But if by 'God,' one means the set of physical laws that govern the universe, then clearly there is such a God. This God is emotionally unsatisfying... it does not make much sense to pray to the law of gravity."
"We are star stuff harvesting sunlight."
"Somewhere, something incredible is waiting to be known."
