A long, hard look at distant galaxies

When ESA reported on a Hubble deep-field galaxy survey, they came within a whisker of stumbling over a connection which seems to largely evade modern astronomy:

The reheating, driven by the galaxies' ultraviolet starlight, transformed the gas between galaxies from a cold, dark hydrogen soup, to a hot, transparent plasma over only a few hundred million years.

OK, so if space is full of plasma, why not treat it as such?

Plasma is magnetically & electrically active, vastly different from the colder, gravity-driven cosmologies upheld of late.

So many features of galaxies — of our own solar system — make much more sense if interpreted as being formed relatively quickly by active plasma fields rather than by cold rocks rattling around loosely.

Comets are a classic example, radiating where they shouldn’t in unexpected ways. But it only starts there — so many planetary & lunar features yodel “plasma” that they almost defy counting.

It’s good to see the concept being at least hinted at in recent texts. Now let’s see it followed through a bit more.

I think you are seriously mis-representing the ESA here.

They found that in the early universe reheating occured.

This is very different to saying, in the present tense, that "space is full of plasma".

We stay, generally, in a "reheated" state.

Space is indeed riddled with plasma.

Not certain that the ESA rep intended to convey that meaning, but it works.

Major said...

Objects to not in general stay [re- or otherwise] heated, they radiate.

Do you have any evidence for the assertion that space is riddled with plasma.

Here is one interesting starting-point, and here is one of many others.

Sorry, was a bit lagged getting back to this.
