Stubborn Physical Limits
lTime – no more than 14 billion years are available, 4.42 x 1017 seconds.
lMatter – no more than 1080 baryons, i.e. 1080 nuclei or atoms, in our universe.
lProteins – thus, no more than 3.1 x 1091 proteins can have contributed to the naturalistic formation of life, less than 1081 in any one galaxy, less than 1050 on Earth.
lChances – no more than 1050 tries to bring about every step of naturalistic evolution on Earth.
