Is Time travel possibly? I would say it is, but not the wat we would think it is. Lets say that everything in existence is against a wall moving slowly across a line which is time. (of cource this wall actually is intangible and is more of like a force then anything physical) everything is being pushed along this line at close to the same time, few things are able to slow or speed up the process of the wall. Gravity can slow it down but not necessarily stop it. If we somehow removed this walk from behind ourselves and the rest of existence moved on without us, we would be left in emptiness, but at the same point in time. Now if we found away to move along the line of time the only time we would ever be with anything is if we were where we should be. Saying this for all I know everyones “wall” so to speak could be going different paces, so how would we all see eachother, my guess is we are only effected by anyone or anything that is in a very clise range of us on the time line, this could negate my previous theory of being left in nothing and actually just end up on some elses wall that could be completely different grom our own. I call this theory the WAL theory it stands for Wall Of Life. (I am not the greatest at explaining please feel free to ask me questions)
