Cosmic Fine-Tuning Quotes

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.

Once we see, however, that the probability of life originating at random is so utterly minuscule as to make it absurd, it becomes sensible to think that the favorable properties of physics, on which life depends, are in every respect deliberate.... It is, therefore, almost inevitable that our own measure of intelligence must reflect higher intelligence -even to the limit of God.

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.

There are 15 constants- the gravitational constant, various constants about the strong and weak nuclear force, etc.- that have precise values. If any one of those constants was off by even one part in a million, or in some cases, by one part in a million million, the universe could not have actually come to the point where we see it. Matter would not have been able to coalesce, there would have been no galaxy, stars, planets or people

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.

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.

It is prima facie highly implausible that life as we know it is the result of a sequence of physical accidents together with the mechanism of natural selection.

In our universal experience unintelligent material processes do not create life

There are thousands of proteins in the cells, some of them very large chains of molecules. And the cell doesn't function if one of those chains of molecules isn't there, and you start looking at the complexity of life and the mystery of life, and then start thinking about things like the twenty universal constants, that if any one of them from Plank's minimum to the mass of a proton, if one of them is the tiniest bit off, there would be no life or possibility of it in the universe.

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.

It is quite true that many scientists, many physicists, maintain that the physical constants, the half dozen or so numbers that physicists have to simply assume in order to derive the rest of their understanding ... have to be assumed. You can't provide a rationale for why those numbers are there. Physicists have calculated that if any of these numbers was a little bit different, the universe as we know it wouldn't exist.

The anthropic principle is an unfortunate name as it implies something about humanity.

...things are the way they are in our universe because if they weren't, we wouldn't be here to notice.

To get our universe, with all of its potential for complexities or any kind of potential for any kind of life-form, everything has to be precisely defined on this knife edge of improbability. [Y]ou have to see the hands of a creator who set the parameters to be just so because the creator was interested in something a little more complicated than random particles.

It is prima facie highly implausible that life as we know it is the result of a sequence of physical accidents together with the mechanism of natural selection. We are supposed to abandon this naïve response, not in favor of a fully worked out physical/chemical explanation but in favor of an alternative that is really a schema for explanation, supported by some examples. What is lacking, to my knowledge, is a credible argument that the story has a nonnegligible probability of being true.
