Heart of Earth's inner core revealed

BBC ^ | 10 February 2015 | Rebecca Morelle

Research from China and the US suggests that the innermost core of our planet has another, distinct region at its centre.

Yeah, that would be Pellucidar

[mcshot]

Wonder where the vast underground oceans are that I’ve been reading about? Most interesting rock we inhabit - will mankind find another or perish as a species?...Oops slightly off topic.

[moose07]

A real let down , isn’t it !

Without being able to drill into the heart of the Earth, its make-up is something of a mystery.

Ninety-nine percent of American "journalists" would have written "...somewhat of a mystery."

[Arthur McGowan]

Huh? Isn’t that the “equator”?

[moose07]

The inertial axis, apparently.
I can only guess that it is misaligned because the earth isn`t a sphere.

[samtheman]

Prof Song and his colleagues in China say this data suggests that the Earth’s inner core - a solid region that is about the size of the Moon - is made up of ... green cheese.

(sorry)

[moose07]

Well the Moon is made of cheese. So if it is moon size, it too could be made of cheese.
Humour makes the world go round....not this scientific stuff. :)

[samtheman]

On an even sillier note, let’s talk about Professor Xiaodong Song.

Xiao in Chinese means “little”.

So is this the real Professor Little Penis Music?

What is an “equatorial axis”?

...

I think it’s an arbitrarily chosen line that passes through the center of the Earth and the equator at two points.

[moose07]

Little pillar , treasured tree. Or something like that.
Sounds similar. :)

[samtheman]

Anyway, I for one am glad the core is molten iron, so that the rotation of the earth creates a magnetic field, so that the solar wind doesn’t blow all our atmosphere away.

[Covenantor]

Off shore tech help?

[Arthur McGowan]

Must be caused by global warming. Or capitalism.

“The Equatorial Axis is the intersection of a sphere’s surface with the plane perpendicular to the sphere’s axis of rotation and midway between the poles.”

What you are describing is the Equator.

My question was rhetorical.

[moose07]

Makes about as much sense. :)
