The problem I have with saying that we travel into the future by achieving a high percentage of the speed of light is not the same as controlled time travel. He says that it is the past that we wish to see, where I would much rather see the future. The problem is a matter of controlling time, or time travel. Relativity might play games with the image you will see, but will you actually have an extreme time dialation or will you just have the appearance of the ship be a matter of visual properties (thus discussed in Star Trek). I have a problem believing that a single timeline exists as to where time travel is only assured if it follows simplistic laws of light. That's just me, maybe.
