Stellar Motionsus, and as much as 57′ for Arcturus, both exceeding the apparent diameter of the Moon. Since Newton’s law of gravitation was established, it should be no surprise — on the contrary, it had to be expected that stars must be in some state of motion, to counteract a possible collapse due to gravitation.作者: 細胞 時間: 2025-3-26 13:45
Stellar Distances a baseline would seem to hold some promise of revealing annual parallactic changes in the positions of the ‘fixed’ stars. These shifts were not observed for three centuries after Copernicus; and in the meantime the heliocentric viewpoint was not acceptable to many astronomers, Tucho Brahe (1546–1601), for instance.作者: Multiple 時間: 2025-3-26 19:41 作者: Addictive 時間: 2025-3-27 00:01
