Re: Earth's Core

...spins faster than the surface

*It's confirmed via seismology studies.

So the researchers speculated that if the Earth's inner core is rotating faster than the rest of the planet, then shock waves from waveform doublets would enter and exit through different parts of the core despite originating from roughly the same spot on the planet's surface.

By analyzing the minute changes in travel times and wave shapes for each doublet, the researchers concluded that the Earth's inner core is rotating faster than its surface by about 0.3-0.5 degrees per year.

Re: Earth's Core

Gee, I wonder if we should also post that lethal and non lethal energy pulse weapon too at the same science site?

It kind of like the phaser on Star Trek.

Re: Earth's Core

I'm glad of that discovery as I wrote five years ago in a astronomy children book that different speed core spinning should be responsible for earth magnetism, and that cyclic cinetic energy exchanges between inner solid core and liquid metallic crusts surrounding it should be responsible for magnetic polar inversions. 
This is still to verify.
