There's contantly discussion about if the universe is infinite in size or not. I want to pose the question in another way: Is the number of galaxies infinite? My answer: No

Seriously, I don't have a well elaborate reasoning. I don't know if is even possible to know it. Just checking the opinion of the other members

one feature of the standard model, which he calls the "new cosmology", is spatial flatness. Assuming the underlying mathematical model is General Relativity, this means infinite space.

Futhermore you can't have the big bang and have an infinite universe. The big bang can only create a finite expanding universe.

MYTH? Now how absurd do you sound.
The big bang has been proven in more than 100 independant results. If you think that's a myth then tell me.
EVerytime you sit down in a chair do you fear falling right through the chair?? I didn't think so.

There is much data ignored by the mainstream that shows that it is incorrect. Ever heard of Halton Arp? He showed that the doppler interpretation of the red-shift is erroneous. Also it is well known that Planck radiation of every atom in the ubiquitous interstellar medium can and should emit a ambient radiation temperature of about 3K. see http://www.Newtonphysics.on.ca/COSMIC/Cosmic.html

A desperate appeal to the mob mentality.

well of course because infinity is not a number
How does a universe of infinite extent fit in with a Big Bungle cosmology?

For instance the old trickery of continuously steping 1/2 the distance towards an object, mathematically you will never reach it.

If stepping half of the way took one unit of time each time, you would be correct. However, I tend to cover 1 meter in half the time it takes me to cover 2 meters!
If I'm running at 1 meter per second and I want to cover a distance of 16 meters, the "old trickery" only tells me that I can't make it all the way to 16 meters in less than 16 seconds!
THe mathematics I used have nothing to do with time at all whatsoever.

Okay. What about gravitational redshift? And you do realize that expanding space would redshift waves passing through it, right?
It certainly isn't well known to me. I'm not inclined to accept that link as a reputable source due to its absurd treatment on Olber's paradox. If you opt to defend their article, consider also a more serious paradox related to Olber's paradox; we should be observing an infinite amount of EM energy if the universe was infinite and homogenous.
Wrong. The expansion of space would be imperceptible because we are embedded in space. The whole premise is ludicrous.
So, in other words you have no argument against it? It gives a simple explanation of the MBR and you cannot dispute it so you find something that you don't agree with and simply call it absurd.
Olber's Paradox does not take into account the fact that there is much intersteller gas and dust to absord and re-emit the radiation as 3K heat. Quite simple really.
Thus if you continuously take steps that "half" your distance to a certain point, you can never reach it.

It would manifest itself as a tendency for things to expand. Things like solar systems or atoms are self-correcting so their actual sizes would not increase as the universe expands (in a classical picture, it would manifest as a slight force), but something like an intergalactic light wave or cosmic microwave background radiation is not self-correcting, and the expansion of the wave causes redshifting.
Yes; which is why it's astonishing that the link you gave didn't bring that up.
It is curious why it's 3K nearly everywhere, instead of having a temperature gradient where gas steadily cools as it gets further and further away from galaxies. It's curious enough that in my mind it's a serious flaw in the model.
Did you read the article? What I said about the paradox is pretty much what it says as well.
On one hand BBT says to ignore the relative motions of galaxies at the edges of the visible Universe moving through space near light speed according to the doppler interpretation of red-shift. It says that these speeds do not violate relativity because it is only space itself that is expanding. On the other hand it can say that the expansion of space can cause physical relativistic effects within space seen in the red-shift. So which is it? Is the expansion of space exempt from the laws of physics within it or is it not?
The gas is EVERYWHERE and there are galaxies in every line of sight.

Yes I did, and I just re-read it. The article does not say that interstellar gas is blotting out the light from the infinite number of stars.
This is fairly confusing...
So? That's no reason why there shouldn't be temperature differentials.
The confusion is inherent in the absurdity of BBT.
The reason is that the matter emits Planck radiation at a specific frequency. Read the article. It tells you that.
From astronomical observations we observe that most matter in the universe is in the gas phase at 3 K. Stars of course are much hotter.

That expression stands outside the math of reality.
I reject the claim that infinite as a value of anything exists in reality.
Originally posted by Hurkyl It does not explain why most of the matter in the universe should be 3 K.
Also, you still have not explained why we observe only a finite amount of radiation and not infinite.

Subtillion, if plasma cosmology don't believe in neutron stars, what is the explanation that it gives to the pulsars?
