Universal Gravitation

I don't think the earth is an infinite plane.  It almost defies reason.

Infinity is a hard concept to grasp, I agree. But the Round Earth Theory also holds that the universe may be infinite. Therefore; we have a potentially infinite universe in either model.

Technically, if Space-Time is flat then the universe and the earth will stretch out perpetually. If the Space-Time is curved then the earth and universe will eventually wrap back around itself.

The Earth is not infinite, don't listen to his bull. If it was infinite, how did someone come up with a radius for it?

The diameter listed in the FAQ is simply the radius of the known world. The circular area of our plane which is basked in light. There are still vast uncharted lands beyond the coast of Antarctica where the sun does not shine, where temperatures and pressures approach absolute zero, and where life cannot possibly thrive.

The diameter of our known local area can be derived from Eratosthenes' shadow experiment, which studies the area of the sun's light upon the earth. It can also be derived from expiatory distances between the North Pole and South Pole (the South Pole is a circular track of land beyond the coast of Antarctica where the magnetic field lines are vertical). Additionally, the diameter can be derived from the circumference of the equator (the inner middle circle of a circle doubles as its diameter).

It's important to note that the circumference of the Round Earth, 24,900 miles, is exactly the same as the listed diameter of the Flat Earth.

wrong, Tom! the flat earth would have more than DOUBLE the circumference of the flat earth; 60,000 miles is the normal estimate of the "ice wall" given in other posts.

and people HAVE crossed antarctica from edge to edge without reaching absolute zero areas!
there is NO part of the REAL WORLD that is unknown, except maybe some thick jungles in africa.

HUNDREDS of people have explored antactica, including Ross, for whom the "ross ice shelf" was named. now you claim ALL of them are part of your "conspiracy"?

why don't you go to antactica YOURSELF and see?!

I have no fucking clue what you were trying to say?  The circumference of a flat earth is double that of a flat earth?

The circumference of a round earth ( of a sphere? wtf? ) is double that of a flat earth?


The circumference of a flat earth is double that of a sphere ?

damn, i said it wrong again: i meant the FLAT earth would have a circumference of 60,000, while the ROUND earth is 24,000.

btw, RErs say the moon is 240,000 miles from earth.

How does a sphere have a circumference of  24,000 ?

or was that 24,000 miles in DIAMETER?

The circumference of the Round Earth is the diameter of the Flat Earth.

What's hard to understand about that?

that would only be true if NOTHING south of the EQUATOR existed!

The fact that it doesn't make any sense.

The length of the equator of the Flat Earth is equivalent to the circumference of the Round Earth.

no, the circumfrence of the flat earth is at least twice that big!

that would only be true if NOTHING south of the EQUATOR existed!

The figure for the Circumference of the Round Earth is also the figure for the Diameter of the Flat Earth.



If you are having trouble grasping the concepts of "circumference" and "diameter" perhaps you should consult a nearby high school geometry teacher.

The length of the equator of the Flat Earth is equivalent to the circumference of the Round Earth.

The inner middle circle of a circle is also equivalent to the diameter of that circle.

no, the circumfrence of the flat earth is at least twice that big!

You're an idiot. Please learn the definition of circumference and diameter.

you are completely missing the point!
let me try an analogy: if you peeled an orange and spread the peel out, it would cover more of the table than if you simply squashed the orange flat without peeling it.

the SURFACE AREA of the two need to be equivalent for any true comparison!

i am talking about the difference between 2-d and 3-d!

Sure, there is a difference in surface area. I never claimed that the surface areas between the two models was the same. The Flat Earth model has bigger oceans. I was referring to how the figure for the Round Earth's circumference was equivalent to the figure for the diameter of the Flat Earth, all based on different interpretations of the same exploratory distances and shadow experiments.
