Expanding Universe

Can someone explain how astronomers have concluded that the expansion of the
universe is accelerating.

Supposedly the further distant stars are offering a greater redshift,
and otherwise supposedly nothing that's way out there is in blueshift.

However, there's certainly a great deal of dark matter in between that
could be affecting those subjective notions, or perhaps the stars
furthest away are simply more massive and thus causing their very own
gravity redshift.

NGC 1569 is in blueshift at -104 km/s.

M31/Andromeda is in blueshift at -300 km/s

"There are about 100 known galaxies with blueshifts out of the
billions of galaxies in the observable universe."

"Supposedly"? After the starts were measured by hundreds or thousands of
astronomers, you claim it's "supposedly"?

Precise measurements of redshift are "subjective notions"?

Probably not. If they were more massive, they'd be hotter and brighter.
And that difference would suggest some change in the evolution of stars.

For some reason your subjective notions are better than those from
people who actually study astronomy.

They're also pretty close.

Yes, at least until some one objectively nails Dark Matter and
possibly Dark Energy.

I've never claimed my subjective notions were the one and only word of
God, much less of any Republican Zionist/Nazi God.

As far as we know with any objective certainty, as of 10 billion years
ago the expanding universe came to a bloody halt, or even having long
before revered itself. The best science data we've got about our
universe is clearly outdated by 13.5 billion years, if not by a whole
lot more. In other words, how much fudge factor would you like?

Redeye My Concave & Convex theory gives the answer why space between
the galaxies is expanding at an accelerating rate. We see this very
clearly viewing the red shifting of light. TreBert

Models attempting to explain accelerating
expansion include some form of dark energy:
cosmological constant, quintessence, or phantom
energy, with the latest WMAP data favoring the
cosmological constant...

Does the color change, BEERTbrain? lmao!

Nope.

Cactus saul If its possible to get this through your low wit brain I
will tell you once again. The DOPPLER SHIFT of the spectral lines
towards the RED end of the spectrum show to us that galaxies are moving
away from us. That the further away the galaxy is from us the greater
its REDSHIFT(that is the faster it was moving away) This relationship
tells us that the universe is expanding and that means it had a definite
beginning at a certain moment in time. Well Saul I could go on and
on,but please try to let this information get into your thick scull.

What about dark matter (carbon black diamond) that's not expanding?

Most if not all of dark matter(carbon black diamond) is not forever
expanding and speeding up, unless there's an area or cosmic realm of
the electrostatic force of repulsion taking place.
