Mercury – the small, hot planet with surprises
by Raymond Strom
The measure of a good model of any kind is to be able to predict what future observations might turn out to be. In terms of astronomy, and particularly the solar system we live in, evolutionary astronomy has not done well. Mercury, the innermost planet is a good case in point. Because of its small size, and the difficulty of sending spacecraft so close to the Sun, Mercury presented a particularly big challenge.
The surface temperature of Mercury on the Sun side of Mercury is about 430 degrees Celsius while the dark side that faces away from the Sun is about minus 170 degrees. There is such a high temperature difference, that if it had an atmosphere, the winds would be hyper-hurricane in force. Evolutionists predicted that Mercury would, according to the Nebular Hypothesis, have an atmosphere, but it is too thin according to their prediction. So they claim that a large impact by a solid body has stripped away the atmosphere. However, there seems to be no evidence for this, as that evidence has been apparently obliterated by later events. Good science!
Similar to the Moon
The diameter of Mercury is roughly 4900 kilometres which is about 1/3 the diameter of the Earth. The diameter of our Moon is about 3500 kilometers, so really, Mercury is similar to our Moon. In fact, its surface characteristics are very similar to the Moon. Curiously, moons of Jupiter and Saturn are larger than Mercury. The surface of Mercury is pock-marked with numerous craters, again, similar to our Moon. So, because of its small size, it was a surprise to evolutionists that it was determined that the density of Mercury is very high, much higher than predictions. It seems that Mercury has an iron core. Because of its small size, and its claimed age of about the age of the solar system (4.6 billion years and counting) the core would have solidified a very long time ago. So the prediction by evolutionists was that there would be no magnetic field remaining around Mercury or a small but steady magnetic field, even though at one time it might have had a strong one utilizing their dynamo theory. Curiously, creation physicist Dr. Russ Humphreys predicted that Mercury would have a strong magnetic field, and that it would be decaying at a significant level (determined to be an 8 percent decline between 1974-75 [Mariner 10 satellite] and 2011 [Messenger satellite]).
So, it appears that Mercury is young, not old as evidenced by the predictions of Dr. Russ Humphreys. This will be a recurring theme as we travel outward through the solar system. Stay tuned.
