Newton's theory of gravity was corrected by Einstein's theory because of ______.
A．a new hypothesis about gravity
B．careful measurements of Mercury's motion
C．new practical considerations of Newton's theory
D．newly predicted observations
Which statement about Newton and Einstein is NOT true？
A．They both committed to the study of space and time and put forward their own theories.
B．Einstein's theory of relativity preceded the theories about the black holes.
C．Newton believed that the laws of motion are different for objects on Earth and in space.
D．Einstein's theory of relativity proved that some of the Newton's beliefs were wrong.
In practice, what often happens is that a new theory is devised that is really an extension of the previous theory. For example, very accurate observations of the planet Mercury revealed a small difference between its motion and the predictions of Newton's theory of gravity. Einstein' s general theory of relativity predicted a slightly different motion from Newton's theory. The fact that Einstein's predictions matched what was seen, while New ton's did not, was one of the crucial confirmations of the new theory. However, we still use Newton's theory for all practical purposes because the difference between its predictions and those of general relativity is very small in the situations that we normally deal with. (New ton's theory also has the great advantage that it is much simpler to work with than Einstein' s!)
