TIME TRAVEL <br />time is so intricatly interwoven with space that if time and space are pulled apart the universe will collapse to ultra thin sheet of one dimension which is nonexistent. To travel against time whether in past or future we have to separate us from time which is not possible.
If you're thinking of a black hole, the collapse to one dimension would exist as a single dimension of space with the other dimensions as time, (which can be thought of, as nonexistant). In other words, the 4 dimensions of space and time switch places.<br /><font color="yellow"><br />To travel against time whether in past or future we have to separate us from time which is not passible. </font><br /><br />Just to be clear, did you mean passible or possible? <div class="Discussion_UserSignature"> <p><font size="4"><strong></strong></font></p> </div>
Are you implying that a one dimensional space is something that is nonexistent?<br /><br />Giving it a dimension of 1 (the left, right dimension) is giving it some sort of existence. This is one of the fundamental ideas behind string theory. A one dimensional being, in a one dimensional universe, is unaware of other dimensions that could very well exist. For example, a second and third dimension (forwards, backwards and up, down). <br /><br />It's hard to say whether or not it would unmake the universe if a person purposely left the timeline to either jump to the future or past. <br /><br />You must first understand all possible theories as to how time travel may take place. Consider the parallel universe theory. <br /><br /> <div class="Discussion_UserSignature"> <p> </p><p><strong><font color="#ff0000">Techies: We do it in the dark. </font></strong></p><p><font color="#0000ff"><strong>"Put your hand on a stove for a minute and it seems like an hour.

I do not imply that one dimension space (sting theory) is not possible, but the time travel is. The way we are talking about traveling past in time and creating a paradox by killing our own forefather produces many doubts. Does the past, present and future exist togather (parallel universes) ? And if it is so, we must have a well determind future and the universe must be deterministic. We can travel back up to big bang or beyond or can travel to future to any extent!
