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. Galileo's part in the controversies over theology, astronomy and philosophy culminated in his trial and sentencing in 1633, on
Planets of the Hainish Cycle current estimate. On the other hand, giant stars last 100 million years or so, which is much less time than Earth needed to evolve complex life. It is probable that the native humanoids are of Hainish origin, as are many other indigenous populations in the Hainish Cycle, descendents of genetically modified Hanish colonists from the ancient Hanish colonial epoch, similar to other planets in the cycle. This would account for the successful imbreeding, which should not be possible if they had evolved from completely different biospheres. In 1.5 million years, Eltanin will pass within 28 light years of Earth. At
