Segment 4 of God and the Big Bang is very short. First, it highlights the fact that the Big Bang had to have happened in an extremely precise way in order to produce our universe. It also discusses the existence of something astrophysicists call “dark matter,” the material in the universe that is not visible (because it is dark, not light-emitting or reflecting) but is crucial to galaxy and star formation. We know that dark matter is about five times more abundant than the observable material in the universe!
Deliciously mysterious, isn’t it?
This is one more example of the fine-tuning necessary for the existence of intelligent life. I love the quote from Paul Davies (physicist, cosmologist and astrobiologist working at Arizona State University):
The laws…seem themselves to be the product of exceedingly ingenious design. If physics is the product of design, the Universe must have a purpose, and the evidence of modern physics suggests strongly to me that the purpose includes us.
