>No, I mean, a 2D circle could appear as a line from a certain perspective in 3D space. Right, and as a matter of fact that's exactly what we DO see with the Milky Way galaxy. It can be conceived of as a circular disc, more or less, but in our sky we see it from the side, as a streak or a band rather than a disc. |
