"In some strange sense, it appears that we are not adapted to the universe; the universe is adapted to us ... Short of invoking a benevolent creator, many physicists see only one possible explanation: Our universe may be but one of perhaps infinitely many universes in an inconceivable vast multiverse ... Critics say it doesn't even qualify as a scientific theory because the existence of other universes cannot be proved or disproved ... 'If there is only one universe,' Carr says, 'you might have to have a fine-tuner. If you don't want God, you'd better have a multiverse.'"
