<br />GD, there's no need of a graviton in GR, ...

I think you meant in the standard model. General Relativity needs the graviton so that mass is conserved.

It's a hot day and you are ouside with a toddler. The toddler will get all fractious. That's becausethe toddler's volume follows a cube rule, and the toddler's surface area, a square rule. The poor kid has more bother dumping heat than you do.

The same goes for galaxies, a group of galaxies is in much better thermodynamic shape than a single one.

But I must point out again, teh entropy curve latlines out at either end. Galaxies don't radiate themselves away in short timespans. Cohesive forces stop this from happening.

A hundred galaxies that merge into one mega galaxy is what I am talking about.
This mega galaxy is in worst thermodynamic shape than a single one.
The clusters of galaxies are in the process of merging!
Cohesive forces cannot stop this from happening.
The greater the mass, the greater the disorder (just compare the Earth with the Sun - 1 million Earth-mass).

Although this theory is not a pleasant one, I think it is too close from being true to disregard.

You might want to have a look at this www.cosmiclight.com/imagegalleries/gcollisions.htm

A goggle search for the coma berenices galaxy cluster might help as well. There's about 30,000 galaxies in the group and the average distance between them is only 300,000 l.y's.

I did find this partial article at the new scientist site. www.newscientist.com/article/mg14219262....ough-the-heart-.html

Thanks for the links. I found some more on galaxy clusters. This article mentions the 100 million degree gas cloud surrounding a 1000 galaxy cluster:

Such clusters have NO life form within them.

I rest my case.

The coma galaxy cluster actually contains 30, 000 plus galaxies. The article is just talking about the 1000 elepticals in the cluster.

GD, you can't rest your case, just when it gets interesting[8D] I read the article and I have to say that the guy gets needlessly complicated when he tries to give an explanation of the cooler clouds associated with galaxy jets. Snowballs in a furnace he calls them.

A galaxy, or a cluster of galaxies, will have a halo of gas round it. At the gas boundary the conditions are such that we can have gas atoms ingest their electrons. This produces gamma rays. I would argue that the gamma ray flux could be the same as that for an isolated galaxy, or less.

Don't confuse temperature with heat. Stick a lump of steel onto a grinding wheel, the sparks that hit your hands are at about 1600C but the heat content is very low.

Life could, and probably does, exist in the coma cluster. I wonder what an astronomer there would make of the universe[]

To add to this, I went to see if anyone else was thinking of complex universes. I found this abstract on galaxies prola.aps.org/abstract/PRE/v56/i4/p4451_1 This differs from the idea of a complex universe having a faster than light graviton, in that the guy is looking at a galaxy as a viscoelastic and the velocities for phase transition are low but what he says is of relevence. On complex universes, Sir Roger Penrose would be the main man. I actually found an e mail address for him a week ago but he hasn't got back to me. It might be that the address is pretty dormant and he rarely checks it.
