Nebular Hypothesis Quotes (1 quote)
One thought I cannot forbear suggesting: we have long known that “one star differeth from another star in glory;" we have now the strongest evidence that they also differ in constituent materials,—some of them perhaps having no elements to be found in some other. What then becomes of that homogeneity of original diffuse matter which is almost a logical necessity of the nebular hypothesis?
L.M. Rutherfurd, 'Astronomical Observations with the Spectroscope' (4 Dec 1862), American Journal of Science and Arts (May 1863), 2nd Series, 35, No. 103, 77. His obituarist, Johns K. Rees, wrote (1892) “This paper was the first published work on star spectra.”

In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
