We all travel in time. During the last year, I've moved forward one year and so have we all, at the rate of 1 hour per hour. Can we travel in time faster or slower than 1 hour per hour? When you move through space-time, especially when your speed relative to other objects is close to the speed of light. Time goes slower for you than for the people you left behind.
Theoretically yes, but we haven't found out how to bend time & space just yet, I am sure we will have found a way in the near future(I personally believe about the USS Missouri or something like that, about how it was in Norfolk, Virginia, and got lost & reappeared like 70 years later in like NY).
