Moontanman Posted February 22, 2013 Posted February 22, 2013 Is evidence of a new force carrying particle lurking inside the Earth? A new fundamental force is being explored this force the "long-range spin-spin interaction" could explain some of the processes inside our own planet. http://www.livescience.com/27324-earth-mantle-new-unparticle.html
swansont Posted February 22, 2013 Posted February 22, 2013 Not a terribly good article, I'm afraid. Unparticles are not part of the standard model they are part of an add-on to it, so saying that they are predicted is pretty meaningless — they are a prediction of a conjecture, which you can't assume is true. And the experiment didn't find them, so any discussion of effects is pure conjecture. What the experiment appears to have done is limit the scope of their interaction. IOW, it went in the direction of ruling them out. It's a pretty enthusiastic tone for an experiment that found nothing. 2

Reading ajb's Blog article and the previous post link on unparticles, I feel a need for an asprin and an explanation in clear English. What with unparticles, virtual photons, and spin-spin that is not really spin and other vaporous things ,all happening miles away deep in the earth, I can't quite get my mind round it , without getting a headache. Any chance of one of your clear type explanations ? . Edited February 23, 2013 by Mike Smith Cosmos
