Hi pete - welcome back!

I decided to read about the work of Dr Russell Humphries here:

http://www.icr.org/article/beyond-neptune-voyager-ii-supports-creation/   

(I can't seem to make the 'blue clicky' thingy work - so readers will have cut-n-paste the link into their browsers)

I note that this work was published in 1984 in a publication called 'Creation Research Society Quarterly' - "a peer-reviewed creationist scientific journal" (based in North America - surprise, surprise!). Forgive my scepticism, but I can't help noting that Russell's theory is based upon "God rapidly transform[ing] water into other materials" (and then a miracle happens!?).

Anyway, it's possible to contrast that account with a scientific view (as opposed to a quasi-religious view based on the Bible, God and miracles) of planetary magnetic fields here:

This account (in proper scientific fashion) freely admits that we've still got a lot to learn about planetary magnetic fields but nowhere does it suggest that we're desperate enough yet to invoke miracles or to shove God and the Bible into the gaps in our knowledge.
