That we shall probably never know the whole "truth" about the universe does not really matter very much; the fun comes in trying to find out. The natural pattern of current astronomy … is provided by the cryptic unity of nature itself (belief in which is the chief act of faith of the scientist) and by questions astronomers ask today, as their predecessors have done for centuries:
Whence comes the fire of the Sun and the stars?
What is the explanation of unusual phenomena in the sky (in former days, comets and supernovae; nowadays quasars and pulsars)?
How is the universe constructed and what is our place in it?
How did the universe begin and what is its fate (and ours)?
