2012 –due to simultaneous polar reversal the gamma for the earth’s core and sun can come close to 4/3 – what happens if the core collapses?

Some scientists are worried about a possible core collapse in earth and some similar effects in the Sun between 2012 and 2030. It is astonishing if you ever think the way earth and the sun maintains its equilibrium with massive loss of mass or momentum. But things can change due to simultaneous polar reversals in the earth and sun between years of 2012 and 2030. The biggest fear is that the core of the earth can collapse creating devastation of modern civilization.

When a violent displacement is quickly made in a compressible object of any kind, the material immediately alters its pressure in response to the change of density. If the density increases, so does the pressure. The steepness of the change in pressure relative to the change in density is measured by a dimensionless quantity that physicists have denoted by the Greek letter γ (gamma).

August Ritter in 1879 proved a remarkable theorem. He showed that if γ exceeds the value 4/3 inside a large astronomical body, the structure of the body persists in dynamical stability. His explanation is straightforward. If γ is large and the density of the body increases due to a rapid compression of the material, the pressure rises so steeply that the force of gravity, though also increased, is resisted completely. Conversely, if γ is large and the material in the body suddenly expands, the pressure falls off so steeply that gravity, though weakened, is able to bring the body back to its original equilibrium state.

Ritter's important theorem applies to all physical situations in which mechanical displacements are so rapid that there is no time for a large amount of heat to be leaked out of the system. These constitute "adiabatic" changes of the system. Inside the Earth, the value of γ for hard rocks is very large, and so the Earth remains stable. Even the Earth's moving atmosphere, and likewise the entire Sun, both of which are completely gaseous, have γ equal to 5/3, making them stable, too.

Traditional physics expects nothing to go wrong for another 6 billion years. But some computer simulation studies are showing signs of trouble in the core of the earth.

Collapse of the core of the earth can cause massive implosions in earth’s crust. That can cause massive landslides, Tsunamis, earthquakes in the beginning and total devastation at the end. Some scientists predict, it has already started with exponential rise in the earthquakes, underwater volcanoes and sudden shift of plates.
