Dear Professor Kozlowski,
I found your essay fascinating, and I only have one problem with it. The real Universe is unique, once. Everything in the real Universe is unique,once.
Based only on my observation, I have concluded that all of the stars, all of the planets, all of the asteroids, all of the comets, all of the meteors, all of the specks of astral dust and all real things have one and only one thing in common. Each real thing has a material surface and an attached material sub-surface. All material surfaces must travel at the constant "speed" of light. All material sub-surfaces must travel at an inconsistent "speed" that is less than the "speed" of light. It would be physically impossible for light to move as it does not have a surface or a sub-surface. Abstract theory cannot ever have unification. Only reality is unified because there is only one reality. The interferometer that Michelson and Morley used in their solar wind experiment had a surface. The room in which the experiment was conducted had a surface. Michelson and Morley had surfaces. All surfaces travel at the "speed" of light. The only thing that did not have a surface was the light that the pair used. No wonder it performed unusually.
We know that the earth is habitable. Speculating on whether any other planet in the real Universe is habitable is utterly futile.
With the utmost respect,
Joe Fisher
