The fine-tuning argument argues that when physics and the laws of nature are expressed mathematically their values are ever so balanced in a way that permits the existence of life. I’m merely arguing that the universe is finely tuned for the essential building blocks and environments that life requires.
- Given the fine-tuning evidence, a life permitting universe (LPU) is very, very unlikely under the non-existence of a fine-tuner (~FT): that is, P(LPU|~FT & k) ≪ 1.
- Given the fine-tuning evidence, LPU is not unlikely under FT (Fine-Tuner): that is, ~P(LPU|FT & k) ≪ 1.
- Therefore, LPU strongly supports FT over ~FT.
Defense of 1: Given the fine-tuning evidence, a life-permitting universe is very, very unlikely under the non-existence of a fine-tuner.
So what are some of the evidences for fine-tuning?
- Roger Penrose calculates that the odds of the special low entropy condition having come about by chance in the absence of any constraining principles is at least as small as about one in 1010^123.
- Strong Nuclear Force (Strong nuclear force coupling constant, gs = 15)
- +, No hydrogen, an essential element of life
- -, Only hydrogen
