Fine-tuned universe

Also, the fine-tuning of the Universe is the apparent delicate balance of conditions necessary for human life. In this view, speculation about a vast range of possible conditions in which life cannot exist is used to explore the probability of conditions in which life can and does exist. For example, it can be argued that if the force of the Big Bang explosion had been different by 1/10 to the sixtieth power or the strong interaction force was only 5% different, life would be impossible. Noted physicist Stephen Hawking estimates that "if the rate of the universe's expansion one second after the Big Bang had been smaller by even one part in a hundred thousand million million, the universe would have re-collapsed into a hot fireball due to gravitational attraction". In terms of a teleological argument, the intuition in relation to a fine-tuned universe would be that God must have been responsible, if achieving such perfect conditions is so improbable. However, in regard to fine-tuning, Kenneth Einar Himma writes: "The mere fact that it is enormously improbable that an event occurred... by itself, gives us no reason to think that it occurred by design... As intuitively tempting as it may be..." Himma attributes the "Argument from Suspicious Improbabilities", a formalization of "the fine-tuning intuition" to George N. Schlesinger:
