How can this be so? Unless the earth is losing gravity. From the gravitational sound waves at Shamballah. Throwing the planet into oblivion.

Guess I don't find it that hard to believe. Very few "natural" substances are impermeable, especially when they are under such pressures and because everything is moving.

Aren’t “Volcanoes” signs that the earths core is leaking? this isn’t “new”.

Another example of useless science performed just to get even more research funds for even more useless science- and then to be presented ignorantly to the public by science "journalists."


Everybody KNOWS the planet's surface recycles itself via plate tectonics-- surface material subducts to become core magma again while core magma rises above to become mantle again. The only "original" rock left at the surface is that in the Canadian Shield....This paper apparently just provides some additional evidence supporting the concept via isotope studies.


Eventually, because energy always moves from high concentration to low, the core will solidify. {Oh, No! Another crisis looming! We need legislation & regulations!}


But let's use a little logic-- We've all seen the Grand Canyon with it's layers upon layers of rock exposed as we scan down the walls. We're told that they have been laid down progressively over time...Doesn't that mean the planet must have been much smaller in it's early history and getting bigger as it collects more & more star dust? No?

Um, gravity is about mass. Whether the core is liquid or solid or moving or static does not alter its mass.

Yeah, I'm not seeing a problem.

Where mantle comes into contact with the core, because of the extreme heat and pressure, the mantle there should be molten, or in a plasma or colloid-like state.

Was the question of whether the core revolves ever confirmed?

Because if it is, then it creates centrifugal forces and since liquids behave as gases, it's going to push through any weak-point in the mantle.

Not on this planet.

On what planet does that happen?

Only the upper part of the mantle is involved in plate tectonics on this planet.

That's the asthenosphere and the rock above it.

It's not the only craton, but it is the oldest. Well, the oldest Earth rock. There is rock that is older, but it's not from Earth.

Earth was molten in the Hadean Eon.

When it cooled 3.8 Billion years ago, that's the start of the Archean Eon.

Most of your gneiss comes from that, although there is Proterozoic gneiss. It's usually all lumped together as Pre-Cambrian.

There's another craton that starts in northern Russia and extends west through the Baltic States, the Nordic States and Scotland, the isles off Scotland and then Greenland.

It was widely believed for a long time that Iceland pushed up through that craton and separated Greenland from Scotland, but the evidence now shows that Greenland was already separated from Scotland before Iceland formed.
