Time Travel

Watching a show that will remain nameless (in case you DVRed and haven't watched yet) got me thinking again about one of the things I am most sure about in the world. The viability of travelling back in time.

Here is the thing about timetravel. You cannot go backwards. My theory on this is, in my humble opinion, infallible. If it were possible to go backwards, someone would have come back to now or a time before now, and we'd all know it. Basically, it will never happen because there is no current evidence that it ever, at some point in the future, will.

I know that makes me sound like Charles D. Buell, from the U.S. Patent Office who supposedly said (but actually didn't) , "Everything that can be invented has been invented". When it comes to time travel, though, this seemingly narrowminded view almost has to be true. Lets say, at some point, backward time travel is invented. You are telling me that no one tries to get to 2009 or before, ever? Once time travel is invented, it would ultimately be mass produced and made available to someone who wanted to see the birth of Christ, go to Woodstock, or see Julia Roberts nekkid. Someone would come back here. No one has.

If tomorrow you told me that the sun was a mirage, I'd been less skeptical than I would be to hear you'd invented a time machine that (and this part is important) could go backwards.
