We now know that many other constants of physics also exhibit fine tuning as a condition of a life-permitting universe.36 The electromagnetic force constant exhibits moderate fine tuning of 1 part in 25.37 The strong nuclear force constant is fine-tuned to 1 part in 200.38 Moreover, the ratios of the values of the different force constants also require significant fine tuning. For example, the ratio of the weak nuclear force constant to the strong nuclear force constant had to have been set with a precision of 1 part in 10,000.39 If the weak force had been weaker or stronger by that small
