The anthropic principle says that the universe appears “designed” for the sake of human life. More than a century of astronomy and physics research yields this unexpected observation: the emergence of humans and human civilization requires physical constants, laws, and properties that fall within certain narrow ranges—and this truth applies not only to the cosmos as a whole but also to the galaxy, planetary system, and planet humans occupy. To state the principle more dramatically, a preponderance of physical evidence points to humanity as the central theme of the cosmos.
Support for the anthropic principle comes from an unwavering and unmistakable trend line within the data: the more astronomers learn about the universe and the requirements of human existence, the more severe the limitations they find governing the structure and development of the universe to accommodate those requirements. In other words, additional discoveries are leading to more indicators of large-scale and small-scale fine-tuning.
In 1961, astronomers acknowledged just two characteristics of the universe as “fine-tuned” to make physical life possible.1 The more obvious one was the ratio of the gravitational force constant to the electromagnetic force constant. It cannot differ from its value by any more than one part in 1040 (one part in ten thousand trillion trillion trillion) without eliminating the possibility for life. Today, the number of known cosmic characteristics recognized as fine-tuned for life—any conceivable kind of physical life—stands at thirty-eight. Of these, the most sensitive is the space energy density (the self-stretching property of the universe). Its value cannot vary by more than one part in 10120 and still allow for the kinds of stars and planets physical life requires.
Evidence of specific preparation for human existence shows up in the characteristics of the solar system, as well. In the early 1960s astronomers could identify just a few solar system characteristics that required fine-tuning for human life to be possible. By the end of 2001, astronomers had identified more than 150 finely-tuned characteristics. In the 1960s the odds that any given planet in the universe would possess the necessary conditions to support intelligent physical life were shown to be less than one in ten thousand. In 2001 those odds shrank to less than one in a number so large it might as well be infinity.
An account of scientific evidence in support of the anthropic principle fills several books. The authors’ religious beliefs run the gamut from agnosticism to deism to theism, but virtually every research astronomer alive today agrees that the universe manifests exquisite fine-tuning for life. Furthermore, this fine-tuning (Qua Variant) with our hardwired brain as created conditions our intellect in a manner that screams Creator, God, to the most meager intellect.
Please note that quantum mechanics states that any event with probability smaller than 10 to the -56 shall not happen; it’s out of reality. This presents another astonishing fact; the universe could not have come into existence randomly. There had to been an Independent agent outside of space and time who created us and the universe. Us Christians call this agent God.
