Anthropic Principle Quotes

The laws of science, as we know them at present, contain many fundamental numbers, like the size of the electric charge of the electron and the ratio of the masses of the proton and the electron .... The remarkable fact is that the values of these numbers seem to have been finely adjusted to make possible the development of life.

The universe is specifically tweaked to enable life on earth-a planet with scores of improbable and interdependent life-supporting conditions that make it a tiny oasis in a vast and hostile universe.

Some physicists solve that problem of the necessity of finely tuned physical constants ... by invoking the anthropic principle, saying, well, here we are, we exist, we have to be in the kind of universe capable of giving rise to us. That in itself is, I think, unsatisfying, and as John Lennox rightly says, some physicists solve that by the multiverse idea-the idea that our universe is just one of many universes.

We shouldn't be surprised that conditions in the universe are suitable for life, but this is not evidence that the universe was designed to allow for life. We could call order by the name of God, but it would be an impersonal God. There's not much personal about the laws of physics.

Scientists are slowly waking up to an inconvenient truth - the universe looks suspiciously like a fix. The issue concerns the very laws of nature themselves.

Traditional arguments for the existence of God and contemporary attempts to use fine-tuning and cosmology to back up the case for his existence always strike me as kinds of games, since hardly anyone believes on the basis of these arguments at all.

The question not many ask is: why are the laws of physics like they are?

Someone once said that if you sat a million monkeys at a million typewriters for a million years, one of them would eventually type out all of Hamlet by chance. But when we find the text of Hamlet, we don't wonder whether it came from chance and monkeys. Why then does the atheist use that incredibly improbable explanation for the universe? Clearly, because it is his only chance of remaining an atheist. At this point we need a psychological explanation of the atheist rather than a logical explanation of the universe.

In fact, if one considers the possible constants and laws that could have emerged, the odds against a universe that produced life like ours are immense.

If gravity were somewhat stronger or weaker, stars wouldn't exist, and neither would you. And the same can be said of other constants of physics. Several have to be 'just right.'

Imagine a puddle waking up one morning and thinking, " This is an interesting world I find myself in, an interesting hole I find myself in; fits me rather neatly, doesn't it? In fact it fits me staggeringly well! It must have been made to have me in it!

To say that Nature displays intelligence doesn't make you a Christian fundamentalist. Einstein said as much, and a fascinating theory called the anthropic principle has been seriously considered by Stephen Hawking, among others.

The gravitational constant, if it were off by one part in a hundred million million, then the expansion of the universe after the Big Bang would not have occurred in the fashion that was necessary for life to occur. When you look at that evidence, it is very difficult to adopt the view that this was just chance.

I don't think about a theory of everything when I do my research. And even if we knew the ultimate underlying theory, how are you going to explain the fact that we're sitting here? Solving string theory won't tell us how humanity was born.

When you buy a jacket, you pick the size to ensure it fits. Similarly, we live in a universe in which the amount of dark energy fits our biological make-up. If the amount of dark energy were substantially different from what we've measured, the environmental conditions would be inhospitable to our form of life.

The Goldilocks Enigma is the idea that everything in the universe is just right for life, like the porridge in the fairy tale.

We see the universe the way it is because we exist.

As we look out into the Universe and identify the many accidents of physics and astronomy that have worked together to our benefit, it almost seems as if the Universe must in some sense have known that we were coming.

The other way is the multiverse way. That says that maybe the universe we are in is one of a very large number of universes. The vast majority will not contain life because they have the wrong gravitational constant or the wrong this constant or that constant. But as the number of universes climbs, the odds mount that a tiny minority of universes will have the right fine-tuning.

It's natural to think that living things must be the handiwork of a designer. But it was also natural to think that the sun went around the earth. Overcoming naive impressions to figure out how things really work is one of humanity's highest callings.

Only a very few would allow creatures like us to exist. Thus our presence selects out from this vast array only those universes that are compatible with our existence. Although we are puny and insignificant on the scale of the cosmos, this makes us in a sense the lords of creation.

It seems hopelessly improbable that any particular rules accidentally led to the miracle of intelligent life. Nevertheless, this is exactly what most physicists have believed: intelligent life is a purely serendipitous consequence of physical principles that have nothing to do with our own existence.

The intelligent beings in these regions should therefore not be surprised if they observe that their locality in the universe satisfies the conditions that are necessary for their existence. It is a bit like a rich person living in a wealthy neighborhood not seeing any poverty.

All of creation, in the biblical view, was to ultimately prepare the way for the creation of man. But one does not need the Bible alone to hold this view. A purely scientific reading of the universe is in keeping with this view. Everything - every natural and physical law - is exquisitely tuned to produce life, and ultimately man, on earth.

The evidence in this universe for design - or, if you will, the fine-tuning that cannot be explained by chance or by 'enough time' - is so compelling that the only way around it is to suggest that our universe is only one of an infinite number of universes.
