WOSSNAME'S THEORIES ON TIME TRAVEL...
1. Time travel is not possible because Einstein said that it is not possible to either create or destroy matter.
Thus, if you try to go back in time you are both destroying yourself from the present and creating all your atoms at some point in the past. Assuming Herr Einstein was right, of course.
2. Failing that why doesn't someone tempt someone from the future to prove that it is possible...
I think a big country with sh*tloads of money (Like the USA) should do a large announcement that would make a large impression in the history books... (perhaps engrave this message on the surface of the Moon with a laser...) "The USA hereby declares a prize of $10,000,000,000 to the first person that proves time travel is possible by landing their time machine in the middle of Time Square. (nice irony huh!) At the winners preference, the equivalent in real estate ground space could be awarded.
That should take care of future exchange rates and should be worthwhile to anyone in the next 1000 years or so!
What do you guys think?
