<p>bigmike, I’m familiar with Einstein’s theory of relativity and the “travel the speed of light” space journey example. I’ve already mentioned them twice in my posts, pre-empting the obvious responses I would get, but apparently not pre-empting enough.</p>
<p>Simply, it is not ‘time travel’ at all. And “changing” time is only perceptual.</p>
<p>The dumbed-down gist of Einstein’s explanation, is that, while traveling at the speed of light, an atomic clock (the most accurate measurment of time - allegedly) actually slows down relative to a clock not traveling thusly, i.e. on earth for example (this is because an atomic clock uses particles of light bouncing to and fro sensors - and the distance that particle/wave has to travel is longer when traveling at the speed of light).</p>
<p>And actually, all distances anything has to move perceptually become longer, as a result, all movement of particles slows down to travel same perceptual distance.</p>
<h2>So basically, assuming this “slows you down” by a factor of 2 (let’s say) you can “time travel” (not really) by traveling at the speed of light (say around earth, whatever) for ten years – although you will only have perceptually experienced and aged 5 years. So in 5 “perceptual” years – it will be 10 years later. But REALLY, you’ve still been doing stuff and are actually 10 years older. True time can never be altered (although perhaps it cannot be accurately measured).</h2>
<p>And gotakun - yes, if you want to claim someone is using a logical fallacy, that actually has merit and is understandable. But if you’re saying someone’s argument is wrong because it uses poor logic - you are basically saying the argument is poor becase it is argued poorly - in essence you’re saying nothing at all. And my ideas are my own — sorry there’s some intelligent thought around here.</p>
