you're asking me why but you're expecting me to answer how well the most im gonna give you to that is sometimes there is no why, hell maybe theres never a why. maybe things just happen for no reason at all and we're just left to try and make sense of it. as ive said before, things like gravity and physics answer how things happen. when you ask why gravity affects the ball, you're asking the wrong question because gravity does not have reasoning and you need reasons or things that have reasons to answer why. and ya' know what, the same can be said for how questions. in fact, it can be said for question because when theres a fundamental understanding or explanation of something there's always a deeper and more fundamental understanding and explanation which [b][i]both[/i][/b] religion and science struggle to find. and no i'm not trying to implicate that a god is the reason behind everything, im trying to explain that science and religion have to fundamentally different goals that people confuse for the same goal and if you can't tell the difference between how and why you have no right make scientific or religious inquiry until you do because there is a whole world of difference. so to answer your question of why the ball is falling, its because some random guy threw it in the air or it fell off a ledge how is it falling? gravity reacts with the ball pulling it towards the larger mass (earth) until it makes a complete stop due normal force equaling the force associated with gravity. and religion tried to answer why questions, their best answer was some divine force and then they asked why it does it now please tell me [u][b][i]why[/i][/b][/u] we're here on this big rock flying through space, and you better not tell me the big bang or evolution.
