an electromagnetic z-pinch can squeeze plasma with such force that it rapidly compresses.

- The yellow & light green oval represents Earth squeezed in a Z-pinch.
- The green circle represents Earth after release from the Z-pinch and subjected only to normal gravity.
- Magma within the yellow areas in the polar regions would be removed into the green areas.
* Fred points out now that even around the polar regions there would be evidence of crustal expansion, due to the ends of the oval shape flattening to a sphere shape. But I add that there would still be removal of magma inward from below the crust, as Cardona mentioned.





> Fred, ... if Earth was sometimes within a Z-pinch and sometimes not, does that mean that the early biosphere would have grown large during the pinch times and would have been crushed when they ended and Earth returned to spherical form with a thick atmosphere? Or had the atmosphere already been greatly reduced by the time life developed?
In my view, proto-Earth was nearly always within the confines of the Bennett pinch throughout its history. Catastrophic extinctions apparently occurred when proto-Earth was not at the focus of a Z-pinch. Along with this, if I didn't make myself clear earlier, proto-Earth always had a thicker atmosphere, but lost massive chunks of it with each catastrophic episode. For convenience I will only count as significant the five major extinction episodes. What atmosphere we enjoy today is a pale remnant of what may once have existed in the primordial past.
All flora and fauna would have survived and become acclimated under this atmospheric blanket, much as today's sealife in the abyssal depths of the oceans are in equilibrium with their environment. But, after each catastrophic episode, both flora and fauna would have had to adapt to the new environment. Everything about us today is a result of that adaptation.
If you mention any of this, please don't take it out of context. There are still many additional details yet to be worked out in this Escheresque scenario, which is why I put an estimate of the year 2015 as the earliest the book may appear. http://www.flickr.com/photos/joshsommer ... otostream/

It's been demonstrated to my satisfaction that this "supercontinent" or "pangea" idea is absolute bunk. The continents don't fit together well on a planet the size of Earth today. They do, however, fit together almost perfectly on a planet much smaller (around 60% the present size of Earth, I believe) planet. Earth expansion is a logical conclusion of the observed fact that many tons of material rain down on Earth every day from space. Obviously as a result of such a hail of material the Earth's radius is increasing. I believe much of this material is pushed into the interior of Earth in a process much like electroplating, through the "spreading sea floor", where we observe volcanic activity (clear signs of electrical activity).
