I agree with you that God is not bound by any of our physical laws, space/time, dimensions, geometery, origins, etc. In fact, my "theme" on these threads has always been that time is part of the creation and not something in which the Creator exists.
We cannot measure Him by any means in the physical realm. That is why - in the physical realm, at the moment of origin - He appears to us as the Hebrew word Ayn Sof describes - infinite and null.
