Re: Warning: Pet Peeve ahead.
OK. I'll acknowledge that the Speed Force may allow its users to operate under an altered set of physical laws by its nature. However, I'd like to point out that insufficiently understood science is indistinguishable from magic. Just try and prove beyond a shadow of doubt that the Speed Force isn't magic. (Seriously. The same laws of physics apply in all reference frames, including super speed, unless you start getting into quantum mechanics or string theory, which aren't really applicable here I don't think. The Phantom Zone, on the other hand, can be described as being another four-dimensional finite closed universe, as ours is sometimes theorized to be, parallel to the standard DCU and accessible only through fifth-dimensional space with the aid of certain machines. Unstable molecules probably involves quantum mechanics.) Nyah nyah nyah... ;P
