[edit] Time travel
I disagree that your argument shows there is a "logical flaw" in using the fact that a time machine couldn't take you back further than the date it was created as a possible answer to the question of why we see no time travelers--as long as it's reasonably plausible that there might not be any intelligent alien civilizations in our past light cone, then that is enough to establish it as a possible explanation. Do you think we can say with a high level of confidence that there must be intelligent alien civilizations with advanced levels of technology in our past light cone? What about the Fermi paradox?
Also, please look at Wikipedia's policy on original research--"original research" covers any original arguments not found in published sources, not just "research" in the usual sense of the word. Even an editor's own synthesis of arguments published in different sources is excluded under the policy. Hypnosifl 09:35, 2 March 2007 (UTC)
