anyone know of a proof for this? here's my best guess... if you think of "infinity" as an actual "place" (for example, you could say that x is at infinity), then i could kinda see how 2 parallel lines could meet. if you think of "infinity" as only "approachable" (ie x is approaching infinity, meaning it's just getting bigger and bigger and bigger and bigger) then it doesn't seem reasonable that 2 parallel lines would meet. in other words, if you think of "infinity" as a PLACE where the rules of geometry n' such are different, then yes, i can kind of see 2 parallel lines meeting. ==== anyone got a proof / a way of thinking about it?
