Many scientists feel a sense of awe and wonder in response to the universe which science has disclosed to us. For some, the order and mathematical beauty of nature have religious implications. Einstein's own views were closer to pantheism than to theism, but the order and intelligibility of nature are also compatible with a more traditional religious interpretation. Science can also suggest new forms of the argument from design. The universe has been expanding from an incredibly dense fireball 15 billion years ago, popularly known as the Big Bang.
Some astronomers reject the idea of design.
They suggest that there might be trillions of universes, or a succession of oscillating cycles, each with different fundamental constants, and we just happen to live in one in which the conditions were just right for life. Like a Las Vegas slot machine, our lucky combination just happened to come up. This is pure speculation, however, since it is impossible to find evidence of other universes with which communication is in principle impossible. Unpredictable higher levels of complexity can sometimes arise spontaneously from the dynamics of self-organization. The molecular components of life have particular structures and affinities that seem to reflect a built-in design.
