whats keeping us together?

Why would they fall off?

what is keep the earth from falling apart?

Why would they fall off?

Because they are on the bottom. and gravitation would be pushing them down.

Supposedly the Dark Energy that is accelerating us through the universe would prevent that from happening.  This magical energy is responsible for what we know as gravity, keeping the sun and moon from smashing into us and keeping our atmosphere in, among many other things.

Then why does the FES say that you would fall off a flat earth?

There is only one member of the forums that I know of that can tell you what really happens when you get to the ice wall.  He bungee jumped off of it, and damn if he didn't forget his camera so he could get us a snapshot of the turtle.  I was very upset about that myself.

Try standing on a beach ball.

beach balls don't have gravity.

Gravity pulls you towards the center of the object, not universly down, so "down" would be relitive to where you were standing. If north were "up" and south were "down" you would still be pulled to the center of the object therefor still being stuck to it. Also the earth is alot bigger then a beach ball...a ant or other small animal could stand on top of a beachball easily...and if they were small enough it would look flat from their postition on it.

Go to high school, take physics, then come back here and argue from an educated perspective.

what part of that is wrong?

graivty is determined by mass of a object and distence you are from it's center. If the sun became a black hole right now...we wouldn't be sucked into it becuase we would be no closer to it's center and it would have the same mass (just more compact), however a ship travelling towards it would get more of a pull the closer it came. So in RE you are being pulled towards the core of the earth, and gravity would be slightly different on the equater where it puffs out (not enough to tell) this also explains how in RE you can excape the earths graivty.

Gravitational force = (G * m1 * m2) / (d2)
where G is the gravitational constant, m1 and m2 are the masses of the two objects for which you are calculating the force, and d is the distance between the centers of gravity of the two masses.

Please show mathematically that the gravitational field generated any object is directed towards its centre. Also, please specify whether you mean its centre of volume or its centre of mass.

centre of mass..

and I know the inverse square law shows it somewhat...well how it would work anyhow. But it makes sense that for a item of a certin mass, something futher away from it's center is getting less of a pull then something closer to it's center, that both things are being pulled to the center.

I'm sure there is somekind of math proof that shows it *shurgs*

So basically, you don't know what you are talking about. I see.

If north were "up" and south were "down" you would still be pulled to the center of the object therefor still being stuck to it.

Of course they don't.  They have gravitation, however.

Gravity is a fictitious force that arises when a non-inertial observer adopts an inertial frame of reference. In other words, it doesn't exist.

He just likes being a prick when people say gravity instead of gravitation.

so if the gravitaional force isn't pulling towards center of mass where is it pulling to?

That depends on the shape of the object and the position of the observer. For perfectly spherical objects of uniform density, the gravitational field always points towards the centre of mass, which is in the centre of the sphere. This allows for good approximations to be made within the solar system, since most large bodies are very nearly spherical with close to uniform density - or at least, radially symmetrical density. However, in general, it is not true to say that an object will attract an observer towards its centre of mass.

Under Flat Earth theory gravity is caused by some arbitrary Hand of God pushing the earth up at 9.8ms^-2.

Try standing on a beach ball.

Nope Einsteins relativity doesn't have a whacking great hand of God pushing a flat earth through the universe.

Under both Newton and Einstein a mass is able to generate its own forces.

The force of gravity, fictitious or not, is generated by mass. (Or, if you're a photon, energy.)
