Thanks again to you all. Now I have some homework to do before proceeding with this line of inquiry.

Thanks...I turned off signatures in an attempt to eliminate their repetition. Guess I'll have to turn them back on.

Thanks, Marcus. I didn't see the link you referred to. Is that because of a setting I may have?

Right on! How would this curvature affect something like the Minkowski representation of an individual perspective? I've been inclined to think that negative spacetime curvature would be reflected in an outward flaring of the cone. However, as I mentioned elsewhere, this would seem to conflict...

Thank you very much. You've addressed the question I intended to ask regarding the curious coincidence between the observational limit imposed by the speed of light and what you refer to as "the interference effect by the CMB." Perhaps not surprisingly, I find the notion of fine tuning to be...

Thanks for your comments. Just to be sure we're on the same page, when I refer to an 'observational universe,' I mean the spacetime domain that is observable from a particular point in spacetime. For all practical purposes, such a point could be regarded as virtually identical for...

Cosmologists seem to refer interchangeably both to a big-bang origin just beyond the limit of present observation, and to an observational horizon where the rate of expansion of the universe exceeds the speed of light. The notion that looking out in space entails looking back in time gives...
