We know the laws of nature that God invented for our universe, we knw the "Constants" , now while the Big Bang could have theoretically pushed forth they creation in the beginning at a faster clip, no stars were eve formed for the first 400 million years, thus all light travels at a constant, "KNOWN SPEED" the speed of light.
No they haven't, all of the measurements are via only this Universe, of course, the only thing even seen out side of our universe was Quantum Fluctuations as they call it, I say that was God and His creation powers moving, of course. Time stops as you leave this Universe. The reason Gd has no need of being created is because he is not from this universe, all things of this universe must needs have been created.
