Some clarifications: Alfvén did develop some pretty interesting ideas on 'plasma cosmology', and my comments about pseudoscience (etc) are not directed at the good work he did; the comments are directed at folk such as Thornhill and Scott (and many, but not all, the links on the page katlpablo cited are to websites with crackpot material) ... and Velikovsky.
The EU/ES crowd try very hard to shine with the reflected glory of Alfvén, but if you take the time to read their websites, you will see how selective their choices are. If anyone is interested, there is a very lengthy thread on the Universe Today website (under Alternative Theories) where the claims of folk like Thornhill and Scott are challenged.
One of the most interesting folk is Peratt (Alfvén died in 1995, and I'm not sure how active a researcher he was in his later years) - some of his papers seem pretty good, but he also has some very odd views. He seems to have done most of his work at one of the US weapons-related labs, so when you read his papers on astrophysics, you get a feeling that he has missed many good opportunities to make his case (e.g. he seems to concentrate more on images, and is mute on spectra, yet it is the spectra which would much more readily make - or break - his case!).
My intention was to direct the original creator of this thread to an an introductory site and an "authority" in the ideas he is asking about. I offer the forum an alternate view of what other posters understand belongs not to real science.
And it's just here that I have a problem. If one wants to read up on Alfvén, then please give a link to a reputable site where you can get hold of his publications. IMHO, a "Catastrophism" website is exactly NOT where you would go to do that.
I believe a final answer has not been reached yet about the validity or worth of Alfvén's teories or hypothesis in this case. In this sense I'm not even sure if this thread belongs in the "Scepticism and debunking" forum if it being there means it is unworthy of cosideration.
On this we probably agree, and if any PF member is interested in starting a thread in which we can discuss Alfvén's work, from a physics/astrophysics perspective (including the extent to which good observational results are consistent with his theories and hypotheses), then I will gladly join.
In short, I don't think that quote has anything at all to do with EC "Theory". It reminds me of the out-of-context ether quotes of Einstein that ether theorists like to throw around.
Except Russ that this Alfvén quote is from a website whose primary purpose (it seems to me) is to push a particular kind of pseudoscience as hard as it can.
