My god...this debate is having a lot of comments! thought I would add one.
By the way, CON has done a good job!

Subutai's pictures in R3 blew my mind.

Pro says: "if you take any two points in the universe the shortest distance between them is a straight line"

Is this correct?

DanT, Pro would have had to argue the opposite of that. A geodesic is the shortest distance between two points in spherical or hyperbolic space; Pro would have needed to argue that a geodesic is a straight line in curved space and the perception of a geodesic being curved is just an optical illusion.

sorry I meant pro

If I was PRO I would have argued that a straight line is not curved. Drawing a line on a sphere makes the line curved, and the perception of it being a straight line is just an optical illusion.

PRO could have done so much more with this debate, and it was very disappointing.

btw, I am by no means an expert on this subject, but had I been PRO, I would simply have argued that CON was confusing the quality of a line with the quality of a geodesic, thereby equivocating on the standard definition of a line.

Interesting lesson on what not to do in a debate by PRO.

Hmm...CON is correct that PRO engaged in ad hominem, so conduct CON.

I don't buy the spherical geometry argument. CON also admits that such geometry predicates the impossibility of analyzing anything about the interior of the sphere, and so is not truly 3 dimensional. I side with PRO that such a concept equates to there being an object (the sphere) between what would otherwise be the shortest distance between two lines. Still, CON pretty much dropped the debate, and did not argue over the merits/demerits of spherical geometry, and so does not deserve arguments. Resorting to ad hominem as opposed to argumentation is almost always a sign of a poor debater.

That only applies in cases of Euclidian geometry. The definition of a line depends on the geometry involved.
