Summary

The possibility of the multiverse bean with early steady-state theories postulating causally unconnected regions, a standard Big Bang where spatial cross-sections are flat or open, or even an eternal inflationary universe. These cosmological options present a philosophical challenge to a realist understanding of the universe that is addressed through a discussion of the CMB’s central relevance in it in the chapter.
