Christianity in the 17th century 1640s. In 1610, Galileo Galilei published his "Sidereus Nuncius", describing observations that he had made with the new telescope. These and other discoveries exposed difficulties with the understanding of the heavens current since antiquity and raised interest in teachings such as the heliocentric theory of Copernicus. In reaction, scholars such as Cosimo Boscaglia maintained that the motion of the Earth and immobility of the Sun were heretical, as they contradicted some accounts given in the Bible as understood at that time.

Formation and evolution of the Solar System Immanuel Kant, and Pierre-Simon Laplace in the 18th century. The most significant criticism of the hypothesis was its apparent inability to explain the Sun's relative lack of angular momentum when compared to the planets. However, since the early 1980s studies of young stars have shown them to be surrounded by cool discs of dust and gas, exactly as the nebular hypothesis predicts, which has led to its re-acceptance. Understanding of how the Sun is expected to continue to evolve required an understanding of the source of its power. Arthur Stanley Eddington's confirmation of Albert Einstein's theory of relativity led to
