As the legend says, an apple fell on Newton while he was under a tree, it made him wonder why did the apple fall **down** on him.

We now know that it is because of Gravity. But how can we prove that Gravity is real?

Let’s take a 1KG of stone for example. When we measure the force it exerts on the ground, we find that it is 10N (assuming acceleration due gravity to 10m/s^2). If we take a 2KG stone, the force exerted would be 20N. We can thus make a formula to calculate the force exerted **F** by an object of mass **m**

F = ma

F = m x 10

Despite not seeing gravity or knowing the “why” of how objects with mass attract to each other, we have a way of verifying this unknown force. This unseen force always behaves as predicted.

Have we been able to prove that 1 prayer equals 1 life saved at a hospital. 4 prayers have saved 4 lives? I haven’t seen such analysis being published yet. Maybe someone should start finding the correlation. We might be able to have the most solid proof that God exists, scientifically!
