First of all, the Universe is the Universe, there's nothing hypothetical about its existence. Second of all, there's nothing chaotic (mindless) about the way it functions. Can a computer function wihtout a mind or central processor? No. Why? Because it's all about timing and accuracy. Indeed, it can run thousands of processes at once which, may appear to be at random or chaotic, and yet that's simply not the case. The same thing applies to all the timing and accuracy which is necessary to provide a "stable" Universe. There's nothing about the Universe which does not behave according to what it's been "told" what to do ... i.e., through the "collective process" which holds everything together.
