9.3 Fine Tuning and The Weak Anthropic Principle<br />

“The observed values of all physical and cosmological quantities<br />

are not equally probable, but they take on values restricted by<br />

the requirement that there exist sites where carbon-based life<br />

can evolve and by the requirement that the Universe be old<br />

enough for it to have already done so. “<br />

Barrow, John and Tipler, Frank (1986): The Anthropic<br />

Cosmological Principle. Clarendon Press.<br />

Statistically, the chance for obtaining a definite macro-world out<br />

of the quantum realm is practically zero, and so is the chance for<br />

setting up the initial condition of the Big Bang to match the<br />

Universe we live in -- the accuracy of pinpointing our Universe is<br />

the Human Mind. Cambridge: Cambridge University Press.).<br />

"The remarkable fact is that the values of these numbers (i.e. the<br />

constants of physics) seem to have been very finely adjusted to<br />

make possible the development of life". "For example," Hawking<br />

writes, "if the electric charge of the electron had been only<br />

slightly different, stars would have been unable to burn hydrogen<br />

and helium, or else they would not have exploded. It seems clear<br />

that there are relatively few ranges of values for the numbers (for<br />

the constants) that would allow for development of any form of<br />

intelligent life. Most sets of values would give rise to universes<br />

that, although they might be very beautiful, would contain no one<br />
