In the late 1800s, Kelvin and Helmholtz suggested that the Sun stayed hot thanks to gravitational contraction. What was the major drawback of this idea?
A) It predicted that the Sun could last only about 25 million years, which is far less than the age of Earth. B) It predicted that the Sun would shrink noticeably as we watched it, and the Sun appears to be stable in size. C) It is physically impossible to generate heat simply by making a star shrink in size. D) It predicted that Earth would also shrink, which would make it impossible to have stable geology on our planet. E) It was proposed before Einstein's theory of general relativity and was therefore incorrect.
