Mars polar sublimation and Saturnian icy moons
- I am amazed at the similarity between the flat bottomed depressions on
Tethys and Hyperion and the same sort of structures on Mars. On Mars
we know several things about the polar regions.
1. They are largely made of water ice, although in the winter, CO2
covers the ice.
2. On both poles, as they alternate to summer, the CO2 evaporates and
then the water begins to sublime away. Pits in the surface expand
from year to year.
3. The pits have flat bottoms. The larger pits sometimes have
central islands or elevations that also eventually sublime away.
4. In some areas we see erosion on the upper areas of gullies and
depressions at high latitudes. The erosion usually tapers off with
distance from the rim.
5. On Hyperion the depressions have similar erosion features on the
upper walls, the pits have flat dark bottoms, the dark material is not
thick, because in at least one case an impact crater in the dark floor
punched through to light material and has rays of light material
around it. On Tethys the depressions are light in color and the walls
also have erosional features. The pits are sometimes odd shaped, not
at all like impact craters.
The following are views of polar erosion features from Mars. These
may be helpful when examining the eroded depressions on icy Hyperion
Were the icy moons of Saturn once warmer? Did they also sublime some
of their ices off? One of them, Enceladus, is clearly doing so right
now and has geological evidence for recent changes to its surface.
Tethys, has global evidence for enormous change - a huge rift valley.
Was the solar system once much smaller? The Bible states that the
heavens are expanding. Why is it that when we look at the most
distant objects in the heavens, they clearly are so different looking
than local objects? Why do the most distant objects show evidence of
motions unlike what we see locally? Why is the light from all
primordial atoms shifted in color? The Bible has no mathematical
formulas. Yet what it states is clearly supported by simple evidences
in the heavens. It says everything in creation is subject to
inutility. The whole creation is in bondage to decay - phthora - the
degeneration of matter. Clearly matter changes, and that is the most
important thing you can think about the physical universe. How can we
reconcile the Bible and science? We can't, because the Bible denies
the historical, elementary assumption that is the basis of scientific
reasoning. God says at some punctual point, He will make foolish the
wisdom of the world. He even spells out the very thing that totally
defeats the greatest system of rationality the world has ever known.
That will result in everlasting praise and glory for Him.
