Exposing PseudoAstronomy

God Said Stars Are Made from Water?


This is a quick post that is kinda another “WTF?” post from something that the young-Earth creationist (YEC) Institute for Creation Research’s (ICR) “science” writer Brian Thomas put out in his article, “What Causes a Galaxy’s Magnetism?

About the first two-thirds of the article is basically parroting a press release about a new map of the Galaxy’s magnetic field. The jist of the press release is that a team of astronomers has mapped our galaxy’s magnetic field to higher precision and accuracy than had been done previously with an eye towards studying extragalactic magnetic fields: you need to know what’s in the way before you can figure out what’s going on with a far-off object. It can also act, over time, on slightly magnetized dust and gas within the galaxy.

But – gasp! – we don’t know why the Galaxy has a magnetic field to begin with! As the ICR article states, “Secular astronomers are no closer to understanding what could cause galactic magnetic fields than they were when they first detected the fields over a century ago.” (That’s the first sentence of the article.) You kinda know what’s coming next … a God of the Gaps argument.

From what I can tell – and this is WAY outside of my field so if any astronomer who knows more about this reads this post, please post in the Comments – the statement is true that we don’t really know what caused the Galaxy’s magnetic field to form in the first place. But, a very recent article has an idea that it may have formed from a background field “seed” that became stronger as the Galaxy formed. So it’s not like we’re totally ign’ant, there are ideas out there.

But no, apparently that’s not good enough. Creationists have to figure it out from the Bible, and …

“In 2008, physicist D. Russell Humphreys proposed a Bible-centered model for the origin of magnetic fields that is consistent with the overall strength of the spiral Milky Way’s magnetic field. If God formed the stars and galaxies during the fourth day of creation using water that He had created earlier, and if those water molecules were all originally aligned, their tiny magnetic fields would have combined to form a galactic magnetic field that has decayed to something that looks like today’s observed field strength.”

Yup, that’s right. The premise of this creationist proposal is that stars are made from water. I really don’t think anything else needs to be said at this point.
