I was thinking about this earlier. This a ridiculous and hypothetical question.<br />We have to make two assumptions:<br />1.(significantly) faster than light travel <br />2. a Telescope of this size.<br />Now, you take your giant telescope and your superluminal engines and head out, say, 10 lightyears. You then turn this giant telescope back to Earth and (somehow) see yourself building the ship!<br />Now of course, you can't do this, but if you could, it would be a great tool for studying history. Jump 200 lightyears away and watch Civilaztion develop.<br />make any sense?
