Contention - maths proves that in theory moving objects should never touch each other, physics shows the opposite. Simple example - 1 stationary object(eg. - a wall) and a fly flying toward it. Say the fly is 1 metre away from the wall. In 0.5 sec she is 0.5 metres from the wall. In 0.9 sec she is 0.9 meters from the wall, in 0.999 sec she is 1 mm from the wall, in 0.9999999999sec she is 0.000000009mm from the wall. In 0.9999999999999999999999999999 sec she'd be 0.0000000000000000000000000009mm from the wall and so on. Obviously, the distance between the fly and wall cannot and will never ever become zero. Yet practice shows that the fly lands on the wall and makes that distance zero. How is this possible?
