(I looked for a Stupid Question section but couldn't find one anywhere - I apologize if this is the wrong section for this question.) If you shoot an arrow at a tree, the arrow will eventually travel half the distance between your bow and the tree. From that point, you could go on infinitely saying the arrow will travel half the remaining distance to the tree. How the hell does the arrow ever hit the tree? If my friends asked me this question, how would I respond to them in a way that makes sense? I'm basically looking for something more than "just don't think about it that way, idiot" because that's all I've got right now. Thanks Great forum by the way, just found it today and have spent way too much time reading already.
