Forget dark whatever, we're barely starting to find the visible matter.

The heavens may be strewn with stars, galaxies, and nebulae, but the fact is astronomers don't know precisely where most of the ordinary matter in the universe is hiding. A new x-ray observation could help untangle that mystery: Astronomers have located a filament of hot gas stretching all the way from one cluster of galaxies to another. The filament is thought to be one thread in a vast web containing the missing ordinary matter, and, if confirmed, it could give scientists a better idea of where the rest of the stuff is lurking.​

This study of cosmology is some amazing stuff. I think it may be presumptuous to think that "C" is or has been isotropic forever. Given the fact that time is compressible or expandable in relation to matter and gravity the change in "C" over time could be described by a fairly complex differential equation. The same thing goes for the missing mass or dark matter. It may not be visible yet because it's illumination state has not reached us yet.

God Bless

..... not to mention the grey matter ..... rimshot, please



One straight line deserves another:

You do realize that the plasma cosmologists have a lot to say about all that hot gas ....

 

[shernren]

... namely, that it never needed to be created, can subsist forever on its own, and will continue forever - because if the Big Bang is bogus who needs a beginning for the universe or anything outside it?

You blasted a blog simply for calling an experiment "creating a universe". You're strangely willing to tolerate far more blasphemy from those whom you find scientifically convenient.

Get a sense of humor.

"Hot gas"? As in straight line? As in your opportunity to poke fun at plasma cosmology?

 

[shernren]

Meh. I saw it but I thought ... "That can't be it! It's too obvious! It makes too much sense!"

Another episode in the sordid saga of missing normal matter.

http://sciencenow.sciencemag.org/cgi/content/full/2009/220/1?etoc

Even most of the ordinary matter is still missing. About half of ordinary matter has formed stars and is clearly visible. Most of the rest, which floats between galaxies, is ionized gas that is hard to see. Since 2000, astronomers have caught patches of this "warm-hot intergalactic medium" (WHIM) by, for example, spotting clouds of oxygen VI--oxygen stripped of five of its eight electrons--as they absorb the ultraviolet wavelengths in the light from quasars far behind them (ScienceNOW, 25 November 2002). But most WHIM is still unaccounted for, in large measure because the ions that trace the hotter stuff, such as oxygen VII, absorb x-rays. Because the oxygen VII is so diffuse, it is extremely difficult to detect whether x-rays have been absorbed by the gas.

Now David Buote, an astrophysicist at the University of California, Irvine, and an international team report the detection of x-rays absorbed by such missing ordinary matter. Using NASA's Chandra telescope and the European Space Agency's XMM-Newton, the team spotted this gas along a portion of the Sculptor Wall, part of a large assemblage of galaxies some 400 million light-years away. Oxygen VII between the galaxies absorbed x-rays coming from an energetic galaxy behind the Sculptor Wall. Buote gives their detection a 99.7% chance of being correct.

Exactly what I have been trying to tell you for years. When it comes to remote cosmology we know very little and the evidence we have is rather limited.

We cannot see 96% of what is out there and the bits we have observed because they are currently visible in the electromagnmetic spectrum have probably been misobserved.

Game set and match against anybody whose been spouting off theories of remote cosmology with anything like certainty based on scientific observations alone!!!!

 

[shernren]

The fact that we're slowly and actually finding the missing bits - doesn't that say quite a bit about what science can actually do?

 

[MiserableSinner]

We only "know" about this "missing" matter because the Big Bang theory thinks it should be there.

I get nervous when a theory causes us to suddenly "realize" that our data set is horrifyingly incomplete. Evolution had an overhaul called punctuated equilibrium. Perhaps the Big Bang needs one, too.

 

[shernren]

Hmm. Just yesterday in my Nuclear and Particle Physics class our lecturer was rehashing the history of particle physics. She got up to the Standard Model in about 1975 and then said:

"The rest of particle physics, up to now, has been looking for problems and flaws in the Standard Model. Unfortunately we haven't really seen anything that can knock it down just yet. I say unfortunately because if we prove the Standard Model right - and that's likely to be declared if the LHC finds the Higgs Boson - then we can all pack up and go home. And we don't want that."

 

[chaoschristian]

Evolution had an overhaul called punctuated equilibrium.

If you think punctuated equilibrium was an overhaul of evolutionary theory, then you don't understand what Stephen Gould wrote.

 

[MiserableSinner]

Whatever floats your boat.

 

[chaoschristian]

Whatever floats your boat.

That's rather dismissive. Have you read Gould?

 

[MiserableSinner]

Isn't it? Gould helped us realize that the fossil record is substantively complete. The Big Bang helped us realize that our picture of the universe is substantively incomplete. So to answer your question: Yes.

 

[chaoschristian]

So I see you haven't.
