    Mysterious Particle From Sun Changing Laws Of Physics!


    We all know the Sun to be playing a part in global warming/weird weather, but, can the Sun be changing the Laws of Physics? Scary...  - Jack.


    Here's the article from Popsci magazine:


    How's this for spooky action at a distance? The sun, at 93 million miles away, appears to be influencing the decay of radioactive elements inside the Earth, researchers say.

    Given what we know about radioactivity and solar neutrinos, this  should not happen. It's so bizarre that a couple scientists at Stanford  and Purdue universities believe there's a chance that a previously  unknown solar particle is behind it all.

    The big news, according to Stanford's news service, is that the core  of the sun -- where nuclear reactions produce neutrinos -- spins more  slowly than the surface. This phenomenon might explain changing rates of  radioactive decay scientists observed at two separate labs. But it does  not explain why the decay-change happens. That violates the laws of  physics as we know them.

    While examining data on radioactive isotopes, Purdue researchers  found disagreement in measured decay rates, which goes against the  long-accepted belief that these rates are constant. While searching for  an explanation, the scientists came across other research that noted  seasonal variation in these decay rates. Apparently radioactivity is  stronger in winter than in summer.


    A 2006 solar flare suggested the sun was involved somehow. Purdue  University nuclear engineer Jere Jenkins noticed the decay rate of a  medical isotope dropped during the solar flare, and what's more, the  decline started before the flare did. The latter finding could be useful  for protecting satellites and astronauts -- if there is a correlation  between decay rates and solar activity, changed decay rates could  provide early warning of an impending solar storm.

    But while that's good news for astronauts, it's bad news for physics.

    Peter Sturrock, Stanford emeritus professor of applied physics and an  expert on the inner workings of the sun, told the researchers to look  for evidence that the changes in radioactive decay vary with the  rotation of the sun. The answer was yes, suggesting that neutrinos are  responsible.

    But how could the nebulous neutrino, which does not interact with  normal matter, be affecting decay rates? No one knows. It might be a  previously unknown particle instead.

    As Jenkins puts it, "What we're suggesting is that something that  doesn't really interact with anything is changing something that can't  be changed."

    Though disaster movies would have you believe otherwise, we should  not yet worry about solar neutrinos warming the core of the Earth. But  perhaps we should worry that our understanding of the sun -- and perhaps  our understanding of nuclear physics in general -- is a lot weaker than  we thought.




    What do you guys think? Some crazy sun activity is coming and set to peak around 2012. Dun dun dunnn... - Jack
