On 13 March 2006, this article was massively expanded by 81.76.3.42 (talk · contribs). The expanded version can be viewed via this link. I'm concerned about several aspects of it:

• The narrative tone is completely inappropriate. It reads like an essay or press release, not an encyclopedia article, and fixing this would require another massive rewrite.
• All of this material was added over about 15 minutes. Many paragraphs also look like they've been cut off at the end. This suggests that the material might have been cut-and-pasted from somewhere. The fact that nothing in the added material is wiki-linked would be consistent with cut-and-pasting, or could just be the result of inexperience.
• Many of the conjectures put forward are questionable. Most notable is the speculation that Nemesis, a hypothetical companion star to the Sun, was formed as a result of a polar jet emitted during the Sun's formation.

There's probably quite a bit of material worth folding back in, but it will take a lot of effort to properly source it and present it in an appropriate manner. --Christopher Thomas 08:49, 22 March 2006 (UTC)[reply]

• 'Polar Jet' is also a term used in atmospheric science, perhaps a link or disambiguation text can be added? 74.60.11.18 (talk) 08:26, 5 July 2008 (UTC)[reply]

• Oppose merge I don't think it should be merged, the polar jets in Herbig Haro objects are not relativistic. --Keflavich 00:38, 18 April 2006 (UTC)[reply]
• Oppose merge - they're not the same thing at all. Worldtraveller 18:52, 18 April 2006 (UTC)[reply]

The most obvious question left unanswered about polar jets is, what causes them? -- Beland 00:49, 21 April 2007 (UTC)[reply]

the current article reads: "whereas if it originates in the black hole it will likely be electron-positron in nature". This is confusing because jets can obviously only form on the 'outside' of the event horizon. 86.177.223.152 (talk) 22:07, 2 August 2011 (UTC)[reply]
