You are just slightly late in discovering tangent lines.

Or is the level slightly curved and you just can't see it?

2,200 years ago a Greek named Eratosthenes measured the circumference of the earth by noticing the difference shadows the sun produced, a stick, and a little math. His margin of error was about 2%.

It is absolutely True the Earth is round.

of course it's *round* -- otherwise it wouldn't fit well on the turtle's back.

i mean, duh.

/turtles all the way down

aeiou, I didn't say perfectly round. It is rounded.

Agreed; to a good approximation it is an oblate spheroid. Variations from this are generally called "mountains." Was there really some point to this question?

I agree. Have you ever tried to put an oblate spheroid on a turtle's back?

Of course not, we live inside.

Bill M. says:
Sure, the planet is really neither flat nor a perfect sphere. By the same logic, the correct spelling of the word "conceive" is neither "conceve" nor "myxxzffphtf". But of course, only an idiot would think that this makes the two answers equally inaccurate.

Isaac Asimov wrote an essay where he addressed that sort of solipsistic argument that mystics and other anti-science people like to make (using the example of a flat vs. round earth, of all things). To quote:

"...when people thought the Earth was flat, they were wrong. When people thought the Earth was spherical, they were wrong. But if YOU think that thinking the Earth is spherical is just as wrong as thinking the Earth is flat, then your view is wronger than both of them put together."

RAS: "Agreed; to a good approximation it is an oblate spheroid."

Differences between polar/equator diameter and circumference is less than .01%. Billiard balls are not as "perfect" a sphere as that...ball bearings only slightly more so.

Yeah, we're talking geometrical forms in physical reality which needn't and cannot be perfect as a Platonic Form for us to basically say, for example, the Moon is round, the monitor is rectangular and so on..

Re Yog-Sothoth, 10-8 6:26 PM: "Differences between polar/equator diameter and circumference is less than .01%." It's actually a bit more than that: the difference is approximately 1 part in 298. Precise values for the equatorial and polar radii have been adopted by the mapmaking community; search for North American Datum 1983 for particulars. Equatorial radius is 6,378,137 m; polar radius is 6,356,752.3141 m (from Wikipedia).
