Of possible interest to your list.

That’s deep.

I don’t see the Obama Economy represented here? Was there no room on the chart?

Current measuring devices are insufficient to accurately probe those depths ...

[Dahoser]

Such a great graphic and yet a usage mistake for O:

Peek of the Rocky Mountains: 14,400 ft
(Peak of Everest: 29,029 ft)

[Phinneous]

Anyone know the science behind the declared depths of the mantle and deeper? Or the earth science that yields these theories? (I mean, if we’ve never been closer than 65,000 feet to the mantle... How the heck do we know a thing? From observing planetary development?)

According to Al Gore it is millions and millions of degrees of heat.

To the best of my knowledge, the mantle and core depths are based primarily on echoes through the earth of earthquakes, underground atom bomb tests and other large underground noises. Similar to the way underwater things are measured with sonar, I think.

And somewhere under the brick and steel of a nondescript building we have made contact with out le-leader.... MARK LEVIN!

[GraceG]

The Science behind Mark Levin's bunker!

:P

[TalonDJ]

Echoes change when the hit that area. So we know there is a change of structure/density/substance at that point. That is why they are called discontinuities.

[Phinneous]

Inference upon an extrapolation upon a theory. There’s little men down there catching the waves and shpritzing them back out into the other hemisphere at different velocities to trick us.

Interesting, thanks NYer.
