> There has been for years the understanding that IF a difference should arise between the nearby events that we can study well, and the distant events which appear dimly and vaguely, AND if we did not realize that such a difference existed, THEN we could reach incorrect conclusions.
Thank you for being so clear. I hope that your colleagues appreciate the rigor of your thinking.
I've actually become suspicious, as an educated layman, about the other underlying assumptions that may confuse our cosmological models. For example, as we look more closely at nearby stars, we're finding more and more planets and cold, intrastellar bodies that would be very, very difficuclt to observe because they're barely above the temperature of interstellar space, and not close enough to stars to reflect easily noticed light. So it raises a very interesting question of "how much matter is in a star's Ooort cloud", and "how much matter is in interstellar or intragalactic space? If a significant amount condensed into small solid bodies earlier in the history of the universe, they'd be quite difficult to take into effect or even notice except as gravitational effects affecting the overall mass of the universe and Big Bang expansion.
I'm beginning, personally, to suspect it as a mudane source of the "Dark Matter" which is showing up in our larger models of the universe. Have you seen anyone exploring the idea?
