Hi all. I'm rather a novice in the realm of physics, aside from a class in high-school and my own independent interest. I often wonder if matter is infinitely divisible. What if it's possible to divide quarks, gluons, etc, we just don't have the methods? Does anyone have input on this idea? Is there some law which would prescribe the infinite divisibility of matter? Or, at a certain point, does matter simply become energy if we further divide it? Thanks!
