Newtonian bending of light
Rather, it is the amount of displacement that matters. Einstein's theory predicts a different amount of displacement, or star light deflection, than Newton's theory does. I think this is because in Einstein's theory, matter causes space and time to curve, while Newton's law of gravitation, when thought about in a certain way, only deals with the curvature of space.
Therefore, the popular illustration of General Relativity, balls rolling around on deformable sheet, as well as the common explanation of the solar eclipse experiment, are all somewhat missing the point, as in their simpleness they could just as easily be an illustration or explanation of Newtonian mechanics.
The most significant conceptual difference between Einstein's theory of gravity and Newton's theory of gravity is that Einstein's predicts that gravity causes clocks to slow down.
Curved spacetime is a powerful and very appropriate mathematical tool for describing Einstein's theory of general relativity.

Each browser should use a different color hashing scheme, like HMAC, in order to thwart an attacker from brute force trying to design a similar-colored spoof site as the target. You can fool some of the people some of the time, but not all the people all the time.
