...But becoming aware of plasma changes everything. Because gravity can distort atoms and because pressure can preferentially "squeeze" electrons out of lower layers, rock can become susceptible to electromagnetic forces. Because plasma cables and sheets (i.e., electrical currents) have been detected flowing between Earth's magnetosphere and the surface, the circuit must close by passing through the Earth. Because magma is a liquid plasma, it will preferentially carry currents. Because electrical currents in plasma pinch into filaments and tend to form "double layers" (capacitor-like formations), the distribution of currents inside the Earth will be highly inhomogeneous. Electrical heating will cause temperature discontinuities in "lines and lumps." Electromagnetic forces between current filaments and between the layers of double layers will cause enormous and sudden pressure variations.
Why doesn't this show up in seismographs of earthquakes? Or does it show up, then go unrecognized because researchers have no concept of plasma behavior? No one has ever investigated how seismic waves act in different plasma conditions. The seismograph scrawls a single wavy line, but the geologist must interpret it according to a choice among several competing theories. With the awareness of plasma, seismographs no longer provide reliable--or even understandable--information about conditions at depth.
Satellites will update the gravity map of Earth
By BBC News Online science editor Dr David Whitehouse
A new gravity map of the Earth suggests that if you want to lose weight you should go to India, where the pull of gravity is slightly less than it is elsewhere on the planet.
You would be slightly less than 1% lighter there.
The gravity map has been prepared to help scientists plan the forthcoming Grace (Gravity Recovery And Climatic Experiment) satellites, to be launched in a few weeks.
