IS BIG BANG BIBLICAL?

INTRODUCTION
The question of Origins is the most foundational issue
facing mankind
today. The reason is that if random events are responsible
for human
existence, then the following three things are true:
1. We have no purpose beyond this life
2. We are accountable to no authority higher
than ourselves
3. We can do anything we want without eternal
consequences
Conversely if man is the Creation of a loving,
personal God, then:
1. There is purpose to our life
2. We are accountable to our Creator
3. Eternal consequences attend all of our
words and deeds
The first invites unbridled self-expression. The second
demands
surrendered self-control. Part 1 of TWO WORLD VIEWS highlights
these
views as Materialism and Theism, whereas Parts 3, 4 and
5 present
empirical evidence that originated within, and that is
accepted by
the scientific community. The evidence is shown to be
consistent with
Biblical Revelation, and to point to the following conclusion:
All that we see, and all that we are originated from a
Supreme
Intelligence of unfathomable domain and dimension.
This evidence falls into the following three categories:
1. OUR WORLD'S ADVENT
2. EXISTENCE OF LIFE
3. CENTRALITY OF MAN
OUR WORLD'S ADVENT
The evidence applicable to the advent of our universe comes
from the
fields of Cosmology, Astrophysics and Astronomy, and is
embodied in
conclusions that were forced by the measurements obtained
in these
disciplines. These measurements were guided by a theory
popularly
known as "The Big Bang"-- a term that arose from the sarcastic
remark
of Sir Fred Hoyle. At the time Hoyle was an atheist who
knew full
well the theological implications if the universe had
a beginning.
Ironically many Christians regard Big Bang with disdain,
either
because they do not understand it, or because they read
more than it
says into it. In this sense Big Bang is like an airplane.
It can be
used to drop bombs or medicine. Sadly, many Christians
use it to drop
bombs. Why do I say sadly? For two reasons: First, because
an
abundant amount of empirical evidence indicates that Big
Bang is
true. Secondly, because when properly understood, Big
Bang
underscores the veracity of Genesis 1, and it also affirms
the
existence of God.
BIG BANG ACCEPTANCE
Big Bang is accepted by virtually all astrophysicists and
cosmologists. Moreover, the last two decades have seen
a significant
increase in both the quality and the quantity of data,
and it has
served to raise our confidence in this conclusion.
This is not to say that all our questions have have been
answered.
Two of the most pressing questions surround the genesis
of galaxies,
and the nature of dark matter. But even so, answers are
emerging.
Nor is it to suggest that all scientists accept Big Bang.
But the
unanswered questions that remain do not falsify the many
otherwise
successful outcomes from the theory. Science often works
through
consensus, and the vast majority of scientists believe
that Big Bang
is true. Indeed, among those who work in the field, this
acceptance
is almost unanimous. This does not mean that Big Bang
is true. But it
does mean that there is a near unanimous belief that the
available
evidence points in this direction.
HISTORICAL CONTEXT
Why do so many astrophysicists and cosmologists believe
that Big Bang
is true? The answer goes back to 1927 when Edwin Hubble
observed that
the galaxies were moving away from one another at a speed
that was
proportional to the distance between them. To explain
what he saw, he
postulated that our world had exploded into existence
at some point
in the past. This was a radical departure from what had
been a common
understanding among scientists that the universe was "steady-state"
i.e., that it had always existed eternally.
The basis for this older belief rested in the First Law
of Science
(thermodynamics), which asserts that a natural process
cannot bring
into existence something from nothing. Since something
was in
existence (our universe), and since a natural process
could not have
created it from nothing, the only conclusion possible
from natural
law was that our universe had no beginning. Therefore
it was believed
to be eternally existing.
EVIDENCE OF AGE
But Hubble's postulate was a radical departure from steady-state,
and
soon scientists began to ask, "If the universe had a beginning,
how
long ago did it happen?" This question has been asked
many times
over, and from at least five vantage points. These are
(1) Globular
Clusters, (2) White Dwarf Cooling, (3) Doppler Redshift,
(4) Speed of
Light, and (5) Radio Isotopes. Let me give a brief description
of
each, and then explain why I have chosen to do so.
GLOBULAR CLUSTERS is a name given to collections of stars
whose
brightness and surface temperature, when plotted, "cluster"
along a
line called a "main sequence". Their point of departure
from the line
is a measure of the age of the stars.
WHITE DWARF COOLING measures age by applying thermodynamic
laws to
the rates at which "white dwarf" stars are observed to
cool. These
laws govern the rate at which radiation leaves these thermal
bodies,
and therefore the time period over which they can cool.
DOPPLER REDSHIFT is the change in color of the electromagnetic
radiation from stars and galaxies. These objects are "pinned"
to the
expanding fabric of "space-time." The expansion creates
a shift in
wavelength toward the red end of the spectrum that is
used to measure
age.
The SPEED OF LIGHT in vacuum is accepted as a universal
constant.
Triangulation is used to estimate distances which, in
conjunction
with the speed of light are used to measure age. Some
have tried to
suggest that light moved faster in the past. But at least
three
reasons argue against this: (1) Large experimental errors
attended
the earlier measurements, and the effect disappeared as
the errors
vanished; (2) Light's invariant speed produced Special
Relativity
and, with it, atomic bombs that explode; (3) Age measurements
obtained by this method agree with the other age measurements.
RADIO ISOTOPES consist of naturally occurring radioactive
elements
such as Uranium, Potassium and Thorium. Their decay rates
can be
described mathematically and used to measure their age.
Tens of
thousands of measurements made over nearly one-hundred
years show
that the method works, and that is a reliable tool.
Each of these measurements rests upon assumptions, and
these have
been carefully examined and weighed by the scientific
community.
Errors attend all measurements, and these "nucleochronometers"
are no
exception. But-- and here's the important but: Any one
of these age
estimates is independent of the other four, yet ALL give
an age for
our universe that lies between about 12 and 18 billion
years.
There are two important points to consider:
(1)
Each of five independent measurements indicate that
our universe came into existence billions of years ago
(not thousands or millions)
(2)
The age measurement is for our universe, NOT man,
NOT planet Earth, and NOT the life it contains
EVIDENCE OF BIG BANG - Einstein's Relativity
These age measurements enabled scientists to calculate
a hypothetical
point from which the "space-time" expansion appears to
have
originated. Conceptually, this "point" agrees with a mathematical
curiosity (called a "singularity") that appears in Einstein's
equations.
Einstein published Special Relativity in 1905 and General
Relativity
in 1916. The former predicted atom bombs, and the latter
the bending
of starlight by gravity-- first measured by Arthur Eddington
during a
total solar eclipse in 1919, and recently by scientists
tracking the
changing positions of quasars near the edge of the visible
universe.
Special Relativity also predicted time dilation-- confirmed
when
physicists measured minute emission variations of both
radioactive
iron nuclei between ground and on top a tall tower, and
also between
twin Cesium 137 atomic clocks, one that was kept at an
airport, while
the other flew around the world in an airliner.
Einstein's General Relativity provides the theoretical
framework for
Big Bang. For example, it predicted matter condensed into
25%
Hydrogen and Helium immediately after Big Bang-- confirmed
by later
studies of gas clouds and old stars. It also predicted
photon
radiation would cool to about 3 degrees Kelvin. Arno Penzas
and Bob
Wilson later measured both the cosmic background radiation
from Big
Bang (1965) and the predicted temperature. Its existence
convinced
virtually all skeptics that Big Bang was true.
EVIDENCE OF BIG BANG -NASA's Cosmic Background Explorer Satellite (COBE)
Since then we've had over 30 years of temperature measurements-
virtually all of which have confirmed the predictions.
For example,
NASA's Cosmic Background Explorer Satellite (COBE) itself
made tens of
millions of temperature measurements. Using a Far-infrared
Absolute
Spectrophotometer with unprecedented precision the Big
Bang background
temperature was shown to be 2.726 +/- .01 degrees Kelvin.
Moreover,
these thirty years of measurements embraced wavelengths
from 0.04 to
70 cm-- and virtually all were consistent with the COBE
measurements.
But all of the temperatures measured had almost the same
value. The
enigma was that Big Bang did not predict so smooth a cosmos.
The
temperatures varied by a mere 30 millionths of a degree
Kelvin.
Causal processes in Big Bang did not explain the millions
of minute
thermal fluctuations revealed by the COBE measurements.
Instead, and
as was later realized, the small ripples were the result
of density
perturbations that had attended the birth of our universe.
These in
turn were found to arise from "quantum fluctuations" that
are
described in a modified "inflationary" form of Big Bang
proposed by
Alan Guth in 1981.
Guth suggested that in the very early moments of Creation
(less than
a millionth of a billionth of a billionth of a billionth
of a second)
our universe underwent a rapid "inflation". Guth's "New
Inflationary
Theory of the Universe" explained the observed thermal
smoothness,
and it also predicted that quantum fluctuations (and therefore
density perturbations) would occur during this early inflation.
When COBE's Differential Microwave Radiometer confirmed
0.01%
smoothness and Cosmic Background Radiation fluctuations
of thirty
millionths of a degree Kelvin, Big Bang's acceptance was
virtually
unanimous. Moreover, the existence of the thermal inhomogeneities
that seeded primeval structure in the early universe was
established.
EVIDENCE OF BIG BANG - Additional Data
Big Bang also predicted the existence of a nucleon / photon
"Concordance Interval" that experimental data now shows
lies between
3 and 4 ten-billionths. Big Bang also predicted primordial
"nucleosynthesis" that is now confirmed by numerous measurements,
and
inferred the measured primordial abundances of Hydrogen,
Helium and
Lithium isotopes (D, 3He, 4He and 7Li). But before leaving
this, let
me share one other fact (among many) that give us assurance
that Big
Bang is on solid footing.
In April, 1994 Antoinette Songaila and Lennox Cowie of
the University
of Hawaii, and Craig Hogan and Martin Rogers of the Washington
University used the world's largest single mirror (ten
meter) Keck
telescope on Mauna Kea to measure the absorption of quasar
light
through a primordial gas cloud. Their measurements established
at
least three things:
1. Our universe is steadily expanding and cooling,
and has done so
continuously in the past;
2. Two atoms of Deuterium exists for every
ten thousand of hydrogen;
3. The gas cloud has a temperature of 7.58
degrees Kelvin and is
twenty-five percent the
present age of our cosmos.
All of these results are consistent with, and predicted
by Big Bang.
ATHEISM UNGLUED
As I mentioned earlier, many Christians regard Big Bang
with disdain.
Their belief that Big Bang is untrue is the same as that
of many
atheists who still reject Big Bang. In times past virtually
all
scientists also disbelieved Big Bang, and did so for hundreds
of
years, favoring instead the "Steady State" theory of the
universe.
Numerous atheists disbelieve Big Bang because it implies
God's
existence. Scientists once disbelieved it because it violates
the
"First Law of Science" (thermodynamics). The First Law
asserts
conservation of energy. Energy can take many forms. It
can even take
on the form of physical matter (Einstein's famous conclusion).
But
energy can neither be created or destroyed.
For example, consider water. It can take the form of a
liquid, solid,
gas or plasma, or be further decomposed into quarks, fermions
and
gluons. But it always exists as something. In the
same way, our
universe consists of many things, and these appear in
different
forms. But a natural process cannot bring into existence
something
out of nothing (the First Law). This would be creating
energy.
Since things exist, and since a natural process could not
have
brought them into existence out of nothing, scientists
concluded that
they must be eternally existing. This should not be confused
with
quantum fluctuations, where Heisenberg's principle permits
virtual
particles to be continuously created and returned to Dirac's
"vacuum".
These exist over time intervals much too small for energy
capture.
Stated differently, perpetual motion machines are still
forbidden.
The idea that everything in the universe has existed forever
led to
the Steady State theory of the universe-- a theory that
was globally
accepted and adhered to for hundreds of years. But Big
Bang changed
all of that. It asserted that not only was there a beginning,
but
that the (Guth) equations could be viewed as teaching
everything
originated from "nothing". Since the sum total of all
the positive
energy of our universe (mass, radiation and so forth)
is, to within
an order of magnitude, equal to the negative energy of
gravitation
throughout the universe, the idea is not as far fetched
as appears at
first glance.
BIG BANG'S MEANING
What is Big Bang? What does it say? First let me make clear
what it
does not say. It says nothing about the origin of the
earth or the
origin of man. In fact, it says nothing about the origin
of planets
(except in the Alice in Wonderland agenda of whimsical
reductionists).
It does provide a working hypothesis (not a theory) as
to how
galaxies may have formed, as well as a description of
the nature of
space-time.
Big Bang says that our universe exploded into existence
in the form a
curved four-dimensional "space-time" fabric. The curves
in the fabric
tell matter how to move, and the matter in turn tells
the fabric how
to bend. The amount of matter in a given space is called
"density",
and space that is dense contains a large amount of matter.
Since our universe is expanding i.e., enlarging, the amount
of matter
that it contains in relation to its space is diminishing.
This means
that its mass density continues to get smaller. An important
astrophysical question is whether our universe will continue
to
enlarge forever, or stop expanding and collapse.
The answer lies in the amount of matter that occupied its
space at
birth. If less than a critical amount, the universe is
said to be
"open" and calculations show that it will expand forever.
But if the
amount of matter now occupying space exceeds this critical
amount,
then space-time curvature is "closed" which means that
one day the
universe will stop expanding and collapse.
MIRACLE OF BIG BANG
What is astonishing is that one second after creation,
space-time
curvature was neither open nor closed, but flat to within
one part in
a trillion, trillion, trillion, trillion, trillion. This
means that:
(a) the spacial and
energy distribution of the mass;
(b) the total amount
of mass;
(c) all of the physical
properties of this mass;
(d) the way that mass
unfolded within space-time curvature--
All of this must have occurred with miraculous precision.
Stated
differently, it teaches that our universe was tuned at
inception to
better than one part in a trillion, trillion, trillion,
trillion,
trillion!
Let me summarize this in as simple a way that I can by
examining the
question: "What does the Big Bang theory imply?"
The answer has four parts:
(1) Our world had a beginning;
(2) Space-time's fabric arose from nothing;
(3) It was supernaturally tuned at inception to
better than 10 multiplied by itself sixty times;
(4) The Bible proved trustworthy.
The first point is agreed to by virtually all astrophysicists
and
cosmologists world-wide.
The second inference comes from the way that Guth's equations
can be
viewed, and also from Peeble's work at Princeton University
which
shows that the sum total of the positive energy of our
universe (mass,
radiation and so forth) is, to within an order of magnitude,
equal to
the negative energy of gravitation that permeates our
universe.
The third point arises from the fact that each of the models
of our
universe-- no matter how diverse, all agree on one point:
Space-time
should have gone out of existence in less than one ten
millionth of a
billionth of a billionth of a billionth of billionth of
a second (an
interval known as the "Planck" time).
Five independent time estimates ALL give an age for our
universe of
between 12 and 18 billion years. When combined, these
results lead
any rational observer to conclude that our world seems
to have been
supernaturally tuned at inception. I say "supernaturally"
because all
known natural processes yield precision (harmony among
and throughout
all system phase points) necessarily less than 5 or 6
decimal places.
How ironic that some Christians fight the very understandings
that
have disclosed the evidence for a Creator.
NEW WORLD VIEW
The fourth point comes from what the Bible teaches, and
our new world
view that is emerging from modern knowledge. Make no mistake
about
it. The quantum world view and the Bible agree. Of course
this does
not mean that one can "prove" the Bible true. Rather,
it is more
accurate to say that the Bible self-evinces its own authenticity,
and
that all objections against the Bible can be dislodged--
and arise
either by reason of hidden presuppositions, or from honest
confusion
over the subject matter.
There are of course, die-hard reductionists who will go
to their
graves insisting that all that exists is matter and its
motion.
However this intellectual relic has been trampled underfoot
by the
growing disclosures of Quantum Physics-- but that must
wait for
another day.
Likewise Big Bang implies that our universe is characterized
by
thermodynamic closure (not to be confused with cosmological
closure).
This means that the conclusions of modern Thermophysics
can be applied
to the question of life's origin. Here again, the Bible
shines across
the reductionist chaos.
COSMIC YOYO
Materialists tried to fight Big Bang by alleging the expansion
was
one of many, and that the universe grows and then shrinks
eternally.
Peeble's put that to rest by showing that it can't happen.
The reason
is that not all of the energy created by destroying mass
on the way
out (expansion) can return to mass on the way back (contraction).
This means that each explosion must go farther than the
one before.
But this requires each earlier explosion to be smaller
than the one
that later follows. Computer calculations show that as
one goes back
in time, the "explosions" converge to a singularity i.e.
a beginning.
Thus "In the beginning" (the first three words of every
Bible) prove
correct even for a cosmological yo-yo. Moreover, in light
of the
supernatural tuning at inception, the next two words:
"God created"
now also appear to be correct. Actually, this latter point
can be
established more forcefully from the information content
of DNA.
OCCAM'S RAZOR
Let me close with a principle that is widely used in science--
and
then a question. The principle is known as Occam's razor
viz., "the
simplest explanation will most likely prove to be the
true one."
Now here's the question: What is simpler (and more reasonable)?
1. That specs of space dust endowed themselves
with a living
awareness of their
own existence to create such things as art
museums, concert halls,
bowling alleys and pizza parlors?
Or:
2. That the six billion intelligences
that now populate earth
originated from an
Intelligence?
