I can recommend the book <i>Darkness at Night</i> by Edward Harrison [1] for a detailed look at the history of this paradox. An enjoyable read, and ties it in with several closely related historical debates in cosmology.<p>[1] <a href="http:&#x2F;&#x2F;www.hup.harvard.edu&#x2F;catalog.php?isbn=9780674192713" rel="nofollow">http:&#x2F;&#x2F;www.hup.harvard.edu&#x2F;catalog.php?isbn=9780674192713</a>
