In the meantime cosmologists have become increasingly convinced that our Universe does contain a low density of matter and a cosmological constant. The preferred cosmology is therefore a spatially-flat Universe with a density parameter Omega0 = 0.3 or so.
This is a good time to stress that if there is a cosmological
constant, the simple relations between geometry and destiny of the Universe
in Table 5.1 no longer necessarily hold. The cosmological constant allow
such possibilities as a closed Universe which expands forever, or an open
Universe which recollapses. In extreme cases there might not even be a
Big Bang, though those parameters appear to be excluded by observations.
Back to the home page of the book's first edition.
I thought I should add something new to indicate that I do update this page from time to time. But as it happens things have been fairly stable and so there isn't really anything to add at this point. However you might be interested to know that a new edition of the book will be out in early 2003 which will include updates and quite a bit of extra material.
I will not be updating this page further once the second
edition is out, but if you go to its home page
you can read its new developments section.
