At risk of being considered a crackpot, I see serious flaws in the entire Big Bang Theory.

For one thing, the principle of falsification doesn’t apply to it. When prediction and observation don’t match, some massive force of nature is inserted, like dark energy, and accepted without question. How can that qualify as science? What if accountants just added a sum and called it dark money, any time the books don’t add up?

One of the very first patches applied was when they realized this expansion increases over distance, in equal proportion, in all directions, creating the effect that we appear as the center. So it was changed from an expansion in space, to an expansion of space, because “spacetime!” Which totally ignores the central reason for spacetime, as a physical explanation of the math of GR, that the speed of light is always measured as a Constant. Obviously if it’s being redshifted, it’s not constant to intergalactic space, because it’s taking longer to cross. If it was truly spacetime, the speed of the light would have to increase, as the space expanded, in order to remain constant.

Two metrics of space are being derived from the same intergalactic light. One based on the speed and one based on the spectrum. Given the speed is still being treated as the denominator, since the universe is supposedly expanding relative to it, as that is the reason for the redshift, the premise fails basic logic.

We are at the center of our point of view, so an optical explanation for redshift is the reasonable conclusion.

While single spectrum light does only shift due to recession, multi-spectrum light “packets” redshift over distance, as the higher spectrums dissipate faster than the lower ones, but that raises the question of whether individual photons travel billions of lightyears, or are we sampling a wave front?

Which then raises the even more sacrosanct issue of whether photons are indivisible units, or a quantization emergent with light interacting with matter….
