A Dark Star Prophesied

Part of the Springer Praxis Books book series (PRAXIS)


Newton’s theory of gravity was a watershed in the development of science. It seemed to simultaneously provide a highly accurate and comprehensive means of both describing and explaining the motions of the heavenly bodies. Virtually all observed bodies moved according to Newton’s basic rules. The new minor planets that were regularly being discovered after 1801 as well as those age-old harbingers of ominous events, the comets, were shown to obey the theory of gravity. Indeed the return of Halley’s Comet in 1757, two decades after Edmund Halley’s prediction, was widely touted as a monument to human intellect. Nothing in the heavens seemed beyond the scope of Newton’s laws, even pairs of distant stars moved according to the same laws that governed the planets.
