Observation:
1. At the mid-Atlantic ridge, ocean crust is spreading at 5-10 cm/year
2. At the east-Pacific rise, the spread is ~13 cm/year

Hypotheses:
A. The earth is expanding
B. The crust "recycles" as in convection cells [aka plate tectonics]
C. <whatever>

Consideration:
If A. is true (and B. is not) then the earth' radius is expanding
(at least) on the order of 20/pi cm/year.

Non-observation:
There is zero observation of any radial increase. There is the
counter-observation that GPS (which is based on math assuming a
constant earth radius[*]) works.

Fudging:
Attempts to say "other things are going on to hide the expansion"
are attempts by lunatics to deny their lunacy.

[*] You can't escape into the Gaussian equivalence of a spherical
mass with the entire mass at the center, because tidal effects will
intervene. If the earth is expanding, there _will_ be (unobserved)
effects on satellite orbits, and on the data-reduction of their
signals to calculate ground positions. That is aside from the
_serious_ questions about density changes [if the earth's mass
is unchanging] or conservation [of anything physically important]
if not.

Expanding or not you can find seashells atop mountains.

Would _any_ of the expanding earth proponents care to actually
address the issues, instead of indulging in verbal diarrhea? All
of you look like crackpots from where I am sitting and reading.
