God And Infinity, Worlds Without Number Are Numbered To God?

[Rob Osborn]

Perhaps we can imagine in our little feeble minds that some actual infinity exists but the truth is that nowhere in the real world do we see infinity nore do we use any math that uses anything other than a finite limit to a number. There is nothing that is truly infinite that we work with. Yeah, Pi may go on forever but it is meaningless for us to use it as anything other than some finite limit. The truth is, if something is infinite, we can't know the ends of it nor can we do any math with infinite qualities. Thus- it is all in our minds.

Because calculus doesn't apply to the real world, right Rob? Oh, and since there is no way to count a negative number of things, those don't exist either--until you start thinking about vectors. Also, imaginary numbers aren't in the real world--until we start thinking about waves. Oh, and quaternions, there's no way they exist--well, until we start doing 3d graphics rotations on computers or look at what Hamilton and others did with physics.

Hey Rob, if we can only ever make an approximation to PI, how far off is the approximation If I measure the surface area of a single free-floating soap bubble divided by twice it's diameter (4 times the radius)? What does the average approach? Can God draw a perfect circle? A perfect square? If God can draw a perfect square, how far appart are opposite corners divided by how far appart adjacent corners are? Usually I would say the square root of 2, but that number just goes on forever so I guess it can't exist which means God can't draw perfect squares.

Since irrational numbers don't exist. I just wan't to know something about straight lines. How does it work in real life? Are all the in-between points which are irrational distances from each other somehow missing? Are any of the in-between rational points missing? Is there some kind of smallest length that exists, and what is it? The Planck length? If so, then what about trying to build a perfect square? is it possible? What about the distance between opposite corners?
