<i>"Does this mean that if I were in a different galaxy other than our own, I would suspect that I am at the center of the universe? All galaxies are receding away from eachother correct?"</i><br /><br />Yes that is correct, although what we observe us more consistent with a model where galaxies group together into clusters due to their gravity, and it is all those clusters that are receding from each other.<br /><br />Our nearest neighbour, Andromeda, is actually moving <i>towards</i> the Milky Way, because the two galaxies are part of a gravitationally bound system. Our local supercluster of galaxies are all part of this system, but outside of our supercluster, all the other <i>(clusters of)</i> galaxies are receding from us. <img src="/images/icons/smile.gif" /><br /><br />It seems as if all the clusters of galaxies retain their relative position within the volume of space, but that volume increases in size, increasing the distance between those clusters.<br /><br />To visualize this, think of a volume of space with a grid of points in it, all 1m apart in each direction. If you put yourself on one of those points, whichever direction you look (up, down, left, right, backwards or forwards) you see your nearest neigbouring points at 1m, 2m, 3m, 4m, and 5m away.<br /><br />Now imagine the volume of space <i>and</i> the grid of points within it expands to 10 times its original size. Your nearest points will now be 10m, 20m, 30m, 40m and 50m away. So in the same amount of time that your nearest point moved from 1m to 10m away, the point at 5m moved to 50m away! Your nearest point receded by 9m whilst a further point receded by 45m in the same length of time and so that further point looks as if it is moving away a lot faster than the closest one.<br /><br />The further away you look, the faster a point seems to be receding from you, but if you put yourself on a different point at the start you would see exactly the same thing. Wherever you are, everything seems to be moving away f <div class="Discussion_UserSignature"> <p><font color="#ff0000">_______________________________________________<br /></font><font size="2"><em>SpeedFreek</em></font> </p> </div>
