What shook me most to this point in life and in understanding the subject matter you are discussing here is when Neil DeGrasse Tyson (sp?) described in the COSMOS series sequel, the endless racing apart/expansion of the universe as discovered by Hubble, that one day every creature or heavenly body would end up in the dark...alone...and never again not alone. That just feels too desolate...destitute...pointless. Se la vi. No?
