   I see.   
   This was way beyond your mental abilities,   
   so all you can do is to babble nonsense like this:   
   > Sure, and in a theory of sharks eating grass

   I will give an advise.   
   If a post is above your mental abilities,   
   and you understand nothing - don't respond.   
      
   Babbling nonsense will only make you look stupid.
