Fran - The article is behind a paywall, so it is not clear how the authors interpret the gas as being molecular (other than it being charge neutral).
One way to look at this event, the way that Randell Mills would possibly explain it (or his supporters) is that the “molecular gas” which looks like hydrogen is a good fit for his definition of “dark matter” … which is protons bound by electrons at the minimum radius– the deep Dirac level. The Meulenberg paper has been mentioned before: http://www.borderlands.de/Links/DDLemission7.pdf Dark matter can be equated, in this viewpoint, with “dense hydrogen,” DDL, virtual neutrons, “Rydberg hydrogen” or IRH (inverted Rydberg hydrogen) all of which names and concepts are pushing towards a species in which stability is achieved in a very dense state, trillions of time denser than “normal” molecular hydrogen but less dense than a neutron star. Of course, in terms of actual mass across the Universe, this dark matter species is probably “normal” and what we have on earth in the form of H2 is probably an extremely rare form of molecular hydrogen :-) From: Roarty, Francis X Supermassive black hole blows molecular gas out of a galaxy at one million kilometers per hour http://www.sciencedaily.com/releases/2014/07/140707121413.htm [snip] Professor Clive Tadhunter, from the University's Department of Physics and Astronomy, said: "Much of the gas in the outflows is in the form of molecular hydrogen, which is fragile in the sense that it is destroyed at relatively low energies. It is extraordinary that the molecular gas can survive being accelerated by jets of electrons moving at close to the speed of light." [/snip]
