Creation Ex Nihilo Technical Journal, 12, 287.
I welcome the opportunity to clarify some important issues concerning my
polonium halo research. Because of space limitations, I respond only to
Wise's most serious omissions and errors of fact.
For over thirty
years I have been publishing experimental results verifying that Po
halos in granites and other crystalline rocks did not originate with
secondary Po from U decay, but instead with primordial Po, and hence
constitute prima facie evidence of almost instant creation of those
rocks.1-8 What is most revealing about Wise's attempts to cast doubt
on the primordial nature of these halos is that he repeatedly ignores
the published scientific evidence which contradicts what he is attempting
to establish. As I will now show, what all this means is that the creation
implications of Po halos in granites now shines brighter than ever.
Consider first,
for example, that in my 1967 Nature report,1 I published that fossil
and neutron-induced fission tracks appear in U-halo centers in biotite,
but are absent from Po-halo centers, thus excluding U-bearing solutions
as the source of Po for those halos, irrespective of whether they occur
along tiny conduits--i. e., microscopic-sized microchannels--or whether
they occur in defect-free areas of the biotite where there are no cracks
nearby.
In sections 4d,e
Wise essentially ignores these results and attempts to link Po halos
in granites with secondary Po by assuming, as fact, the whimsical claim
he made in section 2c -- namely that it is impossible to avoid cracks
in biotite. The reason Wise is so dogmatic about the existence of cracks
is that he absolutely must have them to have any hope of justifying
the passage of the hypothesized secondary Po atoms from some distant
U source to the Po halo centers. In one instance he uses 'cracks' to
mean conduits along a basal cleavage plane, and in another instance
to mean visible erratic features associated with separations between
the cleavage planes. I now cite evidence showing that in both cases
Wise seriously errs in claiming it is impossible to avoid cracks in
biotite.
First of all,
anyone who wishes to do so may easily view spectacularly beautiful Po halos
in clear, conduit-free or crack-free areas in micas in the color-photo
catalog in my book. There, contrary to Wise's other claim, they can
also find Po halos in fluorite separate from conduits. Secondly, the
vast majority of perfect crystals of biotite - and I have worked with
a very large number of them - do not exhibit basal cleavage separations
unless something is done in splitting the mica in specimen preparation.
This I have demonstrated both by visual inspection before and after
prolonged immersion of the crystals into an aqueous dye solution before
proceeding with either peeling the biotite with scotch tape, or mechanically
with a sharp blade. Either of these procedures can induce cleavage separations,
but it is a non sequitur to imply - as Wise implicitly does - that these
experimentally-induced separations are the norm for the original unstressed
crystals. Clearly, an investigator can always choose perfect, defect-free
crystals to search for halos if he takes care to do so. But Po halos
in defect-free areas disprove Wise's claim that it is impossible to
get away from cracks in the biotite; this result in itself shows that
his speculations about the secondary origin of Po halos in biotite,
as described in his section 4, are without any scientific foundation.
And there is more.
In a 1968 Science
report2 I published a definitive study showing that fossil alpha-recoil
(α-recoil) analysis of many Po-containing mica specimens revealed no
excess of α radioactivity near Po-halo centers. The purpose of the study
was to test whether there was any evidence for any migration/movement/diffusion
of any hypothetical α-emitting precursors toward the Po centers. Such
movement would necessarily have been accompanied by the α decay of such
emitters as they moved toward the Po-halo centers along the same cleavage
plane containing the centers. The recoil nucleus from any α decay produces
a tiny recoil pit, or track, which is rendered visible by an HF acid
etch of the basal cleavage plane. In my study I measured the fossil
alpha recoil density in the basal cleavage planes above, below, and
through the Po halo centers. What one observes in these three areas
near the Po halo centers is the same α-recoil track density that is
common throughout the mica; the background density is due to the α recoils
from the parts-per-million (ppm) concentrations of U and Th.
I performed
about a hundred experiments, which showed that 'excess' α-recoil tracks
do not exist near Po-halo centers. In his section 4e, Wise attempts
to cast this result in doubt by claiming the absence of excess track
density is only apparent. Experiments show this is false. The excess
is truly absent. It is wrong to say the excess is only apparently absent.
Movement of any hypothetical α-emitting precursors toward the Po halo
centers would have left an excess of fossil α tracks in their wake.
And the excess would have been huge, for well-developed Po halos show
coloration corresponding to the decay of five billion Po atoms. These
results unequivocally disprove the hypothesis that Po halos in granites
originated from secondary radioactivity, showing instead that they originated
with primordial Po.
Neither Wise
nor anyone else has ever ventured to challenge these results in the
established scientific literature. Evolutionists would gladly have done
this if possible to do so, for the absence of excess α-recoil tracks
unambiguously shows there was no migration/diffusion of radioactivity
feeding the halo centers, thus powerfully disproving the secondary hypothesis
for the origin of Po halos in granites. And there is still more.
In the early
seventies, I published results on the ion microprobe analyses of Po-halo
centers in granitic micas.3-5 My book6 discusses why the
206Pb:207Pb
ratios reported therein are uniquely traceable to the radiogenic decay
of primordial Po. Wise mentions neither these reports nor my book.6
Nor does he mention my 1974 Science report,7 which showed quite definitively
that 218Po halos do not have a halo ring from 222Rn. This observation
rules out a secondary origin of Po halos, thus proving from a completely
different perspective that such halos could not have formed from secondary
radioactivity derived from U decay, but instead originated with primordial
218Po. Wise's failure to mention any of this raises serious questions
about his methodology in evaluating the implications of Po halos in
granites as they relate to Earth's instant creation.
Similar but
far more serious methodological questions arise because of his failure
to reference the discoveries in my 1976 Science report.8 That is, since
Wise contends (section 1) that Po halos in granite-type crystalline
rocks must somehow be halos that formed from secondary Po activity derived
from U decay, and hence would supposedly - in his way of thinking -
have their origin in a Flood-related event, one would have surely thought
Wise would have discussed my discovery of secondary 210Po halos in coalified
wood from the Colorado Plateau,8 which are very clearly Flood-related
specimens.
As I note in
my book,6 there are enormous differences between the primordial Po halos
in granite-type crystalline rocks, and the secondary Po halos in coalified
wood. In granite, the typical U concentration is in the ppm range. In
coalified wood it can amount to several percent, more than a thousand
times that in granite. In granite, except in unusual circumstances,
U-daughter migration is restricted to solid state diffusion, an extremely
slow process. In contrast, my 1976 Science report8 presented evidence
showing that U daughters in solution were quickly transported through
a gel-like wood matrix, thus providing opportunity for rapid collection
of secondary 210Po in lead selenide sites. This is how secondary 210Po
halos formed. Later this gel-like wood turned to coal with the halos
still intact.
Now in granite
there are four different types of Po halos; on occasion two or three
types can be seen microscopically in the same specimen of mica. This
situation is virtually impossible to reconcile with the hypothesis that
such halos formed from U-decay products because the different Po-isotope
half-lives mean that greatly different quantities of each isotope will
coexist. In particular, since the expected amounts are directly proportional
to the different half-lives, this means that at any given time the atomic
ratio 210Po:218Po should be about 67,000:1. Thus, if Po halos in biotites
were from secondarily-derived Po from U decay, there should exist about
67,000 210Po halos for each 218Po halo. This is definitely not the case.
In some mica specimens the number of 218Po or 214Po halos far outnumbers
the 210Po halos.
On the other
hand, this extraordinary large abundance of 210Po halos agrees with
what I discovered in the coalified wood specimens.8 Moreover, in examining
thousands of secondary Po halos in coalified wood, I have yet to find
a clear example of either a 214Po or 218Po halo. To summarize, the reason
for this disparity is that the 139-day half life of 210Po enabled a
sufficient number of these atoms to survive long enough in the gel-like
wood to be collected at the PbSe sites, where they decayed and formed
210Po halos. In contrast, the far more rapidly decaying atoms of 214Po
and 218Po - with respective half-lives of 164 microseconds and 3 minutes
- largely decayed away before they were collected at these same sites.
This is the reason for the absence of 214Po and 218Po halos in coalified
wood. That these latter two halo types failed to form naturally under
the very best conditions of high U-daughter concentrations - coupled
with rapid transport and ideal collecting sites - effectively removes
any scientific basis for believing they could have formed by some natural
process in U-poor granite.
This conclusion
is addtionally confirmed by the fact that primordial Po halos in granites
are uniquely distinguished from secondary 210Po halos in coalified wood
by the distinctly different 206Pb:207Pb ratios. The latter unambiguously
reflects an origin from U-decay products whereas the former can be traced
to the decay of primordial polonium. The scientific laboratory evidence
is clear and unequivocal: primordial polonium halos do exist in Earth's
foundation rocks, the granites. Biblically this is exactly what we expect
because their discovery in these rocks fits with the precise description
of the rocks God created in the beginning. 'In the beginning, LORD,
you laid the foundations of the earth, and the heavens are the work
of your hands' (Heb. 1:10).
Possibly Wise's
difficulty in accepting the Po-halo evidence for creation can be traced
to how he interprets earth history.9 The abstract of his talk at the
First International Conference on Creationism (1986) contains the following
statement: 'Geologists commonly use only three dating methods. Creationists
commonly claim each of these techniques is invalid. Carefully considered,
each technique has difficulties, but none of them can be considered
faulty enough to be invalid.'9 This position has enormous hidden implications
that need to be exposed. To say that creationists must show why dating
techniques are invalid actually presupposes their validity; this in
turn presupposes the validity of the evolutionary time scale. All this
is fallacious reasoning. In fact dating techniques don't date anything.
A 'radioactive date' is in reality only an inference obtained by interpreting
the ratio of the parent and daughter isotopes using the assumption of
uniform radioactive decay. It is indeed unfortunate that some creationists
have accepted this critical assumption when in fact the proven existence
of primordial Po halos in Earth's foundation rocks effectively disproves
the entire uniformitarian principle upon which all those dating techniques
are based.6,10-12
Despite this
overwhelming evidence of fiat creation, in his section 4 Wise ventures
from the scientific realm and joins others in wondering why, if God
chose to leave His fingerprints, He didn't leave other Po halo types
to prove instant creation. Wise says this absence seems strange to him.
There are many mysteries in the natural world, but I suggest this is
not one of them. Consider the following. Evolutionary geology holds
that granites with Po halos formed naturally. But in 1979, I claimed
this granite-Po-halo combination was a miracle of God's creation, impossible
to reproduce by any natural methods, and challenged the scientific community
to disprove it by first synthesizing a hand-size piece of granite and
then producing a 218Po in it.10 I repeated this challenge at the 1981
Arkansas creation trial,6 again at the widely-attended 1982 AAAS symposium,
`Evolutionists Confront Creationists,11 and since then at a number of
university-wide presentations, first at the University of Tennessee
in 1987, followed by Stetson University in 1989, Clemson University
in 1991, East Carolina University in 1993, Cornell University in 1996,
and North Carolina State University in 1997. There has been a deafening
silence to all these challenges.6
I believe this
proves conclusively that God did far more than needed to scientifically
validate His creatorship. So, what is truly strange to me is why some
evolutionists and others who question the granite-Po-halo evidence of
instant creation keep wondering why God didn't provide more evidence
for creation when, for over three decades, they continue to be baffled
by the Po halos which do exist in these rocks.
On the other
hand, I have proof that some evolutionists realize they already face
far more than they can handle. In November 1992 and November 1995 Dr.
G. Brent Dalrymple, the world-renowned evolutionary geologist who testified
at the 1981 Arkansas creation trial that Po halos in granites were a
tiny mystery that he would like to know the answer for,6 sent a pro-evolution
fund-raising letter to the multi-thousand members of the prestigious
American Geophysical Union. In both letters13 he stated something needed
to be done to counter the creation science movement, specifically mentioning
the problem that Po halos in granite was continuing to cause. In the
1995 letter he states the following:
'The [creation
science] movement is beginning to affect some college classes, too,
as members of "Genesis clubs" enter classrooms with disruptive (and
difficult to answer) questions. How would you answer a student who claims
that the presence of Polonium halos in granite demonstrates that granite
had to have formed suddenly (i.e., was specially created)?'13
Despite this
twice widely-publicized SOS to find a conventional answer for Po halos
in granites, we still hear nothing but deafening silence from evolutionists
on this topic. I therefore suggest that evolutionists - and all who
hold to a belief in an ancient, slowly-evolving earth - should not be
surprised when the scientific truth about God leaving His fingerprints
in Earth's primordial rocks begins to attract world attention. Indeed,
I believe God's special stones - the granites, Earth's foundation rocks
- will soon fulfill their special appointment with destiny as they cry
out (Luke 19:40) in calling men everywhere back to the worship of our
magnificent Creator God (Rev. 14:6-7).
