When I first saw this video, I thought I had a very good grasp on the scale of things in the Universe. But the scale of planets, galaxies, clusters and superclusters, as presented in this video, is simply too much to grasp. If you can understand it, then treat yourself to a mint.
We hear astronomers babbling about ... |

One of the most remarkable, yet unproven, tenants of the currently-accepted model of the Universe is that the entire Cosmos is geometrically flat. This may be a consequence of the fact that the entire thing is expanding at an ever-accelerated rate, but thus far no one has produced clear evidence of this. When astrono... |
