A line? What the fuck is it? The most straight and the shortest distance from point A to B?... yeah, but I've never seen it in Nature. A straight line actually doesn't exist in Nature. Even Newton's gravity is relative and not (maybe almost) a force that pulls in a straight line towards the center of the Earth. Why? The center isn't fixed and there are other forces bending it as well.... My point is, the line is a man made up thingy that, yeah, comes in handy in a lot of fields but, imo, it states an abstract and utopian representation of something non-existent on this planet or in the universe for that matter.
I would like to hear your opinion on the line concept, Kalister. (if I may?)
Geometry is meant to be an idealization. Its a nice and beautiful world that isn't impinged by reality. The fact that something doesn't exist in the real world doesn't mean we can't create it. We can create some pretty odd things in math, things that are not allowed in the real world. Gabriel's Horn is a nice example.
All that you said about Physics is completely true. Well, Newtonian gravity pulls towards all points of matter, so if you have a idealized planet, we just nicely put the center of mass at the center for most applications. So yes, thats all true.
