A Disc of Cosmos

10/22/2006 2:01 AM

see, all the radii of all the stars, planets, moons, etc. lie on the same plane. right?

so, can we safely say that the universe is more of a disc in shape... than being spherical??

what say?

The solar system's planets are only roughly in line, +/- 10 degrees or so....

No the comos is not disc shaped otherwise what we would see in the sky would be a thin line of light from stars, galaxies etc...

Assuming we were part of the Cosmos! As we can see stars all around its fairly safe to say that the cosmos is spherical...

Unless you start to think about curved space and time etc...

There is evidence that the universe is slightly ellipsoid in shape.

Look at a deep space photograph of distant galaxies and you will see that they are aligned in all different alignments, not simply edge on as you proposed.
