Professor Hartnett, now retired, is an adjunct
associate professor in the Institute for Photonics
& Advanced Sensing, and the School of Physical
Sciences, at the University of Adelaide, developing
ultra-stable clocks. He has published more than
100 papers in peer-reviewed scientific journals.

embryos’ orbits, which begin to
cross. A cascade of collisions
follows, forming planets as the
embryos merge and collect planetesimals. Leftover planetesimals become asteroids.1
In the actual observed solar system, the
planets Venus and Earth are comparable
in mass, and orbit between the smaller
planets Mercury and Mars (see Fig. 1a).
But standard computer models have
what is known as the ‘Mars problem’.
That is, in place of Mars, another planet
forms, which is comparable in size
to Earth, and additional Mars-sized
embryos can readily get stuck in the
asteroid belt. Another way of putting it is
that, according to the best models, Mars
is supposed to be at least as massive as
Earth, when in fact it is a bit more than a
tenth of its mass—and the main asteroid
belt should most likely include several
objects the size of Mars, when in fact
there are none.
[The] main result is that, no
matter what the density profile,
it is impossible both to solve
the Mars problem and to build a
correctly structured asteroid belt
(fig. 1b, c).1
I have previously discussed the problems of star formation via the solar
nebular theory. 2 Creationists have also
frequently written about the difficulties of solar system formation from
that alleged nebular cloud without
a Creator. 3 This new research highlights another intractable problem for
Why not admit that man is deficient
in his knowledge? Our all-knowing God
has told us that He created the planets of
the solar system, and that this was about
6,000 years ago. God said He created
the ‘stars also’ (Genesis 1: 16). 4 He said:
“… my right hand has spread out the
heavens; when I call them, they stand
forth together [meaning He created them
at once]” (Isaiah 48: 13).
