   Maybe.  I have started reading the book, but did not have time to continue   
   with that yet.  The original talk, I think, is conclusive.  Although, as I   
   found out later, Krauss made a few questionable statements in it (e.g.,   
   there was never a "worst prediction in all of physics" regarding the Dark   
   Energy density, as my professor in General Relativity explained to us this   
   semester: It was never a well-founded assumption that the Dark Energy   
   density should be of the same order of magnitude as the Planck energy density).

   Parse error.

   General relativity and the Lambda-CDM model are not broken; so far they work   
   very well.   
      
   By contrast, alternative theories so far like Modified Newtonian Dynamics   
   (MOND) theories do not actually work because by contrast to Dark Matter   
   they can only explain a subset of observations.

   That is a vacuous statement.

   It is a working theory.  That does not mean that it is the truth.

   That's a stupid question.
