has anyone ever heeard of the butterfly effect? its from a story that this guy goes on a tour in prehistoric times and steps off this platform that they have and steps on a butterfly, when he goes back to the future, instead of it being a free and prosperous society, it becomes a land that is ravaged by famine and is under communist rule.
if i went back it would be to bring one of the people from around the 1950's or 1940's to here and see the look on their face. then i would wipe his memory because he cant know all this stuff and send him back. im assuming that if we have time travel, we can wipe memories.
