AI Thread Summary
The discussion centers on whether the Earth's roundness can be proven mathematically. Participants argue that mathematical equations alone cannot confirm the Earth's shape, emphasizing the need for physical observations. The Earth is described as an oblate spheroid, which can be mathematically represented, but this does not equate to proving its roundness through equations. Observations such as circumnavigation and space travel are highlighted as more effective methods to demonstrate the Earth's shape. Ultimately, the consensus is that mathematical proof is insufficient without empirical evidence.

Obviously not. The Earth being flat is not inconsistent with mathematics. You have to make a physical observation.

Define "round" it's sort of ambiguous
 
Spherical?

The Earth is actually closer to an oblate spheroid (if I have it right)...yes, this can be shown mathematically.

Probably not since the Earth is not round. :wink:

It has a buldge at the equator...too many donuts.

yea use the formula for the surface area of a sphere 4pi*r2. Then compare it to the actual surface area of the earth. you will see that the numbers do not match proving Earth is flat :D
 
Put simply one could observe that it is possible to circumnavigate the globe, or leave the Earth in a spaceship without seeing the edge. It's not difficult.

And yes, you can't prove that the Earth is round through mathematics, you have to show an observation.
