Kishock,

Thank you for the reply.

This seems to be the response I get, when I ask this question, that there are no arguments.

If I was to take a rubber band, with inch marks on it and stretched it, the marks would expand. Yet if I put that rubber band next to a ruler and stretched it, it would take more inches to measure it.

If it was truly relativistic spacetime, then the inch marks, the speed of light, would have to stretch with the space expanding. Then it would be constant.

So if the argument is that we can tell the space is expanding, because it takes light longer to cross and so it's redshifted, then the speed of light is not constant to the space.

What is the basis of the speed of light, if it's not space? Einstein said, space is what you measure with a ruler and the speed of light is certainly a ruler.

I've been raising this issue for several decades and when people don't have an argument, they mostly just drop the subject, because the assumption is obviously that I just don't know what I'm talking about.

I do think there are other possible explanations.

Here is an interesting paper, making the point that multispectrum light "packets" do redshift over distance, as the higher frequencies dissipate faster;

I added a space, so the whole paper doesn't download.

The issue this raises is that we would be observing a wave front, not individual photons, traveling billions of years. Which raises an even more thorny issue, as to whether photons are as irrducible as is assumed. Here is an interesting essay, arguing for a "loading" theory of light;

An issue I keep trying to raise in various different contexts, not just physics, is that as these mobile organisms, this sequential process of perception, by which we experience reality, is logically a requirement of navigation. So our experience of time is as the point of the present, moving past to future. Not to mention narrative based cultures.

Physics codifies it as measures of duration.

Yet change turns future to past. Tomorrow becomes yesterday, because the earth turns. Duration is the present, as the events come and go.

There is no literal dimension of time, because the past is consumed by the present, to inform and drive it. Causality and conservation of energy. Cause becomes effect.

Energy is "conserved," because it is the present, not some dimensionless point between past and future. It creates time, as well as temperature, pressure, color, sound. Time is frequency, events are amplitude.

Time is asymmetric because it is a measure of action and action is inertial. The earth only turns one direction. Entropy is second order effect and not what is being directly measured.

Different clocks can run at different rates simply because they are separate actions. Think metabolism.

So energy, as process, goes past to future, while the patterns generated go future to past. Think in terms of a wave; The energy drives it, as it passes through, while the fluctuations rise and fall, back to equilibrium.

In terms of a factory, the product goes start to finish, while the process of production goes the other way, consuming material and expelling product. As lives go birth to death, while live moves onto the next generation, shedding the old.

Consciousness also goes past to future, while perceptions, emotions and thoughts go future to past. Though it is the digestive, respiratory and circulatory systems processing the energy, feeding the flame, while the centeral nervous system sorts and orders the information, but that's getting off topic...

So, back to the issue of quanta. What if the information is not synonymous with the energy?

Quantum physics is all about the information that can be extracted, so it might raise some interesting possibilities.

For example, consider the excess gravitational effect, currently explained by dark matter. What if this relationship between energy and information is equal and the inward curvature, aka, gravity, starts with whatever information is created. Not simply where it starts to quantify, but where it starts to wave. Then any bending of the light isn't due to gravity, it is gravity.

Another, related thought; Is space three dimensional, or is that just a mapping device, like longitude, latitude and altitude?

If we remove all physical properties from space, it would still have the non-physical qualities of infinity and equilibrium. Infinity, because there is nothing to bound it and equilibrium is implicit in Special Relativity, as the frame with the fastest clock and longest ruler would be closest to the equilbrium of the vacuum, the unmoving void of absolute zero.

Which makes space the absolute and the infinite.

Then consider that what fills space is this energy and the information it manifests. The energy radiates out, toward infinity, while the form coalesces in, toward equilibrium. Both entropic. Thus galaxies.

The expansion of the light is balanced by the contraction of the form.

I could go on, but I don't want to try your patience too far and this is the basic idea.
