Spheres are 2D?
There are a lot of sportsmen who would disagree with you...
I'd give Buzsaw most of the credit on this question. It is only the surface of a 2-sphere that is relevant, and that surface is 2D space. The stuff contained in the "interior" of a 2-sphere is not real.
Buzsaw fails to get full credit because he refused to note that a 2 sphere is simply an analogy for the topology of the universe. I don't believe any of us can visualize the 3 spheres and 4 spheres. At least I know I cannot.
Perhaps part of the difficulty is that it is quite easy to look at a 2-sphere and to believe it is actually like a basketball, and to believe that a 3-sphere cannot possibly exist because there is no equivalent "extra" dimension to curve into. Of course that reasoning is complete hogwash.
I wish you guys the best with this endeavor. Buzsaw actually brags about not having been indoctrinated by university professors and their higher math and physics. That attitude wouldn't seem to bode well for a thread of this nature; a thread that belongs you now where. But I'm rooting for all of you.
