My case against Creationism and Infinite regression

[robvalue]

I lurv infinite regressions . . .

This is actually extremely relevant to a post I made on another thread, talking about whether there is a fundamental, irreducible building block:

Well, I couldn't possibly say. As far as I know quarks are the smallest component, although I think it's the case that ultimately everything exists as a probability field, as per quantum mechanics. When you get down to the real small parts, things stop being so clear cut as just "stuff" and start becoming increasingly abstract and weird. I don't have a great grasp of QM but we have plenty of people here who do. There's also wave/particle duality and such.

Can you keep on going, indefinitely? Maybe you can. Maybe reality is like a fractal. Again, I don't think you can rule this out. You'd be assuming some sort of "end point", without ever being able to test that it really is an end point and not just the limitations of your technique.
