Probably a stupid question but..

This thread signifies whole obscurity of TR. Many of us use the “expansion of space” term but no one is able to explain what physical (measurable) parameter of (“empty!”) space is changing during the time. Yet, if we consider the Minkowski metrics (a priori the determined future) that does not meet the triangular inequality, the goulash is perfect :( But there is simple escape here: The Universe does not “expand” but it grows. It grows, condensates from the “Future” (phase) that surrounds it. The "Future" supplies to the Universe as the matter (Planck stem cells or elementary particles), as well the information (structure, ideas). The growing presence (the time of “now”) is a rather uncertain phase border between the determined (condensated) history and (uncaused yet) the Future :)

On earth Doppler shift is easily understood, because distances allow for a CPA. If one does not experience a CPA how can one know that either the blue or red is due to opening or closing, as there are many other things that can account for either color. Stars, themselves, emit various frequencies of light. Without a CPA how can one know that in fact the color is due to a shift. Shift is a term of relativity indicating deviation from a known value, static value, if you will. One would have to know the static value in order to positively identify either the red or blue as a shift. The great distances other stars are from earth, and their relative trajectories, preclude CPA, such that a 'static' reference cannot be understood so as to know if in fact the red or blue is due to the Doppler effect. How can the shift from a baseline ever be understood is in fact the baseline can never be understood?

The human mind cannot conceptualize fluidity without freezing it into a point.
To do so it must simplify/generalize what appears by placing it within conceptual boundaries, which remain ambiguous, and within which a unity of order can be created.

The Big Bang simply represents a conceptual point, in theory, to a singular, or to the absolute.
It is no event in space/time but an ongoing process which is receding beyond perception.

The event is not a some-thing occurring within a something, but it is a process the mind must simplify into a metaphor.

It represents the closest point to a static. Space being a projection of possibility, the closer one gets to the Big Bang event the less possibilities there are, given that the even represents a near-absolute order.

We might say that the particle, the singularity, the Big Bang is the secularization of the God concept.
