Interesting Thought….

So someone was asking on the internet an interesting question.. Specifically, if they traveled back in time to 1000 AD what Technology or Theory should they know so they could change the world and make a difference.
During the post there were alot of the “Invent the Printing Press”, “Invent and Make Gunpowder”, and so on. Someone even recommended he start a business selling cats as home pets to fight the oncoming plague.
But then someone chimed in with something great…
“If you are transported back in time, then it’s already the case now (in 2008) that time slices of you existed in the past. Accordingly, we know already that you did not invent any amazing machines early, or, if you did, they didn’t catch on. (See David Lewis’s “The Paradoxes of Time Travel”.)
However, from this no particular practical advice follows, except that if you try to change history, you won’t succeed. ”
I just love that statement.. Basically putting the guy in his place that no matter how hard he tries to change the past, the past already existed and already knew of his changes and in such he can’t change shit…
