Under Round Earth Theory, Relativity states that the force of gravity, in higher concentrations, will have an effect on the passage of time. It also predicts that the force of gravity varies over the Earth's surface, which means different parts of the Earth move at different speeds, and accelerate at different rates (as circular motion is acceleration). This is the flaw they point out in Universal Acceleration, why do you not note it in your own theory?
Why has the earth not torn itself apart, if it is round?

This is a fairly intelligent question formulated in the an almost in-cohesive way ;)
Short, simplified answer ... time dilation is not the only effect ... relativity also says that space is contracting (Lorentz contraction) ... so ... if you move faster your time runs slower but your distance also shrinks, so for the outside reference you move with the same velocity. The earth is saved ...
The famous spaceship travelling ... from the outside's frame of reference it moves according to the right speed and across the right distance to its target, but inside the ship the time dilation results in less time passes - but the distance is also shrinking and so it arrives at the same target and nothing is torn apart.
I found a website were someone actually calculated the stress that should exists due to that very idea ... about 5 meter difference per year. Of course, its a site that claims relativity to be a conspiracy ... it does not consider length contraction.
I am sure someone with deeper knowledge of general relativity can give a more profound answer ... especially if we go into issues like the Bell's spaceship paradox or the Ehrenfest paradox (which actually brings up a few issues on rotating objects and geometry) ... all of these problems are complex but are solved under general relativity.

Relativity does not state what you claim, try again.

Actually it does, sorry, try again.

That fundamentally makes no sense. It isn't isn't the space within the object that alters: something doesn't get smaller or bigger when it moves at high speeds, to use the spaceship example. Space just contorts around it, elongating the image.
This just makes things worse for you.

You asked about time dilation within an object ("different parts of the Earth move at different speeds" - from your post) and yes, it exists, it's tiny ... and yes, it leads to tiny changes in space too (Lorentz contraction) ... I gave you the easy, vastly simplified explanation and a few pointers if you want a more detailed one (look at the Ehrenfest paradox, for example). You asked a complex question about relativity and if you don't understand the answer maybe you should stick to easier subjects.
... something doesn't get smaller or bigger when it moves at high speeds, to use the spaceship example. Space just contorts around it, elongating the image.
Space contracts along the directional vector of the movement ... so yes, things get smaller at higher speed ...
This just makes things worse for you.
This was not an argument, you asked, I answered, I am fine if you don't like it ...

General relativity does not claim Gravity is a force.

I gave you an answer ... and information for more details ... it was you who started talking about a problem because of relativity and then stated that you couldn't make sense of the answer ... I feel my answer was as simplified as I could make it ... time dilation and space contraction is no easy subject ...

Semantics, irrelevant to the main point.

The same problem I pointed out before remains.
