Throwing the baby out with the bathwater[edit]

We need to be more careful when discussing molecular clouds and star formation. Ten or twenty years ago this stuff was largely modeled in terms of gravity and gas pressure. Today, electrical, magnetic, and Magnetohydrodynamics phenomena are seen as a major force in dense core collapse and star formation. For example, there are dense cores thousands of times as massive as could be explained by gravity and gas pressure alone. In a prestellar nebula, magnetic forces hinder collapse, but plasma jets shed huge amounts of angular momentum that would otherwise cause the prestellar nebula to break up. Let's not confuse Alfvén with contemporary astrophysics. For more info, go to Google Scholar and search on either "molecular cloud" or "star formation" plus "MHD" and you'll see what I mean.

Page Protection[edit]

I've just found links between plasma cosmology and plasma scaling, which are not valid because the topics discussed are quite unrelated. It seems these have been deliberately linked probably as vandalism to either mislead or support plasma cosmology. I found it as the scaling factors stated are different under different circumstance, but in plasma cosmology the scale is presumably linear. The addition (and the plasma scaling edit/article was made by Iantresman here [1] and who has been a previous editor of plasma cosmology related articles.

I need time to see where and how these edits have been applied and fix these edits on both pages.

I also want to remove the scaling image. I.e.

"Image:Cosmic-triple-jump.png|thumb|200px|Hannes Alfvén suggested that scaling laboratory results can be extrapolate up to the scale of the universe. A scaling jump by a factor 109 was required to extrapolate to the magnetosphere, a second jump to extrapolate to galactic conditions, and a third jump to extrapolate to the Hubble distance.[1]"

I would then link the reference to...

"Some theoretical concepts about plasma cosmology originated with Hannes Alfvén[1], who tentatively proposed the use of plasma scaling to extrapolate the results of laboratory experiments and plasma physics observations and scale them over many orders-of-magnitude up to the largest observable objects in the universe (See box[1].)"

Note: I have removed the offending material from plasma scaling

@DRAGON BOOSTER: Please explain. Thanks. Arianewiki1 (talk) 11:33, 2 February 2017 (UTC)
i assume you'll defend and take responsibility for the attack that is just about to start? Arianewiki1 (talk) 11:36, 2 February 2017 (UTC)
Not sure what you mean, as this article hasn't been protected since September 2014. Doug Weller talk 12:05, 2 February 2017 (UTC)
@Arianewiki1: I just removed the edit request template because the article is not semi protected, that is all. I assume you want it to be protected, then you can make a request here. regards, DRAGON BOOSTER 13:53, 2 February 2017 (UTC)
@DRAGON BOOSTER:. Oh, my mistake. I posted it in the wrong place. Thanks for pointing me in the right direction. Have a good one... Arianewiki1 (talk) 14:21, 2 February 2017 (UTC)
