Ocean Currents Proposed As Cause of Magnetic Field

pjt33 notes a recently published paper proposing that ocean currents could account for Earth's magnetic field. The wrteup appears on the Institute of Physics site; the IOP is co-owner, with the German Physical Society, of the open-access journal in which the paper appears. This reader adds, "The currently predominant theory is that the cause of Earth's magnetic field is molten iron flowing in the outer core. There is at present no direct evidence for either theory." "Professor Gregory Ryskin from the School of Engineering and Applied Science at Northwestern University in Illinois, US, has defied the long-standing convention by applying equations from magnetohydrodynamics to our oceans' salt water (which conducts electricity) and found that the long-term changes (the secular variation) in the Earth's main magnetic field are possibly induced by our oceans' circulation."

....I can pretty much guarantee that astrologers would have no idea what you're talking about....

Current scientists have no better idea and don't truly know what makes the earths magnetic field. My assertion that God just created it that way, so that we could live upon the earth and worship him is just as valid. Scientists think they know how our world works, but the more answers they get, the more questions they get as well and so they are not much further ahead than our ancestors. Despite all of our technology, we still have not learned to live in peace with one another but have made Weapons of Mass Destruction which to possibly annihilate the entire human race.

"If there is no God then you are no more valuable than a cock roach"

Your just one of billions who have been brainwashed into beleiving that you are nothing without god. I genuinely feel pity for people who's self worth is defined by thier sycophantic relationship with their god.
