Science and Creation: A Kabbalistic Approach
Modern cosmology meets traditional Jewish mysticism.

Modern
cosmology--the scientific study of the universe as a whole--no longer sees the
universe as an infinite changeless arena in which events take place, the way
Isaac Newton did. The universe is an evolving, expanding being, and its origin
is the oldest mystery.
For the first
time in possibly a million years of human wondering, we are not simply
imagining the beginning: We are observing it, in radiation that has been
traveling to us since the Big Bang, possibly bearing information generated even
earlier. Theorists are piecing the data together into humanity's first
verifiable creation story.
Most educated
people today have an essentially Newtonian picture of the universe as a place,
devoid of all human meaning, in which we happen to find ourselves. If people
come to understand the emerging scientific cosmology, however, they may see
from what we know of the early universe that we actually are part of an
extraordinary adventure. With its mind-expanding imagery, this emerging
cosmology gives us a new cosmic perspective, a powerful source of awe, and a
potential source of meaning in our everyday lives.
Expansion of the Universe
In 1929, Edwin
Hubble discovered the expansion of the universe by showing that the more
distant a galaxy is from us, the faster it is moving away. Astrophysicists ran
the movie backward and realized that the universe had to have started out
extremely hot and dense.
The earliest
point was named--derisively by astronomer and novelist Fred Hoyle, whose steady
state theory it eventually replaced--the "Big Bang." Standard Big
Bang theory explains the creation of the light elements of matter in the first
three minutes and seems to be right as far as it goes, but it does not explain
what preceded that or what has followed.
Gravity alone
could not have created the complex large-scale structures and flows of galaxies
that are observed to exist. Gravity magnifies differences--that is, if one
region is ever so slightly denser than average, it will expand a bit more
slowly and grow relatively denser than its surroundings, while regions with
less than average density will become increasingly less dense. But if matter
after the Big Bang was absolutely evenly distributed, gravity would have done
nothing but slow down the overall expansion.
Consequently,
either some unknown force acting after the Big Bang formed the giant structures
we observe today--which looks increasingly dubious else gravity must have had
some differences in density to work with from the beginning. What could have
caused these differences in density? Big Bang theory is silent about its own
initial conditions.
Exponential Growth
The theory of
inflation, proposed in the early 1980s by Alan Guth and others, says that for
an extremely small fraction of a second before the Big Bang--much less time
than it would take light to cross the nucleus of an atom--the universe expanded
exponentially, inflating countless random quantum events in the process.
The density
differences in the universe reflect these quantum events, enormously inflated.
This is the best theory cosmologists have for the origin of the needed density
differences. Inflation is exponential growth--the longer it goes on, the faster
it gets.
Kabbalah: A Parallel Theory
Kabbalah,
medieval Jewish mysticism, is the only traditional cosmology we know of in
which the universe was understood to have begun in a point and expanded. We are
not kabbalists, nor are we trying to promote Kabbalah. We are not arguing that
Kabbalah was prescient, or that the kabbalists somehow knew mystically what
science is now discovering.
We are
interested in Kabbalah because it developed a set of ideas describing the
origin of an expanding universe and integrated these ideas into its religious
worldview. Can Kabbalah help us to integrate the scientific concepts we have
been describing into our own culture?
Kabbalah is an
example of a cosmology resembling our own which successfully penetrated and
enriched the lives of a society. In the sixteenth century, the great kabbalist
Isaac Luria developed the scheme further, teaching that in the beginning, God
began to withdraw into self-exile in order to make space for the universe.
Repairing the World
God envelopes
the universe, in the Lurianic way, but when God withdrew, evil became possible
inside. God sent holy light into the world, but the world was too weak to hold
God's glory. Its cornerstones were vessels that shattered in the light. The
role of the Jews is to repair the shattered vessels by re-collecting the sparks
of God in the world.
Tzimtzum is the name of God's self-exile. Tikkun olam is the repairing of the
world. For Jews in the century or so after the expulsion from Spain in 1492,
the concept of a God in exile gave cosmic meaning to their people's traumatic
and seemingly endless history of expulsions and exiles. The cosmology alone,
however, did not provide the meaning. It came from the circumstances of their
lives and their era, but it was expressible at a deep and satisfying level with
the help of their kabbalistic cosmological myth. Can the same become true with
modern cosmology?
Kabbalah was a
cultural outgrowth of medieval European Jewish experience. By the time of the
European Enlightenment, Jews who read Descartes and Newton considered the idea
of sefirot [divine emanations] as
absurd as angels dancing on the head of a pin. But Kabbalah is a metaphorical
description of a set of fundamental universal relationships which in light of
modern astrophysics appears closer to reality than the infinite rectangular
space of the Newtonian worldview.
The Search for a Functional Modern Cosmology
We do not argue
that either kabbalistic cosmology or current scientific theories about the
origin is "true" in some ultimate sense, but rather that by seeing
each in light of the other, we begin to get some sense of what to demand of any
cosmology intended to function for human society in the 21st century. Just
as light cannot be described accurately as either a particle or a wave but only
as something beyond either metaphor, the universe cannot be adequately
described as either something scientifically observed or something spiritually
experienced. A functional cosmology must do both.
The reason
kabbalistic terms are helpful to our account is that they bind together the
search for truth with the search for the divine. If terms such as hokhmah [wisdom, one of the sefirot] did
not already exist bearing religious significance, we would have had to try to
coin them--which would probably have been as successful as Esperanto. The
emerging scientific cosmology and Kabbalah are two metaphor systems whose
juxtaposition points toward a truth larger than either can express alone.
The theory of
eternal inflation, whether or not it turns out to be true, has opened a cosmic
perspective on reality and the countless threads of connection, including the
spiritual, weaving through. If eternal inflation theory eventually turns out to
be wrong, whatever replaces it cannot explain less and will have to do better.
A new standard has been set for creation stories.
Vast Implications
If the theory of
eternal inflation is correct, then there is an eternal blizzard of universes,
in which our bubble is a single snowflake, an infinitesimal capsule of eternal
potential, crystallized into unique patterns of matter and energy, which has
set off from eternal inflation on its journey to realize itself in a universe.
No one has
thought of a way yet to test whether eternal inflation theory is right, but the
expansion of perspective the theory requires certainly enlarges our idea of the
physical universe. It may also enlarge our ideas of God, because regardless of
how much reality one may ascribe to God, one can only speak metaphorically, and
most metaphors are limited to the extremely narrow experience of Earth. This
does not make them wrong, but they are certainly limiting.
Cosmology
provides utterly different metaphors--eternal inflation, endless creation from
every sparkpoint--that humans could not have dreamed up had theoretical physics
not led them there. It seems to be a general rule that the more metaphor
systems through which we try to understand non-human-scale realities, both
large and small, the closer we come to truth.
Creating a Balance
In our
kabbalistic creation myth, tzimtzum--the withdrawal of God--occurred in eternal
inflation. As the notion of a God in exile gave cosmic meaning to the lives of
a people in exile, understanding cosmic inflation may give a new, if sobering,
meaning to the lives of a people dependent upon inflationary growth. Inflation
is a taste of what it is like to be God. It cannot be considered a normal human
pace. In a finite environment, inflation cannot continue, however cleverly we
may postpone or disguise the inevitable. This is a consequence of natural
laws.
The question for
our time is, how can we end inflation gently on Earth? How can we slow human
inflation enough that creative restoration can overtake it? When we have
developed a sustainable relationship with our planet, humanity and Earth will
be in balance, and the transition from inflation to stable expansion will have
been achieved through the restoration of the world--tikkun olam.
