Dr
John G. Hartnett received his Ph.D. in Physics, with distinction,
from the University of Western Australia, where he is currently
a Post-Doctoral Fellow.
His current research interests include ultra-low–noise radar;
ultra-high–stability microwave clocks based on pure sapphire
resonators; tests of fundamental theories of physics, such
as Special and General Relativity; and measurement of drift
in fundamental constants and their cosmological implications.
He has published more than 30 papers in refereed scientific
journals and holds two patents. |
How
did our universe come to be? This is one of the ‘big’ questions,
and scientists who study the origin and history of the universe
(cosmos) are called cosmologists. Nearly all modern cosmologists
believe that everything was ‘kickstarted’ by a ‘big bang’1 about
15 billion years ago, where the universe suddenly emerged from an
extremely hot and dense state.2 But one dissenter from this ideology
is Dr John Hartnett—this makes him a ‘rare breed’ of physicist.
He is one of a relatively small number of Bible-believing creationists
worldwide involved in cosmological research and thinking.
Facts
vs their interpretation
Dr John G. Hartnett When they view distant stars that are millions
of light-years away from the earth, many folk, including Christians,
have trouble accepting the biblical account that God created the
universe about 6,000 years ago. But believing the Bible right
from the start is not a problem for John, which puts him at odds
with his evolutionary counterparts.
Often they will accuse him of denying reality (‘look, we can see
it—it’s obvious’). But John explains that when looking at the
universe, it’s no different to looking at the fossil record. ‘It’s
the interpretation of the evidence’, he says. ‘Sure, distant stars
and galaxies might be millions of light-years away, but that doesn’t
mean that it took the light millions of years, by our standards,
to get here. A light-year is a measurement of distance, not time.
[It is the distance that light would travel in a year through
a vacuum at its current speed of 300,000 km/sec (186,000 miles
per second), i.e. 9,461,000,000,000 km (5,878,000,000,000 miles).]
In other words, it’s just an expression used to tell us how far
away something is—not how long it took the light to get here.’
John did not always believe in Genesis creation. He explains that
he was interested in cosmology from a very young age, and mixed
with those of similar interests. When John was 16, he and a friend
co-authored a cosmology book that won a local science contest.
Big bang founded on unprovable assumptions
He says, ‘At that time, I would have described myself as an atheist,
believing that the big bang had all the answers, although there
was actually very little in the way of specifics about this model.
It was this that drove me into further investigation. Interestingly,
most people think that the big bang has already been worked out,
but they don’t realize that there are differing versions of the
big bang model—and not everyone agrees. By inserting a few unprovable
assumptions at your starting point, you can end up with virtually
any model you like.
The
big bang assumes that the universe has no centre or edge. Not
only is this not proven, some recent research on redshift patterns
have badly damaged its credibility by indicating that our galaxy
is at, or near to, the centre of the universe.3
‘What I really find amusing’, he says, ‘is the way people from
various other fields of science often quote the big bang as if
it’s “set in stone”. I don’t wish to sound unkind, but because
they are not experts in this field, many of them have no idea
what the big bang is really all about and misunderstand it.’
At present, John is assisting another creation scientist, Alex
Williams, in compiling a book about the big bang from a creationist
viewpoint. ‘We really want to show the scientific weaknesses in
big bang thinking, and that you can’t fit it into the Bible’,
he says. Jokingly, he adds, ‘We actually want to create a big
bang of our own among the scientific establishment, and dispel
the myth of this cherished icon of evolution.’
Solving problems
John is not content simply to point out that a light-year is just
a measure of distance, but tries to explain distant starlight
from a biblical framework:
- The
way I see it, the Bible is true and the stars were created
on Day 4. Yes, the universe is very large but we also
have a very great God. My personal view is that the explanation
probably involves a certain amount of miraculous activity
during Creation Week.
- But
I don’t believe that we see any false information, like
“light created on its way.” This would mean that we would
be seeing light from heavenly bodies that don’t really
exist; and even light that seems to indicate precise sequences
of events predictable by the laws of physics, but which
never actually happened. This, in effect, portrays God
as a deceiver.
- This
is very different from creating Adam as fully grown, looking
like a 20-year-old, say, although he was really only a
few minutes old. Here there is no deception, because God
has told us that he created Adam from the dust, therefore
there cannot be any history of growing for 20 years from
an infant. But God has also told us that the stars are
real, and that they are signs, not just apparitions from
light waves.4
- There
is every reason to anticipate a logical scientific explanation
for all that we see. We don’t deny that some research
is still needed, as we don’t yet know all the details—just
as big bang theorists face various problems and challenges.’

In
fact, John thinks this is an exciting time to be a Christian,
particularly in the area of cosmology. He thinks that Dr Russell
Humphreys’ book Starlight and Time has broken new ground for creation
researchers in this area.
‘What Humphreys has done’, he says, ‘is show us another parameter
of something that most people view as a constant, and that is
time itself. Using Einstein’s Theory of General Relativity, he
has shown how time can vary depending on your position in space—it
affects your viewpoint. Time is slowed by gravitational forces.
A clock at sea level has been shown to run more slowly than one
on top of a mountain, because the one at sea level is affected
by more gravity. This is an effect known as time dilation, and
has been experimentally demonstrated.
‘Humphreys uses this to great effect in his model to deal with
the distant starlight issue. His cosmology starts with the earth
near the centre originally, then the universe rapidly expanding
in a “white hole” or black hole running in reverse. At the beginning,
gravity would slow earth “clocks” far more than clocks further
away, especially at the edge of the universe. Therefore, “billions
of years” would be available (measured by clocks in those distant
regions of space) for light to reach the earth, for stars to age,
etc.—while less than one ordinary day is passing on earth (measured
by earth clocks, on which biblical time is based).’ Cutting-edge
research John’s current work is directly related to this field.
As a research fellow with a prestigious secular university, he
is part of a team that develops technology for very precise atomic
clocks (see box, below). He explained that the clocks are so precise
that they might only gain or lose about one second of time every
400 million years. ‘They tick so fast—about 10 billion times a
second—that we can directly measure infinitesimal losses.’
Cosmology and Christianity
John adds that since he became a Christian, he regards it as his
‘calling’ to make cosmology more understandable for the average
layperson. He says, ‘Modern ideas about the origin of the universe
contain lots of complicated mathematical theories and formulas.
Many people are duped into thinking that because two plus two
equals four, the maths of the big bang must be right. But in most
cases, these formulas are not provable or testable—they remain
completely theoretical, and the models they support are based
on unprovable starting assumptions. Christians, in particular,
should not be worried about this.’
He is particularly critical of Dr Hugh Ross’s beliefs. That is,
Ross ‘reinterprets’ Scripture to claim the days of Genesis 1 were
long ages, and tries to use the big bang as a proof of Christianity.
He observes, ‘Hugh Ross is on very shaky ground—placing his faith
in this model, particularly when the real big bang leaders seem
not to agree that the theory implies a creator.’
When I asked him about his history as a Christian, he reminisced
about his young co-author friend. He recalls, ‘He got saved, and
I became quite bitter towards him and other Christians. I used
to go along to meetings and torment them. At one meeting I even
tipped over a table full of books and stuff. I challenged them
on evolution and origins, and they always avoided the subject.
Looking back, though, I can remember having some doubts—a sort
of belief in God, so if someone could have shown me some scientific
basis like creation—in the Bible—I think it would have had a big
impact on me.’ Sophisticated sapphires Dr John Hartnett showed
us these man-made sapphires. Very pure crystals of aluminium oxide,
they are used in the oscillator pumps his team develops for atomic
clocks. He said, ‘The ones we are using in our clocks right now
would cost around US$20,000 each. We’re currently working with
the European Space Agency in developing technology to test their
atomic clock that is going to be used on the International Space
Station. The precision of clocks like those can be used to measure
the effects that gravity has upon time, even on earth.’
Years went by, and John became a Christian during the third year
of his undergraduate degree in physics. Meeting other Christians
after that, one young man challenged him to read Genesis, saying,
‘Read the first part, and when you’re finished, I’ll come back
and talk to you.’ John says, ‘When I started reading it—it was
like—wow, unbelievably amazing. Straight away it struck me that
this could be completely consistent with the scientific evidence
and the knowledge I had at that time. I was being converted into
a creationist there and then.’
In their enthusiasm, John (by now married) and his wife strayed
for a while into a quasi-Christian cult. He remarks, ‘We thought
we were serving God—we were so keen. But looking back, I don’t
think we ever really fitted in, and we now realize our mistake.’
John
realizes that the distant starlight issue is a major stumbling
block to belief in the Bible; the controversy, he says, is aimed
squarely at the Genesis account of creation, which is foundational
to the gospel. He says, ‘I can understand it being an issue—it
was a problem for me, too. But now I know that God did create
it all, and when He says He did, I’m just eager to find out more
about how. And, in the process, to help Christians give increasingly
powerful answers to defend and share their faith.’
