Comment addressed to Vikram Arora:
I like much of your infinite universe theory. You certainly are differential to the Big Bang theorists, who have proposed a direct contradiction of Infinite Universe Theory. All their calculations assume that the galactic redshift proves that the universe is expanding. This is in accord with Einstein's view that space is empty and that nothing should happen to the light that travels through it. Many of us do not believe that space is empty, or that time is a dimension like Einstein assumed. I consider time to be motion, which is not matter, but what matter does. The microwave background proves that space is not empty, but that it contains matter in motion (the definition of temperature). Empty space would have a temperature of 0 degrees K, not the 2.7 degrees K that is observed. Recent measurements (and some of the old ones) indicate that there is an ether that is the medium for transmitting light motion (see p. 203 in “The Scientific Worldview”). Like all wave motion, light loses energy over distance, becoming red shifted and eventually absorbed. So the infinite universe is 3-dimensional and eternal, as you say.
