An Introduction to Scientific
Cosmology
This session of our series will focus on the
intriguing religious questions raised by modern scientific discoveries concerning the
origins of the universe. The last one hundred years of the study of the universe have
yielded a number of important discoveries that have provoked questions among scientists
that reflect religious concerns among some of the scientific community. It is the task of
this session to explore some of these discoveries and their possible relevance for a
religious understanding of the world.
On Christmas Eve 1968, the first astronauts in orbit around
the moon appeared live on TV in millions of American homes. Frank Borman read the opening
verses of Genesis:
In the beginning God created the
heavens and the earth. The earth was without form and void, and darkness was upon the face
of the deep: and the Spirit of God was moving over the face of the water. And God said,
"Let there be light", and there was light.
Bormans message concluded: "Greetings
from the crew of Apollo 8. God bless you all on the good earth." Those
astronauts were the first people to see the beauty of the earth as a blue and white gem
spinning in the vastness of space, and the reading from Genesis story be reconciled with
the findings of twentieth-century astronomy? 1
Introduction
In the early part of the twentieth century (1929) Karl
Hubble was looking through his telescope and noticed something rather peculiar happening
in space. He began to make a study of what he was seeing and came to the conclusion that
the galaxies in space are moving away from each other at about one million miles per hour.
He sent his findings to Albert Einstein, who at first rejected his findings. However,
Hubble would not be dissuaded from the findings of his study. He invited Einstein to meet
with him and to see for himself. Einstein did just that and upon observation and
discussion with Hubble concurred with the findings. This implication of the meaning of
these finding was and is momentous. Such findings confirm the theory that we live in an
expanding universe set into motion by the "Big Bang" that occurred about fifteen
billion years ago. Whats more, time and space also began with the "Big
Bang" so that space is expanding! Such a finding revealed that we live in a dynamic,
changing and yet stabilizing universe. There is continuity and predictability, as well as
novelty and spontaneous creation.
For many years scientists argued whether or not we live in
an expanding or "steady-state" universe. The steady-state universe always
existed, no beginning and no end. Such a scientific position would maintain that no
creation was necessary. But in 1965 two scientists from Bell Laboratories named Penzias
and Wilson discovered a uniform hiss of radiation that is uniform in every part of the
universe which is evidence of the "Big Bang" that occurred some fifteen billion
years ago. This was one of many other discoveries that suggest that our universe had a
moment of creation.
The religious implications of the "Big Bang"
provoked questions from some members of the scientific community. Who or what is
responsible for the "Big Bang"? The notion of a Creator, or intelligence behind
the creation of the universe began to impose itself on the scientific community, as a
result of a series of discoveries that seemed to suggest the intelligent design of the
universe. As time has passed scientists have discovered that there are a balance of forces
in the universe that are so fine that any variation would have meant a very different type
of universeor none at all! In the words of Stephen Hawking:
If the rate of expansion one
second after the Big Bang had been smaller by even one part in a hundred thousand million
million it would have recollapsed before it reached its present size.1
With these new discoveries a number of cosmologists have
proposed a theory known as the anthropic cosmological principle. The anthropic
principle is one that states that there is a design to the universe that has life,
especially human life, as a part of its plan written into creation by the Creator. This
theory has two variations: the strong anthropic principle and the weak anthropic
principle. 2
The strong anthropic principle maintains that the universe
was created for the emergence of mind and especially the spiritual and self-reflective
creatureshumanity. In this version of the anthropic principle all creation was
designed for the emergence of those created in the image of God.
The weak anthropic principle maintains that conditions in
the universe are just right for the emergence of life and human life. It does not hold
that all creation was designed specifically for the emergence of human life but that such
an emergence was written into the universe as a distinct and probable possibility.
The argument for Gods existence from
"design" has witnessed resurgence not so much from theologians but from some
scientists. Recent discoveries have provoked philosophical and religious questions among
scientists. The new argument from design have emerged as a result of the discovery that
even small changes in the physical properties and constants in the universe would have
resulted in an uninhabitable universeas suggested by Dr. Steven Hawking when he
described the rate of expansion.3
There are other intriguing aspects of the universe as well.
For instance, if the strong nuclear force were even slightly weaker we would have only
hydrogen in the universe. If it were slightly stronger, all the hydrogen would have been
converted to helium.
In either case, stable stars and
compounds such as water could not have been formed. Again, the nuclear force is only
barely sufficient for carbon to form; yet if it had been slightly stronger, the carbon
would all have been converted to oxygen. Particular elements, such as carbon have many
other special properties that are crucial to the later development of organic life as we
know it.4
Another extraordinary condition of the universe is the
"particle/anti-particle ratio". That is, for every billion antiprotons in the
early universe, there were one billion one protons. The billion pairs annihilated each
other to produce radiation, with just one proton left over. A greater or smaller number of
survivorsor none at all would have made our universe impossible. Such discoveries
have provoked a number of scientists to point to some religious implications to the
universe.
The odds against a universe like
ours emerging out of something like the Big Bang are enormous. I think there are clearly
religious implication. 5
The physicist Freeman Dyson writes:
The Argument from Design, gives a
number of examples of "numerical accidents" that seem to conspire to make the
universe habitable
The more I examine the universe and the details of its
architecture, the more evidence I find that the universe is some sense must have known we
were coming. 6
Some Theological Implications
It is necessary to state before exploring the theological
implications of modern cosmology that God is not to be understood as a mere explanation
for creation or as One who fill the gaps in the human understanding, i.e., "the God
of the gaps". God is not to be used to fill in the things that human reason has not
discovered about the universe. This being said, we will deal with the theological
implications of modern cosmology under four headings suggested by Ian Barbour which are as
follows.
Intelligibility and Contingency
Ex Nihilo and Continuing Creation
The Significance of Humanity
Eschatology and the Future
Intelligibility and Contingency
The scientific search for a Grand Unified Theory (GUT) for
the universe is partly motivated by the conviction that the cosmos is rationally
intelligible, Einstein once stated that the only thing that incomprehensible about the
world id that it is comprehensible.6 The Greek view of the world as cosmos and not chaos
combined with the biblical view if the universe as rational and contingent. If God is the
source of reason, the world is orderly; but if God is also free, then the world did not
have to have the particular order that it has. Furthermore, such a God makes possible the
reality of novelty and spontaneous creation that we see reflected in the theory of quantum
mechanics. In our universe there exists dependability and novelty. The physicist James
Trefil sees it this way:
But who
created those laws?
Who made the laws of logic?
No matter how far the boundaries
are pushed back, there will always be room for both religious faith and a religious
interpretation of the physical world. For myself, I feel much more comfortable with the
concept of God who is clever enough to devise the laws of physics that make the existence
of our marvelous universe inevitable than I do with the old-fashioned God who had to make
it all, laboriously, piece by piece.7
Such a view of creation understands the first creation
account of Genesis 1:1-29 as a story recognizing God as creator, the order and the basic
goodness of creation, and humanity at the pinnacle of creation. Such did not happen in six
solar days but over aeons of time. To read the Genesis text in any other fashion is to
impose a literal meaning that was not intended. 8
Contingent Existence
The concern about the contingency of the universe is best
captured by the question: "why is there anything at all?" The existence of the
universe, of anything, is the most surprising of all things that provokes an explanation.
The existence of the cosmos as a
whole is not self-explanatory, regardless of whether it is finite or infinite in time.
9
Such a fundamental fact of the existence of the universe
quickly moved to why anything exists at all. Furthermore, if there was a beginning, it was
a "singularity" to which the laws of physics do not apply. That is, we cannot
get behind the Big Bang. All of the clues were destroyed in the primal explosion. What we
have as a universe is the effect of that explosion. What' more, we know that we live
in a universe of order and uncertainty. The indeterminacy in the world reflected in
quantum physics tells us new things can occur. Also, we know that there is an irreversible
character to event and time. So we are left with the fact that the universe need not have
been and still is unfolding. What or "Who" set things in motion provokes
questions outside of sciences ability to answer them. 10
The Significance of Humanity
Upon initial observation of the immensity of the universe
one would be tempted to conclude that in the large scope of things humanity occupies a
very small and insignificant place in the universe. Certainly, one can be humbles by such
an observation, but one must exercise some caution in taking such a view to the extreme.
Protestant theologian, Sally McFague refers to such an extreme attitude toward humanity as
a form of decadent asceticism. Such a view undermines human dignity and human stewardship
for one another and the world. Telling people they are worthless or insignificant does not
serve the purpose of creating a sense of humility but in seeing human life as not worth
much.
Today the immensities of time and space seem to favor the
notion that the universe we live in was waiting for us. For instance, it is known that it
takes about fifteen billion years for heavy elements to be cooked in the interior of stars
and eventually for the evolution of consciousness. Fr. Teilhard de Chardin pointed out
that we should not measure significance by size and duration, but by such criteria as
complexity and consciousness. It is clear that a higher level or organization and a
greater richness of experience occur in a human being than in a thousand lifeless
galaxies. It is humanity itself that reaches out to understand, and seems capable of
understanding itself and the universe.
Eschatology and the Future
For the scientist the future of the universe and the
individual are profoundly connected. One theory holds that the expansion of the universe
will continue until the universe runs down so that the universe experiences heat death.
Another theory holds that the universe will continue to expand until it reaches a point
when it begins to slow down, and stop. Eventually the force of gravity with caused the
universe to slow down and stop will begin to cause the universe to contractin which
case the universe will suffer from the "Big Crunch". Or we might put it into the
words of scientist Steven Weinberg when he says, "It going to get pretty
unpleasant."
Such forecasts for the universe would lead to the eventual
demise of all lifea view of things that could easily lead to despair. The Christian
view is that God is involved with the universe through its laws and properties and is
working to bring it to a glorious consummation (Romans 8). 12 Such a view is consistent
with St. Pauls understanding of the resurrection of Jesus and the future of humanity
and the rest of creation (I. Cor. 15) In this case the universe is filled with meaning and
a cause of joy and hope.
