Please see my replies to others on this topic.
Clearly, Schroeder incorporates a lot of theology in his books, which hold little interest for me, except as pertains to this concept of light and time.
I'm trying to determine if scientific laws, theories, or principles are violated by this kind of thinking. If I were to pursue development of a thought experiment (a la Einstein's methodology for special relativity), do I need to address this possibility? Or is it clear from other scientific observations that a clock riding on an hypothetical bubble-membrane at the very edge of the expanding universe would show the same time as one sitting at the center of that same universe?
I've heard that galaxies are moving "faster" at the edge of the universe than near the center. Some have proposed this to be analogous to planetary orbits (gravitation lower at outer regions), but could it also be that as we look out, we are "seeing" light emitted at an earlier time, when the universe was "smaller" and expanding more rapidly than today? If so, then that hypothetical clock at the outer fringe would seem to me (according to relativity) to be ticking "slower" than my own clock. But then, I don't really know how far I actually am from the fringe, do I? Is it permissable for me to use the difference in ticking to estimate difference in distance from the "center"? Sorry, that last question will take us off topic.
In any case, thanks for taking my questions seriously. I don't know too much (isn't it obvious?), but am eager to learn.
