I'm aware of your take locally, though clearly it seems that the density at galactic centers is gravitationally bound, almost certainly by one or more black holes which would seem to have been the seeds of galaxy formation (these must be quite old, the black holes having formed somewhat earlier in the history of the universe). And it should be gravitation which is the principle force in galactic clustering as well.

In miniature, at least, it seems to have been gravitation which grave rise to the formation of solar systems, so I'm just scaling it up.

That's certainly not to say however, that there isn't something else about which I'd scratch my head over.

What does seem quite odd though is recent observational evidence that the expansion of the universe is speeding up. If this is true, then the "dark energy" posited to account for it is very odd indeed.

As Hamlet said, "There are many things Horatio, that are not dreamt of in your philosophy." But I'm very curious and hope someday to know something ofthe "mind of God", particularly beyond this life if that's some aspsct of the way He has it figured.

Paris, France (SPX) May 07, 2008

ESA’s orbiting X-ray observatory XMM-Newton has been used by a team of international astronomers to uncover part of the missing matter . . .

Only about 5% of our universe is made of normal matter as we know it, consisting of protons and neutrons, or baryons, which along with electrons, form the building blocks of ordinary matter. The rest of our universe is composed of elusive dark matter (23%) and dark energy (72%).

Small as the percentage might be, half of the ordinary baryonic matter is unaccounted for. All the stars, galaxies and gas observable in the universe account for less than a half of all the baryons that should be around. . . .

We don’t even know half of what we know.
