time travel is a totally a different topic.i agree with what u say in the first part of ur post....about our future looking like zombies.but how can they come back in time and see something that is long dead and gone???okay,if u're talking about entering somebody's memory and going back in time into a virtual world,it's fine with me.time travelling into a physical world....?i don't think so.
