In part one, you’ll remember that I argued that the progress of science in confirming the big bang disproved atheism, and I on went to speculate about why there are still atheists today, given this tremendous scientific discovery. This time, I want to discuss the fine-tuning of the initial constants and conditions of the big bang and see how atheists responded to these recent scientific discoveries.
In nature, the values of physical constants, (e.g. – the force of gravity), are set at the instant when the universe is created. Initially, atheists assumed that the constants could be any value, and life would still exist. But the progress of science has shown that if these constants were altered even slightly, then the resulting universe would not permit life. For example, physicist Brandon Carter has shown that if the force of gravity were stronger or weaker by 1 part in 10 to the 40th power, life-sustaining stars could not exist. While each possible value of the force of gravity is equally unlikely, the vast majority of these possibilities prohibit complex life of any kind. That means that any one value picked at random is as likely as any of the others, but it is overwhelmingly likely that the one picked will not permit life.
And how do atheists respond to the evidence of a universe that is finely-tuned for life? Well, there are two responses I’ve seen. The first is to speculate that there are actually an infinite number of other universes that are not fine-tuned, (i.e. – the gambler’s fallacy). All these other universes don’t support life. But, lucky us, we just happen to be in the one universe that popped into being out of nothing, and is fine-tuned to an incredible degree for life. What’s that you say? “Wintery! How can we be sure that these other universes even exist?” Why, you just have to have faith, because there is no way of directly observing these other universes. So, to be an intellectually-fulfilled atheist, you have to believe in billions and billions of demons unobservable universes.
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 inconceivably vast multiverse. Most of those universes are barren, but some, like ours, have conditions suitable for life.
The idea is controversial. Critics say it doesn’t even qualify as a scientific theory because the existence of other universes cannot be proved or disproved. Advocates argue that, like it or not, the multiverse may well be the only viable nonreligious explanation for what is often called the “fine-tuning problem”—the baffling observation that the laws of the universe seem custom-tailored to favor the emergence of life.
The second response by atheists is that the human observers that exist today, 14 billion years after the universe was created out of nothing, actually caused the fine-tuning. Now you say to me, “Wintery! How can fairies humans fine-tune constants that were set before humans even existed!” Well, it’s true that causality in science has never been known to go backwards in time. But hey, atheists already believe that the entire physical universe popped into being out of nothing. What’s one more anti-science delusion to someone already against the law of conservation of mass and matter? I mean, if you’re already against the progress of science, why not double down?
…maybe we should approach cosmic fine-tuning not as a problem but as a clue. Perhaps it is evidence that we somehow endow the universe with certain features by the mere act of observation… observers are creating the universe and its entire history right now. If we in some sense create the universe, it is not surprising that the universe is well suited to us.
So what makes people become atheists? It isn’t arguments or evidence, because the progress of science repudiates atheism-of-the-gaps. Atheism is really just a long-running tempter tantrum. Atheism is caused when a child’s selfish autonomy runs into moral obligations, or when a child feels alienated because they are raised in a minority religion. The extreme reactions to these typical childhood experiences is triggered by the atheism-module of the brain. Scientists now believe that the atheism-module causes atheists to want to start wars, such as the wars of atheistic communism, which killed over 100 million people, and still enslaves millions in North Korea, Cuba, Zimbabwe, etc.
A podcast with scientist Scott Chambers, an active researcher on the fine-tuning is here. Here are two posts (first, second) discussing Newsweek’s evasions of the fine-tuning, (related podcast here). Five podcasts with atheist scholar Bradley Monton on cosmic fine-tuning are here. Physicist Robin Collins argues here that even if you take the blind leap-of-faith into multiverse-land, you still need a fine-tuning intelligence. Further discussions of the unobservable multiverse delusion are here and here. Further discussions of the non-existent observer delusion are here and here. For a serious, non-snarky, non-satirical look at the psychology of atheism, by a former atheist Professor of Psychology at New York University, look here, (related podcast).
