Evidence for God from Cosmology Richard DeemEvidence for God
The Greatest Discovery (COBE, 1992) l“unbelievably important... They have found the Holy Grail of cosmology” Michael Turner (University of Chicago) l“It is the discovery of the century, if not all time” Stephen Hawking (Cambridge University, UK) l“What we have found is evidence for the birth of the universe. It’s like looking at God.” George Smoot (UC Berkeley - COBE project leader)
