Ok, so what I'm to take from this is that space (that is: physical area devoid of matter and energy) isn't devoid of the laws of nature/physics/etc...therefore you don't consider it empty?
And it's as these laws are expanding with the universe, it is "conquering" space with no laws, and making it space with laws?
Actually, space is anything but empty. Almost all of space has energy, often in the form of light, traveling through it. Normal matter composes only a small portion of the universes matter/energy total. Additionally, even in a vacuum, there exists "virtual particles", or particles that spontanously generate and decay in time periods so short they can't be directly measured. However, the experitmental evidence, such as the casmir effect, support this model. Space isn't expanding into "other space", its just expanding. Ie draw a small circle on a balloon, and blow it up. The circle gets bigger. Its the same space expanding.
As for the physical rules that the universe opperates by, it may well be a simple function of space. However, that is personal conjecture. I am not sure if there is a theoretical approach to this question, or if it is currently outside scientific perview.
