The Universe at Large
註釋How large is the universe? How old are the galaxies and stars? How rapidly are the distant galaxies receding from us? Why, if there are countless stars in the universe, is it dark at night? What goes on inside stars... and between them? How did the universe start and where is it going? These are some of the ageless questions Hermann Bondi considers in The Universe at Large, a brilliant speculation on the findings of modern astronomy. Against the background of conflicting "steady-state" and "exploding" theories of the universe, Bondi examines the contributions and insights of men like Einstein, Eddington, Hoyle, Hubble, and Lemaître. Cosmological considerations are brought closer to hand by applying our revised understanding of the universe to natural phenomena -- including the Aurora, sun and moon tides, the earth's magnetism, and the wobble of its axis.
