Crustal Prediction

Part of the surface of Mercury, as imaged by MESSENGER

The earlier post for the 27th has been removed. In its place is another astronomy article, Mercury’s Magnetic Crust Fulfills Creation Prediction:

The planet Mercury provides many clues to its unique and recent creation. For example, Mercury’s density and composition don’t match planetary evolution models, and its surface geology and magnetic field are too active for it to be billions of years old. New data from the MESSENGER—the spacecraft that has been probing the dense planet’s surface since 2004—confirms another creation-based prediction made in 1984.

Yes, we return once again to MESSENGER – and for perhaps the first time Thomas has remembered to give the craft its proper capitalisation. Brian has three ‘citations for his second sentence, all to articles written by him about MESSENGER findings in the second half of last year. They are:

Messenger Spacecraft Confirms: Mercury Is Unique. This article points out a number of features of Mercury, including high levels of sulphur, that are unexplained (or at least were at the time). As I said then, just because we don’t know how they came to be does not justify jumping to creationism.

Mercury’s Fading Magnetic Field Fits Creation Model. I originally concluded that, given the numbers quoted, the field of Mercury was apparently fading far too fast for the ‘creation model’ – it would require moving the creation date even closer to the now, and would be biblically impossible. However, with the help of Stuart Robbins and a copy of the paper itself, I discovered that it could not even be concluded that the field was fading. What actually happened was that far more detailed results from MESSENGER compared with that from Mariner 10 (which merely made a flyby) caused a significant reduction in estimates of the strength of Mercury’s magnetic field. This is not the same as saying that the field was noticeably stronger in the 1970’s than it is today.

Mercury’s Surface Looks Young. The presence of ‘volatiles’ were claimed by Thomas to show that Mercury is young, though in reality they probably just demonstrate that a small part of the surface is (geologically) recent.

So that’s all he’s got there. Continue reading
