It can exist.  The pull would be roughly normal to the surface.

We already covered this.

Then I don't see what the issue is.  Its solid.  Its correct.  You can't have an argument against it, because if you do you are wrong.  It clearly shows that it would not collapse to a point, or to many points.

So then you can accept that the value (or perceived value so as not to get tied up in semantics) is 9.80665 meters per second per second?  That's at least somewhat refreshing.


Give or take a couple of centimetres per second per second, yes.


Ahhhhhh, I'm beginning to see the light now.

So let's walk through an examination of the data presented.

Given:
1) Earth is an flat infinite plane
2) The earth has infinite mass

And agreeing with the above, if A (Area) would be infinite, then mass too would be infinite.  Are you suggesting that the earth has infinite mass?
Yes.

3) The earth has a density(rho) that cannot be determined since the earth has neither finite mass nor finite area

I'm puzzled by your statement.  Knowing an objects volume (in the infinite plane of a finite thickness argument) and it's mass, it should be elementary math to discover it's density.
Only if its volume and mass are finite.

4) The development of the term governing the acceleration of gravity is governed by:
    http://www.theflatearthsociety.org/forum/index.php?topic=32568.0 which states: g= 2(pi)*G*rho

5) g is accepted as 9.81(roughly) m/s^2

From 4) and 5)
9.81 m/s^2= 2(Pi)*(6.67428E^-11 m^3 kg^-1 s^-2) *(rho)
rho = 9.81*2*pi*(6.67428E-11) [m s^-2 m^-3 kg s^2]
rho= 23,407,945,903 kg/m^2 ( a finite area density of the plane)
This disproves 1) and 2) and 3) and also means that equation in 5) (using Gaussian formulation approximating earth as a plane does not apply meaning the earth is not flat.

Now taking Newton's law of gravity and the Gaussian formulation of Newtonian gravity, the exact same formula you held to be true, so you must accept it only taking the earth to be a shape (let's try a sphere) both reduce to:

g = Gm/r^2

Substituting values assumed for G m and r:
g= 3.986005 E14 m ^3 s^-2/(6.378140E6 m)^2
g= 9.8 m/s^2 matching the observed numbers.

Conclusions
1) Earth is not a flat plane
2) Earth is spherical.
 

Is what we covered.  I never mentioned anything collapsing anywhere.

You misused that equation.  Do you understand what is going on with that math?

It applies to a plane.  I don't see how this proves that the earth is not an infinite slab.

How did I misuse the equation?

The equation applies to a plane, I never said it didn't.  In fact I used it as 5)  Do you dispute any of the givens 1-5?

Yes, 1.  The earth is (obviously) not 2 dimensional.

2.33974223 * 10^{10 kg} / _m² is the surface density if the earth were 2 dimensional. 

Yes, 1.  The earth is (obviously) not 2 dimensional.

2.33974223 * 10^{10 kg} / _m² is the surface density if the earth were 2 dimensional. 

1) All givens were as stated by Parsifal.
2) Feel free to replace plane with slab.  An infinite slab would have infinite mass as well.
Do you agree with the rest then?
How exactly again did I mis-use the equation?

If you replace plane with slab, it changes the equation.  You misused it because its only purpose is to show infinite mass can have a finite pull.  When you use a slab:

It would change the result by a factor of h, still resulting in a finite density, which conflicts with parsifal's assumptions.

And the equation only serves to relate show a lack of relation between x and g, with x being the distance from the plane.

Would you care to plug in an infinite mass and show your assertion to be correct?

The amove example does have an infinite mass.

The density can be finite with an infinite mass and volume.   

For example:
lim(x->infinity) 2x / lim(x->infinity) x = 2

Or, just take the infinite series that means the density for each bit of the earth.

And I picked apart your "Infinite Flat Plane Pull" here.

BTW John you do know that your calculation was made for a "pillbox" earth, right?

No it wasn't picked apart.

No, it wasn't made for a pillbox earth.  A billbox was the surfaced used to surround it.  I explained this earlier to you.

For example:
lim(x->infinity) 2x / lim(x->infinity) x = 2

Please explain how your above example is in the least bit relevant.  Also, please include your functions for mass and volume of your infinite variables and how they are differentiable.

My example is relevant because for some reason you think a finite density for an infinite slab is impossible. 

My functions for mass and volume of my infinite variables?   

Are you just saying words now?

At this point the possibility is irrelevant.  Your claim that it is finite is.
How does your example of 2x/x have any relevance or provide any proof to the possibility of finite density out of an infinite mass and volume?

Yes the functions describing the relationship between the volume of the slab and it's dimensions (which you state to be infinite) and the slab's mass and it's dimensions.

Look, I have no interest in further wasting my time on you.  If you have an issue with the facts, I suggest you dig up his corpse and deal with it with him.

Good day.

Facts?  You can't justify any of your assertions to back up your theory.  You throw out equations that most people don't understand and when questioned on their relevance, which in this case they aren't, you can't validate any of it.

Your linear representation of area, which is variable in 2 directions or volume (variable in 2 constant in 1 in this case), is incorrect.  And if you could accurately represent this you would realize that your claim is false.

I'm done with you.

No it wasn't picked apart.

It was made for a pillbox earth. That's where the "2A" comes from in your formulae. That's why the author used the word "pillbox".

It troubles me deeply that you don't understand your own formulae.

The pillbox is the surface, not the earth.

I already explained how the pillbox was used previously to try to make you understand it.

Yes it is.  Thats where the 2A comes from.
