There are two good questions to ask about this, at least.
1. Why would photons lose energy and nothing else lose energy
over
the
course of great distance and time?

So I ask you: "What else is there, besides photons, to lose energy
over the course of great distance and time?"
Out there, there is only photons, space and time. Nothing else.
Your "nothing else" is false, because there's "nothing else" there.

Things to investigate:
- nebulas
- asteroids
- solar wind
- interstellar molecules (some of them quite complex)
- neutrinos

All those are matter.
All those belong to the "source" of the question.

You said there's nothing but photons in interstellar
space. This contradicts you.

Yes it does.

Let's review.

You believe in tired light, that light loses energy as it
propagates long distances.

PD asks, what makes light lose energy while other
stuff doesn't lose energy going long distances?

You said there is no other stuff. Now you acknowledge
there is other stuff.

So the question is back to you: what makes light get
tired, but not other stuff such as neutrinos?

Easy question.

Well, let's see what is light:
- is a frequency
- travels at c
- carries momentum
- momentum depends on c and frequency

Experimental facts:
- light loses momentum

This is not an "experimental fact". The experimental fact
is that light from farther away has, in general, lower
frequency (and the photons have less energy and
less momentum).

Your THEORY is that the momentum changed
enroute. That change is not an "experimental fact".

The competing theory (Big Bang theory) is that
the photons from the distant objects had less
momentum/energy relative to us, because they
were emitted from an object moving away from us.

As you do not have observations of the same
radiation from intermediate points or from the origin,
you can not claim the initial or intermediate momentum
as "experimental fact".

Momentum sounds like inertia and inertia sounds
like mass.

I think you're saying that "momentum" implies "mass"
which of course is an antique viewpoint no longer recognized
to be true, since sometime in the 19th century.


So, why shouldn't light momentum change, since
neutrinos momentum had changed too?

What evidence do you have that the neutrinos' momentum
changed?
