Students have asked these similar questions
The most significant validation of Einstein’s Theory of General Relativity required the observation of stars that appear near the Sun in the sky. Due to the predicted curvature of space caused by the Sun, what were the stars expected to do when the Sun appeared near them in the sky? Why couldn’t astronomers just go out at any time and take pictures of this effect? So what did they have to wait for? Did astronomers validate Einstein’s prediction?
Why do scientists consider Einstein's General Theory of Relativity to be a better theory of gravity than Newton's theory of gravity?
a) Newton's theory was never useful, so it had to be replaced by something.
b) The two theories always make very different predictions, and only Einstein's theory works.
c) Einstein's gravity makes correct predictions in a few cases where Newton's theory does not.
d) Einstein's theory is newer, and scientists always prefer newer theories.
Some people dismiss the validity of scientific theories by saying that they are “only” theories. The law of universal gravity is a theory. Does this mean that scientists still doubt its validity? Explain.
