Can't get enough of the World

I can not get enough of this commercial... it is less a commercial about the Discovery channel and more about how awesome our world is (which is kind of what the Discovery Channel is about..hmm). Anyways.. I sing it all day.

So.. I was thinking about movie time travel today (because.. you know.. I'm a geek). So.. terminator time travel doesn't work. The whole movie's idea is that we make our own fate, but things are predestined (the savior of the human race sends his buddy back to be his own dad. Its a self referencing loop..so..no go). Now Back to the Future time travel works okay (except for the fading Marty which is lame and doesn't make much sense).. everything Marty does in the past retroactively effects his future. The only problem is that Marty_A goes back.. affects his parents and future.. parents have Marty_B.. then Marty_A returns to the present. He thinks that he is seeing himself go off in the Delorean but Marty_A is really watching Marty_B go off into the past. So where the hell does Marty_B go (presumably back in time..affecting his parents future resulting in Marty_C and so on). The best thing for Marty_A would be if Marty_B never makes it back his past.. Marty_B goes to the Permian period and got crushed by a Dimetrodon. Apparently this doesn't happen because as soon as he gets back to the present, Doc takes him to the future with those nifty hoverboards. Who the hell is this future Marty? Is this Marty_C perhaps? Marty_B must have gone back.. got his parent together and instilled positive thinking in them.. and then took his trip to the Dimetrodon footwear store. And this Marty_C didn't hang out with Doc and go back in time (his 1985 was pretty good now). Sooo.. Marty_A and the Doc go to the future to help out Marty_C's kids? How weird is that.. and why do they care..if thing aren't predestined (as shown by new and improved McFlys of 1985) what can you possibly do in the future (accept buy cool new toys that affect your past)do for you? Marty_A couldn't have been seeing himself in the future, because he removed himself from the time stream. He was looking at some alternate Marty that really wouldn't be him (good thing he learned not to be such a hot head though..way to avoid that car crash that screwed up Marty_C's life). So.. the movie's time travel works with a minor paradox and some missing information.

Lets assume that the law of conservation holds true.. we can't create or destroy matter.. there is a finite amount of energy in the universe. So.. as Marty_A makes Marty_B with the time machine, some small star.. or guy in Cleveland.. or a school of mackerel.. dematerialize to make up for the new Marty_B (We've made a machine that not only displaces matter though time, it also redistributes energy in the universe (I'm thinking the flux capacitor..king of black box technology.. makes this work out ).

Wow.. while thinking about this, I did a Google and this guy's website hits these points and a lot of other movies more thoroughly than I do (but less humorously I'm sure).

There is a movie that did time travel really well and I can't remember the time.. its like.. hmm.. machine.. mechanical term.. torpid.. Primer!!! Wow.. witness my brain in action!! Not sure where torpid came from but it brought forth Primer. If you want to watch a very nerdy movie that is only enjoyable if you're a nerd (and awesome in that right) watch Primer.
