Mercury Troubles Deep-Time Scientists
Many of the planets in our solar system are recalcitrant toward deep time, as seen from Pluto at one end and Mercury at the other. There is a frequent problem for cosmology in that planets and moons are showing signs of relative youth, not billions of years. Indeed, our own moon shows geological activity.
Mercury is the smallest planet in the solar system, only slightly larger than dwarf planet Pluto. But it has a magnetic field (as predicted by biblical creationist Dr. D. Russell Humphreys). It is also showing recent geological activity.

The analysis of data from the MESSENGER spacecraft has revealed evidence of recent tectonic activity on Mercury—activity caused by the ongoing cooling of the planet’s interior. This evidence is in the form of small fractures (or grabens) incised into long embankments, called lobate scarps. As Mercury’s interior cools, it shrinks. As a result, thrust faults form in the surface, forcing part of the terrain up and over another piece of terrain, producing scarps. The conventional thinking has long been that this shrinkage began billions of years ago.However, smaller fracture-bound regions, called grabens, incised into the thrusted scarps, indicate more recent geological activity. Debris from meteorite impacts, as well as the tendency of raised portions of the crust to sag and flow downhill, should have erased and filled in the grabens.
