Quote:Your logic is flawed; how do you know the universe certainly can hold a line?
And even if the universe can hold lines, the logic is still flawed. programwizard makes assumptions on the topology of the universe.
Consider the surface of a sphere (imagine a worm on an apple). Would you say it's infinite ? Definitively not. But it can hold a line between any of its two points, and appears inifinite to the worm. Same story with the surface of a tore, which is very different from the sphere.
Now, these are 2D examples, and our space appears to be 3D. But nothing prevents it to work in the same way (altough it's hard to mentally picture).
