time travelling- is it possible ???
since when you go back in time, then you should see yourself , therefore a second you, and if you see him and he sees you, that means you have new memories, unless it is someone else you are seeing, so when going back in time you already have had to seen yourself, now does that mean faith exists or what??
here is another one, when going back in time, you kill yourself preventing yourself from going into the timemachine in the first place, thus making it also impossible that you killed yourself, since you are still alive after killin yourself in the past...unless there is a second you ???
