Hi brellis! I have been lurking a bit recently, posting now and again when a thread comes up that I think I may have something positive to contribute to. <img src="/images/icons/smile.gif" /><br /><br />I feel responsible for helping to divert this thread towards the anthropic principle (but in answer to others posts) so to get back on topic:<br /><br />Another way of looking at time, or the question of whether time actually exists.<br /><br />Does space actually exist? What actually is it? What is it made of?<br /><br />We can only measure the passage of time using chronometers calibrated in our own arbitrary way, in the same way we can only measure a distance of space using rulers calibrated in our own arbitrary way.<br /><br />When it comes to space we cannot say that the space itself exists as an actual thing, we can only attribute <i> distance </i> to it. This is exactly the same as time, where we cannot say it exists as a thing, but we attribute <i> duration </i> to it.<br /><br />Space itself (in the purest sense, let's ignore the things that may or may not exist within space) is emptiness, void, nothing. So does space actually exist? I would say, in this context, that no, space does not actually exist. We just see evidence of space by the dimensions it presents to us. Just as we only see evidence of time by the durations it presents to us.<br /><br />Just as time can dilate when travelling at a relativistic speed, so can length contract. Both time and space are dimensions that are intrinsically linked and one exists as much as the other does. <div class="Discussion_UserSignature"> <p><font color="#ff0000">_______________________________________________<br /></font><font size="2"><em>SpeedFreek</em></font> </p> </div>
