Newton's laws are not wrong, merely incomplete and also inaccurate when dealing with situations involving extremes of gravity and speeds close to that of light. This was actually demonstrated during observations of the transit of Venus (iirc - I forget the year across the face of the Sun); predictions using Newton's model were approximate, while those based on Einstein's work were spot on. In fact, the whole of modern communications and GPS technology only work because of Einstein's formulae. That's the eating that proves the pudding: when it can be shown to match up to reality, and lead to further developments that work.
At the age of five, Skagra decided emphatically that God did not exist. This revelation tends to make most people in the universe who have it react in one of two ways - with relief or with despair. Only Skagra responded to it by thinking, 'Wait a second. That means there's a situation vacant.'
