Subject: Re: Big Bang density


Well, Urs, regarding your big bang comments, the observed evidence is
supposedly 13-14 billion years old. Theories can be thought of as
interpretations of observations, and observations this far removed leave
lots of room for interpretation. The specific evidence you cited is not as
challenging to our understanding. But where is the evidence that suggests
the more difficult to understand aspects of the theory, and what are the
other interpretations of this evidence? This question is rhetorical, I
don't expect you to round up all this information for me. I'm just
responding to your comments...
