while time travel particularly applies for humans. Moreover I feel that travelling through time also in a sense means being able to control time. Time dilation is just an effect due to special relativity and I think it is often confused with time travel. Time travel can be based upon time dilation but I do not think that it completely implies the same thing.
EDIT By time travel I mean like exact travelling. Like you can go in any direction. Similarly I mean into the past as well as the future. But I just wanted to know if there is a general difference since everyone could define time travel in a separate manner.
