About the risk of big black hole, the CERN have accepted to start the LHC, not only because current theory say that small black hole will evaporate quickly (they don't take risk based on, even consensual, theory), but because Auger observatory have shown that we receive daily huge cosmic particle that are many billions times more heavy (above exaelectronvolt, up to10^20eV), and that the planet have survived since a few trillions years back.
http://www.auger.org/cosmic_rays/faq.html#energy about magnetic fields, the one at LHC are big, but there are many place on earth, where such field are created, or just a little weaker, including in MNR machines. There is also some stars having huge magnetic fields that have been detected. they could tell us about the existence or nonexistence of some feared/expected effects. I heard nothing about exceptional unexpected effect observed. 2011/12/5 Horace Heffner <[email protected]> > ...
