I'm really glad you asked. The exact quote:Nereid wrote:I checked Morris et al. (2006), but could not find those words; may I ask what you are quoting?(davesmith_au) wrote:Furthermore, Morris is quoted as saying: “You can regard these magnetic field lines as akin to a taut rubber band, ... If you twist one end, the twist will travel up the rubber band.” Does this make him incompetent too? (The same caveat as I previously used applies to this statement).
comes from BOTH the UniverseToday piece, AND the UCLA press-release. In fact, Fraser's only original input to the article on UT is the first paragraph! The rest is copied, word for word (as far as I could tell) from the press-release. So Fraser himself has added exactly one paragraph of original information (17 paragraphs in the UCLA release, 18 in UT), yet the story is listed as "by Fraser Cain" not "posted by Fraser Cain" which would be more accurate, under the circumstances don't you think?“You can regard these magnetic field lines as akin to a taut rubber band,” Morris added. “If you twist one end, the twist will travel up the rubber band.”
I not only checked Morris et al. (2006) but have read through it and understand the bulk of it. Of course rubber bands are not mentioned in the paper, because Fraser got his info from a PRESS RELEASE! Which, incidentally, includes a number of quotes from Morris, including the one I referenced.

Go take another peek at the Universe Today writeup on the DHN. It likewise doesn't say "it is at least 20 arcminutes (50 parsecs) in length, extending between galactic coordinates l = 0.08, b = 0.5 and l = 0.02, b = 0.80". Does this make Fraser Cain incompetent (or at least, unscientific) too?
The UCLA News Release contains the following: "The research is published March 16 in the journal Nature", "Morris has argued for many years that the magnetic field at the galactic center is extremely strong; the research published in Nature strongly supports that view", and "Co-authors on the Nature paper are Keven Uchida, a former UCLA graduate student and former member of Cornell University's Center for Radiophysics and Space Research; and Tuan Do, a UCLA astronomy graduate student."
So no, it doesn't; Fraser Cain cites his sources, so his story can be checked against the only thing which counts as physics, papers published in relevant, peer-reviewed journals.
Fraser's source was a UCLA PRESS RELEASE (you said this yourself!) which certainly doesn't have any content from the published relevant peer-reviewed journal paper!
There is a huge difference between what comes out in press releases and what is in the papers supposedly supporting said press releases, which is kind of the whole point of this discussion. TPODs are NOT written in response to some peer-reviewed published paper in a journal, but in response (often, but by no means always) to press releases given out by reputedly scientific organizations.
Your view "the only thing which counts as physics, [is] papers published in relvant, peer-reviewed journals" is the real problem here with many of your discussions on these forums. I am not discounting the value of such papers, but they are NOT where most of the general public get the bulk of their science information from. They get it from (often sensationalist) press releases. That unless something appears in a published, relevant peer-reviewed journal is the only thing which "counts" as physics is a somewhat myopic view to hold, in my opinion, and is not conducive to productive scientific discourse.
Another trait conducive to productive scientific discourse (and which has some sway in the integrity stakes) is the ability to admit "I was wrong"...
Cheers, Dave.
PS - Considering the hullabaloo on another thread regarding credits for images, I find it ironic that on this particular story, Fraser listed the image credit as "NASA/UCLA" whereas the press release he cites as his original source states it as "NASA/JPL_Caltech/UCLA". A bit sloppy, don't you think?
