Just read the thread about string theory and infinity. Interesting stuff, and I've read a book you might want to check out. It's called Zero: Biography of a Dangerous Idea. It gets into some basic theories of infinity, black holes, the end of the universe, etc, etc. A very easy read, understandable to my 2-courses-of-calculus mind. Includes a couple interesting proofs too, like the proof that all the rational numbers (you know, 1/2, 1/4, etc) take up exacly zero space on the number line. An infinite number of numbers, and you would still have a 0 percent chance of hitting one if you threw a dart at the number line.

In fact I think I might take some more math and physics because of it. Much more interesting when you know where you're eventually headed.

I don't think the concept of a "point" on a line not having any dimension is hard to grasp, though. It's not an object, but a concept. Isn't a line an infinite set of points, and a point has no dimension?

What does that last line mean?
