>You have to realize what you guys are saying. You are saying that gravity makes a distinction between flying eagles and plastered down oceans, helicopters and flying projectiles, now do you guys embrace this as fact / true or not? Gravity does not make a distinction. You are making a distinction. Gravity only exerts a straight line force towards the center of mass of an object. Water is not trying to escape. It exerts no force of its own to escape gravity but an eagle does (or helicopters too). An eagle could not fly in a vacuum. It must exert energy on the atmosphere molecules in order to fly. The atmosphere molecules are also held in place by gravity, but being a low viscosity fluid, it is more easily moved by thermal energy causing currents and by mechanical forces imparted by objects. Fluid dynamics is complicated, but it is very understandable if you learn what makes it work. Bullets (flying projectiles) don't fly per se. They simply fall over distance. They are not able to overcome the force of gravity and fall towards the center of mass at a measurable rate. A bullet moving through a vacuum would fall towards the center of mass as well, albeit slightly faster as it would not be colliding with air molecules on the way down. If flying projectiles didn't work the way they do, there would be no way of hitting a target precisely when an artillery crew serves a shell. Math models the projectile's movement very well and we can accurately hit targets because of that. How would that work if gravity didn't do what it does? I don't "believe" science. It's not a religion (if you do it right) and does not require faith, a belief system or feelings. It just doesn't care what you believe in. It just does what it does by the physical laws of the universe and your opinion about it doesn't matter one iota.
