I'm another of those with problems accepting the logic of the Big Bang.

For one thing, it can't be falsified, as whenever there is a gap between prediction and observation, some new force of nature is presumed.

Before Inflation, Dark Matter and Dark Energy, the original patch was when they realized that as redshift increases proportionally to distance in all directions, it makes us appear to be at the center of this expansion. So it was changed from an expansion in space, to an expansion of space, because "spacetime!"

Which ignores the central premise of Relativity. That the speed of light is constant to all frames. If the light is being redshifted, intergalactic light is not constant to intergalactic space. Two metrics are being derived from the same light. One based on its speed and the other based on its spectrum.

For one thing, the Doppler effect doesn't mean space is expanding, but that there is increasing distance between the source and the receiver. The train moving away doesn't stretch the train tracks, only increase the distance. Similarly this supposed expansion is not increasing the speed of light. The lightyears are not stretched. There are presumably more lightyears. So the speed of light is still being used as the denominator, against which this expansion is presumed to occur. As Einstein said, space is what you measure with a ruler and the ruler is still the speed of light, even according to this theory.

We are at the center of our point of view, so an optical effect would be the obvious solution and it has been observed that multispectrum light "packets" do redshift over distance, as the higher frequencies dissipate faster, but that would mean we are sampling a wave front, not observing individual photons traveling billions of years. Which raises even more problematic issues for quantum theory, than just a patchwork cosmology.
