Wrong analogy. The balloon is full of pressurised gas and in every point
within the balloon the pressure is the same. The Earth is solid, which
melts after someway down, then again becomes hot solid, then cold solid,
then very cold solid at the core, cold enough to support superconducting
currents.

Good.

Bad.

You have allowed yourself to be misled by our resident nutter.

Arindam is the only same person.

The pressure in a balloon in NOT the same at every point.

The pressure in balloon acts outwards on the skin of the balloon and is
the same everywhere upon the skin.
We are talking about a solid thing like Earth which is nothing like a
balloon.

There is a pressure gradient.

No. Same pressure all along the skin.

In fact, that pressure gradient is precisely the reason why it floats.

Ridiculous. The balloon floats as its density is very near the density
of the air it displaces.

It took a real genius, named Archimedes, 2500 years ago,
to see that.

He did introduce the notion of density

I'm sure you can imagine it, if you have practiced enough with Alice,

Pressure is zero at the core as a NECESSITY from the physics basics.
Gravity is the only force that matters there. At the core that force is
zero. So the pressure is also zero as pressure is force divided by unit
area.

But you seem to imagine that heat and pressure are not
transmitted toward the center.

No it is transmitted all around as in a done. Just as you feel no
pressure when in a cathedral. The mass at the top does not crush you.
Over millenia, the center will

approach the temperature of what surrounds it. And the pressure.
Equilibria.

Not. It is in a quasi-stationary state.

The center can only lose heat through the surrounding layers.

So whatever max heat was reached by the center, it will be the last to
be
touched by the cooling of the planet.
