We are accelerating compared to Spacetime
Our space is shrinking compared to expansion.
Gravity in our galaxy makes our space smaller, so
light seems to have longer wavelengths when it
arrives from places that are expanding,
relatively speaking.

Such nonsense, it is not even wrong.

if you notice something expanding, are you shrinking ?

If you are expanding, are other things shrinking ?

If you are not glowing, are you a dim bulb ?

If gravity is diminishing, and your weight stays the same, you are
expanding.

What if everything expanded equally/ Could you tell?
Yes you can! All the sausages in the meat shop would fall down!

those pesky proportionalities revile the truth every time

Greetings Serglo,
To find out if the observed red shift is due partly to our local
shrinkage, a new experiment is proposed. Make wavelength measurements
from a position in intergalactic space. Then the influence of
gravity in our galaxy will not be a factor. Any dark matter in the
test zone can be disregarded.

No, it is not. That is merely your fantasy.

That is the case even with universal expansion, i.e. here, too.

Your assumption is superfluous.

It is not. The cosmological redshift (*one* word) is consistent with
uniform expansion.

To find out whether our local space (how far do you think that extends?)
is "shrinking", you just have to look at the redshifts of objects that
are within that region defined by you. If there is consistent blueshift,
increasing as distance from us decreases, you won.

Of course, you are merely arguing from your own ignorance. There is no
consistent and increasing blueshift within a defined radius of observation.

Word salad.

Accelerations, like everything else, happen *in* spacetime.

Acceleration is a rate of change of velocity.

“Acceleration is a rate of change of velocity. ”
Yes, and all stars travel similarly around galaxies, but their velocity is not constant. They sometimes slow down and other times speed up. We may be going at a faster rate right now in our galactic trip.

If you meant “all stars of galaxy travel similarly around the galactic
center”, then you have to realize that there are not *only* spiral galaxies.
Post by john

The velocity of stars of a spiral galaxy is approximately constant at the
same distance from the galactic center. This is why one can produce
rotation curves, and finds that, surprisingly, the rotation curves of spiral
galaxies are peculiar; as if there were much more mass than the
electromagnetically interacting, baryonic matter. This is considered as one
piece of evidence for Dark Matter.

There are only gravity orbital curves.
Galactic stars are in orbit... they have no way to rotate...
around by no axis.

You have that exactly backwards.
The discovery of the rotation curves precipitated a wild scramble to save current gravity theory.
Dark Matter is the potential Saviour, but It hasn’t quite been found yet.

Not at all. You have no clue.

Utter nonsense.
but It hasn’t quite been found yet.
It has not been *detected*, i.e. observed *directly*, yet. Its effects can
be seen all over the place, though, from galactic rotation curves (which
would be Keplerian if there were no dark matter¹) to gravitational lensing
to universal expansion (which would be much faster if there were not dark
matter) to universal curvature (which would be greater if there were not
dark matter).

Light accelerates.
Our accelerations are only practical.
Space time expands in balance.
