One of the amazing discoveries of physics is the extremely precise fine-tuning of certain constants found in the laws of nature. These constants must be set exactly right in order for life to exist anywhere in the universe. Michael Turner, an astrophysicist at the University of Chicago and Fermilab puts it this way: “The precision is as if one could throw a dart across the entire universe and hit a bullseye one millimeter in diameter on the other side.”
Given this amazing fine tuning, there are only three possible explanations: chance, necessity or design. Since there are no reasons to believe the fine tuning is necessary (i.e. it must be this way), some people have held that it is the result of chance. But is this the *best* explanation? Many philosophers and scientists argue that the fine tuning is best explained as the result of design. And if the universe has been designed then there must be a designer who brought about that design.
The next question becomes: Who is the designer? From physics alone, one cannot make any conclusions. But through philosophy (i.e. other philosophical arguments) one can conclude that this being must exist outside of space and time and is very similar to what theists describe as God.
