Look at this video:
http://www.youtube.com/watch?v=8Q_GQqUg6TsWhat do you think? Other than the fact that the 4th dimension isn't considered "time" anymore, and using the analogy that a 2-dimensional character could see (you could not see any if you were a 2 dimensional creature), it's very interesting.
The first part of the video is quite accurate. However, while time is often considered the 4th dimension, it is not the 4th spatial dimension.
And there are issues with time travel concerning conservation of energy/mass.
