Something from Nothing?

I do not know if Lawrence Krauss typifies scientists in his logical obtuseness, but he certainly exemplifies the breed of so-called scientists who proclaim atheism as a scientific necessity.  According to a review by David Albert of Krauss’s recent book, A Universe from Nothing,

the laws of quantum mechanics have in them the makings of a thoroughly scientific and adamantly secular explanation of why there is something rather than nothing.

Albert’s review, which I have quoted extensively elsewhere, comports with Edward Feser’s analysis:

The bulk of the book is devoted to exploring how the energy present in otherwise empty space, together with the laws of physics, might have given rise to the universe as it exists today. This is at first treated as if it were highly relevant to the question of how the universe might have come from nothing—until Krauss acknowledges toward the end of the book that energy, space, and the laws of physics don’t really count as “nothing” after all. Then it is proposed that the laws of physics alone might do the trick—though these too, as he implicitly allows, don’t really count as “nothing” either.

Bill Vallicella puts it this way:

[N]o one can have any objection to a replacement of the old Leibniz question — Why is there something rather than nothing? … — with a physically tractable question, a question of interest to cosmologists and one amenable to a  physics solution. Unfortunately, in the paragraph above, Krauss provides two different replacement questions while stating, absurdly, that the second is a more succinct version of the first:

K1. How can a physical universe arise from an initial condition in which there are no particles, no space and perhaps no time?

K2. Why is there ‘stuff’ instead of empty space?

These are obviously distinct questions.  To answer the first one would have to provide an account of how the universe originated from nothing physical: no particles, no space, and “perhaps” no time.  The second question would be easier to answer because it presupposes the existence of space and does not demand that empty space be itself explained.

Clearly, the questions are distinct.  But Krauss conflates them. Indeed, he waffles between them, reverting to something like the first question after raising the second.  To ask why there is something physical as opposed to nothing physical is quite different from asking why there is physical “stuff” as opposed to empty space.

Several years ago, I explained the futility of attempting to decide the fundamental question of creation and its cause on scientific grounds:

Consider these three categories of knowledge (which long pre-date their use by Secretary of Defense Donald Rumsfeld): known knowns, know unknowns, and unknown unknowns. Here’s how that trichotomy might be applied to a specific aspect of scientific knowledge, namely, Earth’s rotation about the Sun:

1. Known knowns — Earth rotates about the Sun, in accordance with Einstein’s theory of general relativity.

2. Known unknowns — Earth, Sun, and the space between them comprise myriad quantum phenomena (e.g., matter and its interactions of matter in, on, and above the Earth and Sun; the transmission of light from Sun to Earth). We don’t know whether and how quantum phenomena influence Earth’s rotation about the Sun; that is, whether Einsteinian gravity is a partial explanation of a more complete theory of gravity that has been dubbed quantum gravity.

3. Unknown unknowns — Other things might influence Earth’s rotation about the Sun, but we don’t know what those other things are, if there are any.

For the sake of argument, suppose that scientists were as certain about the origin of the universe in the Big Bang as they are about the fact of Earth’s rotation about the Sun. Then, I would write:

1. Known knowns — The universe was created in the Big Bang, and the universe — in the large — has since been “unfolding” in accordance with Einsteinian relativity.

2. Known unknowns — The Big Bang can be thought of as a meta-quantum event, but we don’t know if that event was a manifestation of quantum gravity. (Nor do we know how quantum gravity might be implicated in the subsequent unfolding of the universe.)

3. Unknown unknowns — Other things might have caused the Big Bang, but we don’t know if there were such things or what those other things were — or are.

Thus — to a scientist qua scientist — God and Creation are unknown unknowns because, as unfalsifiable hypotheses, they lie outside the scope of scientific inquiry. Any scientist who pronounces, one way or the other, on the existence of God and the reality of Creation has — for the moment, at least — ceased to be scientist.

Which is not to say that the question of creation is immune to logical analysis; thus:

To say that the world as we know it is the product of chance — and that it may exist only because it is one of vastly many different (but unobservable) worlds resulting from chance — is merely to state a theoretical possibility. Further, it is a possibility that is beyond empirical proof or disproof; it is on a par with science fiction, not with science.

If the world as we know it — our universe — is not the product of chance, what is it? A reasonable answer is found in another post of mine, “Existence and Creation.” Here is the succinct version:

  1. In the material universe, cause precedes effect.
  2. Accordingly, the material universe cannot be self-made. It must have a “starting point,” but the “starting point” cannot be in or of the material universe.
  3. The existence of the universe therefore implies a separate, uncaused cause.

There is no reasonable basis — and certainly no empirical one — on which to prefer atheism to deism or theism. Strident atheists merely practice a “religion” of their own. They have neither logic nor science nor evidence on their side — and eons of belief against them.

Another blogger once said this about the final sentence of that quotation, which I lifted from another post of mine:

I would have to disagree with the last sentence. The problem is epistemology — how do we know what we know? Atheists, especially ‘scientistic’ atheists, take the position that the modern scientific methodology of observation, measurement, and extrapolation from observation and measurement, is sufficient to detect anything that Really Exists — and that the burden of proof is on those who propose that something Really Exists that cannot be reliably observed and measured; which is of course impossible within that mental framework. They have plenty of logic and science on their side, and their ‘evidence’ is the commonly-accepted maxim that it is impossible to prove a negative.

I agree that the problem of drawing conclusions about creation from science (as opposed to logic) is epistemological. The truth and nature of creation is an “unknown unknown” or, more accurately, an “unknowable unknown.” With regard to such questions, scientists do not have logic and science on their side when they asset that the existence of the universe is possible without a creator, as a matter of science (as Krauss does, for example). Moreover, it is scientists who are trying to prove a negative: that there is neither a creator nor the logical necessity of one.

“Something from nothing” is possible, but only if there is a creator who is not part of the “something” that is the proper subject of scientific exploration and explanation.

Probability, Existence, and Creation

A point that I make in “More about Probability and Existence” is made more eloquently and succinctly by Jacques Maritain:

To attempt to demonstrate that the world can be the effect of chance by beginning with the presupposition of this very possibility is to become the victim of a patent sophism or a gross illusion. In order to have the right to apply the calculus of probabilities to the case of the formation of the world, it would be necessary first to have established that the world can be the effect of chance. (Approaches to God, Macmillan paperback edition, pp. 60-1.)

To say that the world as we know it is the product of chance — and that it may exist only because it is one of vastly many different (but unobservable) worlds resulting from chance — is merely to state a theoretical possibility. Further, it is a possibility that is beyond empirical proof or disproof; it is on a par with science fiction, not with science.

If the world as we know it — our universe — is not the product of chance, what is it? A reasonable answer is found in another post of mine, “Existence and Creation.” Here is the succinct version:

  1. In the material universe, cause precedes effect.
  2. Accordingly, the material universe cannot be self-made. It must have a “starting point,” but the “starting point” cannot be in or of the material universe.
  3. The existence of the universe therefore implies a separate, uncaused cause.

There is no reasonable basis — and certainly no empirical one — on which to prefer atheism to deism or theism. Strident atheists merely practice a “religion” of their own. They have neither logic nor science nor evidence on their side — and eons of belief against them.

More about Probability and Existence

In “A Digression about Probability and Existence” I address

the view that there is life as we know it — an outcome with a low, prior probability given the (theoretical) multitude of possible configurations of the universe — only because there are vastly many actual or possible universes with vastly many configurations.

I observe that

[i]n this view, life as we know it is an improbable phenomenon that we are able to witness only because we happen to exist in one of the multitude of possible or actual universes.

I should have pointed out that it is impossible to know whether life as we know it is a low-probability event. Such a conclusion rests on an unsupportable assumption: the existence of a universe which is “fine tuned” to enable life is a low-probability event. And yet, that assumption is the basis for assertions that the existence of our universe — with its life-supporting combination of matter, energy, and physical laws — “proves” that there must be other universes because ours is so unlikely. Such “logic” is an edifice of rank circularity constructed on a foundation of pure supposition.

Such “logic,” moreover, misapplies the concept “probability.” No object or event has a probability (knowable chance of happening) unless it meets the following conditions:

1. The object or event is a member of a collective of observable phenomena, where every member of the collective has common features.

2. The collective is a mass phenomenon or an unlimited sequence of observations, where (a) the relative frequencies of particular attributes withing the collective tend to fixed limits and (b) these fixed limits remain the same for reasonably large subsets of the collective. (Adapted from “Summary of the Definition,” on pp. 28-9 in Chapter 1, “The Definition of Probability,” of Richard von Mises’s Probability, Statistics and Truth, 1957 Dover edition.)

Mises, obviously, was a  “frequentist,” and his view of probability is known as “frequentism.” Despite the criticisms of frequentism (follow the preceding link), it offers the only rigorous view of probability. Nor does it insist (as suggested at the link) that a probability is a precisely knowable or fixed value. But it is a quantifiable value, based on observations of actual objects or events.

Other approaches to probability are vague and subjective. There are, for example, degrees of belief (probabilistic logic), statements of propensity (probabilistic propensity), and “priors” (Bayesian probability). Unlike frequentism, these appeal to speculation, impressions, and preconceptions. Reliance on such notions of probability as evidence of the actual likelihood of an event is the quintessence of circularity.

In summary, there is no sound basis in logic or empirical science for the assertion that the universe we know is a highly improbable one and, therefore must be one of vastly many universes — if it was not the conscious creation of an exogenous force or being (i.e., God). The universe we know simply “is” — and that is all we know or probably can know, as a matter of science.

A Digression about Probability and Existence

The probability of an event can be the probability that it will (or could) happen, or the relative occurrence of the event as that occurrence is observed in nature or experiment.

It is known, for example, that the following prior probabilities attach to the outcome of a single roll of a pair of fair dice:

And if a single person rolled a pair of dice 1,000,000 times or 1,000,000 persons each rolled a pair of dice once, the result would be close (but not necessarily identical) to this:

But the fact that a single player, on a single roll, throws a 2, 5, 9, 12, or any other sum tells us nothing about the number of rolls the player has made or will make, nor does it tell us anything about the number of players who may have rolled dice at the same moment. All it tells us is that the player has attained a particular result on that particular roll of the dice.

This is at odds with the view that there is life as we know it — an outcome with a low, prior probability given the (theoretical) multitude of possible configurations of the universe — only because there are vastly many actual or possible universes with vastly many configurations. In this view, life as we know it is an improbable phenomenon that we are able to witness only because we happen to exist in one of the multitude of possible or actual universes.

So, is our universe and the life that has arisen in it a consequence of design, or is it all a matter of “luck”? And if it is due to “luck,” what created the material of which the universe is made and what determined the laws that are evident in the actions of that material?
