Dave Talbott discusses the "split personality" of Mars --
"But the questions are not being asked. Just consider for example the mystery of the Martian profile as a whole
where you have such a split personality, completely unexplained.
Two hemispheres so radically different. In the North, virtually no craters. In the south dense cratering.
How could that be? We make assumptions about planetary evolution and hold on to those assumptions for decades after they've stopped working. The mysteries surrounding Martian geology
may run far deeper than the general public have been led to believe.
The key piece of evidence is the shape of the planet.
The northern hemisphere is actually lower than the southern hemisphere
and it's not just that that planet was somehow squeezed into an odd shape.
The definitive consideration is the crustal depth.
For reasons that no planetary scientist has explained,
the crust of the northern hemisphere has been excavated.
It's been eaten away, up to 6 miles deep.
And there is one force only that could achieve hemispheric excavation of a planet.
That force is electric discharge in an age of planetary instability and violence."
