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."
Ignoring possible alternative theories, especially for unknowns, is no different from adhering to dogma on pure faith alone, and damages scientific inquiry.
Oh, you mean just like how the global warming zealots try to discredit anyone who doubts anthropogenic global warming, a.k.a. climate change, because "the debate is over" and we "have a consensus"?
Wow! You must be incredibly proud of your ignorance.
...and I'd be willing to bet that this time is no different....
You are certainly right about that. If there is no God then you are no more valuable than a cock roach, because all life climbed out of the primordial ooze. Only a personal God can give personal value. Science can never prove or disprove God, but you may believe or disbelieve. Every every Living thing that crawled out of the primordial ooze is of equal value, but a human being is a special creation of God and is therefore extremely valuable. Scientists know that there are many parameters and constants, including the earth's magnetic field, which have to be exactly right in order to have life as we know it upon the earth. The probability that all of these came into place by any means other than thinking it is absurdly low. I don't about your God, if any, but mine is a thinking rational being, who is so far beyond man, I cannot even imagine him.
All theory is gray
