"45. Stability Of Protons -- This affects the quantity of matter in the universe and also the radiation level as it pertains to higher life forms. Each proton contains 3 quarks. Through the agency of other particles (called bosons) quarks decay into antiquarks, pions, and positive electrons. Currently in our universe this decay process occurs on the average of only once per proton per 10 to 32nd power years. If that rate were greater, the biological consequences for large animals would be catastrophic, for the proton decays would deliver lethal doses of radiation. If the proton were more stable, less matter would have emerged from events occurring in the first split second of the universe's existence. There would be insufficient matter in the universe for life to be possible."

"43. Dirac And Dicke's Coincidences -- In 1961, noted American physicist Robert Dicke noticed that life in the universe is possible only because of the special relationship among certain cosmological parameters (relationships researched by British physicist Paul dirac 24 years earlier). Dirac noted that the number of baryons (protons plus neutrons) in the universe is the square of the gravitational constant as well as the square of the age of the universe (both expressed as dimensionless numbers). Dicke discerned that a slight change in either of these relationships and life could not exist. Stars of the right type for sustaining life supportable planets only can occur during a certain range of ages for the universe. Similarly, stars of the right type only can form for a narrow range of values of the gravitational constant."

Anybody know anything about these?
