Holding page for - The Relentless Imperative of  Gravity :-
testing for update
(Continuing the story) :-  Rubbing the Earth away makes it bigger.  Yeah?  .. How?.

Newton's Third Law :- "To every action there is an equal and opposite reaction".   Aphorism or platitude, I'm not sure which, nor which way round the dominoes of action and reaction are, but checking out the likely possibilities I find that keep rubbing the Earth away by erosion is very closely tied to it keep getting bigger.  It's very strange that this quirky behaviour is not taken up by Plate Tectonics since it's pretty good at noticing silly things :-

"Is the crust being pushed up ? Or falling down?" 
"It's falling down. The mantle as subducting slabs, you know (?).  The continents are behemoths /bulwarks - fixed bastions of resistance pushing half-a-world of moving mantle down the gurgler by the slabful, but at the same time they're getting crumpled up into mountains by the soft sediments that get piled up on them."

[unpack this. => ]

Meanwhile, out there, .. on the Big Shippo HMS B.S. P.T. :-
...  " It was a dark and stormy night.  The wind howled, the lightning flashed, the thunder roared and the storm blew, and the rain came down in torrents.  And the captain said to the cook, "Cook, .. spin us a yarn", and the cook began as follows :-
"Y'know, .. it's an odd fact, but wherever we go in the world the Earth's surface is being reduced to flatness.  Ice /snow, wind /rain, glaciers and rivers, and the relentless crash of waves upon the shore such as send sailors to their doom..  they're all working to make the Earth flat as a tack."
[Sailor 1.]  "Aw, .. C'mon Kook, .. not that one again .. "
"About 'flat'.  Everybody knows the Earth's not flat."
"Ah never said it was."
"Yes you did."
"No I didn't."
"Yes you did.  You said the Earth was flat and the other lot were working, which is more than what you do most of the time."
"I said they were working to *make* it flat.  That means it's not already flat. Anyway if your attention's up then here's one for you.  You know how Bad Bart fell off the crow's nest the other day and got wet because of gravity, and how gravity makes it so you never get to sail over the horizon?  Well this is another brick in the wall of gravity."
[Sailor2.] "Belay pin in a fife rail.  How long have you been on this ship, cook?
"Four weeks out from port ever since the King's Shilling, and nivver a regret either me 'earties.  You're as fine a bunch 'o lads as ivver I clapped on.  'Strewth."
"Yeah, .. well, don't go talking about brick walls, gravity and stones of any sort, or sending sailors to their doom.  Not on this ship."
[Sailor1] "That's wimmin, .."
"What is?"
"Luck. Women.  Doom, ..  an' thar be dragons, .. bad luck on ships they be."
"Who's talking about women?  I'm not."
"Well we wish you were, ..   .. "
"If it's bad luck and doom you're looking for just wait till dinner."
"No I'm, ...   "


And so on.

So you can see how the dialogue is shaping up.  The crew are not interested in being sent to their doom upon the sea shore or anywhere else, .. and not very enamoured of the cook's story generally, even though he's about to tell them a very serious thing about gravity. What the cook was trying to say before the crew got off the point and excited about dragons ... was, ...

Meanwhile, .. back at the King's Shilling :-

 Simple Simon :-

 Gravity1 meets Gravity2 meets Gravity3 (Yes?) 
Getting reduced to flatness 1 (once more) => 3.

But it's got to get to the sea, .. which in pre-oceanic times was not that far away, .. in fact that canoe in the bottom right of the picture might easily have been sailing on it.

.. met a Pie-man :-

 Gravity1 meets Gravity2 meets Gravit3 (again).

(.. who would dredge up anything from a barrel of tripe to have you believe in "mountains , tossed high by the collision of plates.")

And this one is already *AT* the sea, ...  ["It's a scale thing.."]  (= Gravity and the relentless imperative of flatness) (I mean roundness) (I mean fla... )   What do I mean?   [=>Azimov:-
"What actually happens is that once scientists get hold of a good concept they gradually refine and extend it with greater and greater subtlety as their instruments of measurement improve. Theories are not so much wrong as incomplete. This can be pointed out in many cases other than just the shape of the earth. Even when a new theory seems to represent a revolution [as P.T. did with Continental Drift - d.f.] it usually arises out of small refinements. If something more than a small refinement were needed, then the old theory would never have endured."

The change from Continental Drift to Plate Tectonics however was not a revolution (although it was touted as such), it merely shifted the important dynamical interface for global deformation from that between the crust and the mantle to that between the upper and the lower mantle as "greater subtlety" was able to be measured.  In fact those developing the change to Plate Tectonics knowingly perpetuated Wegener's ignorance /lack of knowledge (about the ocean floors being mantle and everywhere young) despite being well aware of the inherent flaw within that piece of evidence, .. namely that the breakthrough of the mantle was the same age as the continents they were breaking through - in order to .. .. Well, there were a number of reasons, but principally they were flags of convenience that were hoisted in order to quarantine the 'disease' that had already appeared on HMS S.W. Carey (that the Earth was getting bigger) that threatened to prevent the Big Ship from sailing home to haven, in 'Sunny Palestine'.
So, .. is the Earth round or is it flat?  Is it getting bigger over time, or is it staying the same size like it is right now? Considering the scale of geological time, that is.   And since Plate Tectonics has devised a way to keep the arrow of geological time in the snapshot of 'now' in perpetuity (and commit everybody to keep sailing over an unreachable horizon into the hereafter), where did it go 'wrong' to such an extent that as Azimov says, it only needs a little bit of tinkering to make it right?

 Read more?   Five mentions in the box reminds me to post it.  We're going to sink this clapped-out rustbucket - beginning with the erosion that helps to prove the Earth is getting bigger.  (But that's not where we started either.)
