[quote name='help1']I would record the winning lottery numbers for a year or two, and then travel back in time, win the biggest lotteries, and give my friends and family the other winning lottery numbers.[/QUOTE]
The problem with trying to win multiple lotteries (or any gambling for that matter) is that by doing your first big wins, you might impact the future in such a way that the future outcomes are different. Same thing with taking the history of the world back with you. It might be that the FIRST thing you do differently changes the entire thing, and your whole history is suddenly a worthless alternate reality.
