Time travel is impossable. you cannot "travel through time" because time is intangible. Time is not a relm or a dimension. Time is a concept. It is a concept designed by early man as a way to track and orient hisself with the daily movements of the earth. The passing of events is what man knows as time. Man also devised the hour, minute, second, millisecond, nannosecond and so on and so forth. These are used as a measure of the concept of time. Therefore, you cannot travel into something is a concept. Also, look at it this way. Our only link with the past is our memory of it. And the only link to the future is predicting certain aspects of it by information that is happening now. what happened a few hours ago is gone. no more. there is not a " place" to travel to. when a moment in time passes by, it no longer exsists. how can you travel to somewhere that doesnt exist, or hasnt existed yet?
