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).

But that's exactly what I've been saying for so long.
And now you add even more : "energy too".
Yes, that's exactly what I've been saying for a long
time in this thread.
The experimental fact is that light from farther away
has (depending on distance) lower frequency, so that
the photons have less energy and less momentum.


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

My theory is that stars are made of hydrogen that
burns in nuclear fusion processes. They emite light
for which we EXACTLY know the spectrum.
Nevertheless, depending on distance that light has
to travel to reach the earth, the frequency of such
light that we have to assume has a given frequency
spectrum, arrives with all frequencis equally shift
to the red (lower frequencies).

The above is not a theory. It's a 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.

Now we have a trouble.
That's not the Big Bang theory.



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".

Nor your theory can claim many things.

Why close stars burning hydrogen emite a given
spectrum and the more distant stars, burning the
same hydrogen have the spectrum shifted to the red?

It's not an "experimental fact", its just "a fact" that the
laws of physics must be the same everywhere (to iFoR).

So, hydrogen burns close, like it should burn at distance.


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.

Sortof, yes.
What I know for sure is that light loses momentum,
because that's an irrefutable fact - REDSHIFT.


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

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

They arrive late, remember.
The smaller the mass the higher the frequency.
(any mass-spring system obeys such law)

As a specific example, when supernova 1987A was observed
optically, physicists realized there should have been a
corresponding burst of relativistic neutrinos that arrived
slightly behind the light. They went through the data of
the neutrino detectors around the world and found the
expected burst.

What makes you think that neutrinos had been shoot of
exactly at the same frequency and speed has they arrive
here on earth.
Neutrinos have to be effected by the fabric of space-time,
or else expansion, or else the fact that the actual source
is actually receding from us. Pick your choice.
