mhmm... okie, someone please give larz conduct point too for going beyond the debate

I'm pretty sure I get your point that it's possible for the Earth to be a 4d shape that appears like a sphere in 3d. I'm also pretty sure that, since the universe is 3d, the Earth is not a 4d shape. Just as a circle is a circle in 99 dimensions, so is a sphere a sphere in 4 dimensions.

Thanks for being so patience with me, and sorry for the multiple post, but i really want to understand this.
When you say "appears" wouldn't the reversed also be true; what we perceived isn't what it is but what it appears to be. since we are 3D beings, our actions are limited to 3D plane. (the figure in the 2D plane could only interact in 2D when we pass a 3D object through it. likewise, a 4D object passing through our 3D plane could be interact in 3D)
the circle in all dimension is another concept i fail to grasp, consider the 2D paper ver as, a cone when passing through tip first would only appear as a circle, likewise, a sphere passing through it also appears as a circle. hence, it is impossible for a 2D figure to distinguish these two. consider now the 2D is our 3D plane, what we see as a sphere might not be a sphere in the 4D indeed could not be since it does not grows or shrinks in size.

My point is that the Earth is still shaped like a circle in all dimensions. It merely appears different.

Just a clarification, our eyes do not have the capacity to see in 3D, thus a 4D sphere would appear as a sphere growing in size before shrinking again as it passes through our 3D plane. A 4D cube (hypercube) doesn't appear as a cube. wiki has a good illustration on how this works http://en.wikipedia.org...

Wait what? we are 4D objects?
what i thought was that we are 3D, sees in 2D, living in a 4D world. Going back to the paper analogy, the figure on the paper is 2D, living in 3D and sees in 1D (ie, sees lines of varying length and shades). http://tribes.tribe.net...

We are four dimensional beings. We do see the same as we do. Your argument sounds extremely strange now.

The Earth is a 3D object. In 4D space it is not a weird 4D cylinder - it is an object missing one of its dimensions. If we view it in 4D, we see it in 3D, just like we see 2D in 3D as 2D, if that makes any sense.

I think my running of an "even if the Earth were 4D" argument probably confused you (:
