I was talking with some friends today about the universe and I suggested a theory of mine that the universe is like a sphear rather than a flat plane or other shape. I did a little googleing and found out that this was not a new idea. There’s more support for a flat universe, but I still like the idea. This is what NASA has to say about it…
“The density of the universe also determines its geometry. If the density of the universe exceeds the critical density, then the geometry of space is closed and positively curved like the surface of a sphere. This implies that initially parallel photon paths converge slowly, eventually cross, and return back to their starting point (if the universe lasts long enough). If the density of the universe is less than the critical density, then the geometry of space is open, negatively curved like the surface of a saddle. If the density of the universe exactly equals the critical density, then the geometry of the universe is flat like a sheet of paper. Thus, there is a direct link between the geometry of the universe and its fate.”
