The first problem is this... how to build a time machine. If you're not able to build the time machine, then the rest are non-starters.

This is a giant paradox which makes the movie terminator such a great movie... (assuming youve seen it) John Connor sends a man back in time to save his mom and the man ends up being his father... How could John Connor exist until he sent his "dad" back in time... basically, which came first? the chicken? or the egg?
