Early in 1987, The Society for Creation Science, a student organization, invited me to speak at the University
of Tennessee in Knoxville. My presentation entitled "Should Creation Science Be Taught at UT?" was publicized
in the student and local newspapers, The Daily Beacon and the Knoxville News-Sentinel, and on
local radio and television networks. A few weeks before my program I wrote Dr. Press and other evolutionists,
challenging them to come and present any evidence which invalidated my results on creation. About 600 persons
representing a cross section of community, students, and faculty came to the Alumni Gym on the evening of April
13, 1987. Neither Dr. Press nor any of the other invited evolutionists came, but some did come from the UT
geology department. Their presence made that evening a memorable occasion.
In my talk I used a familiar example to illustrate why polonium halos in granites are unique evidence of
creation. A glass of water was placed on top of an overhead projector that was focused on a very large screen in the
front of the auditorium. Then I reminded the audience that according to evolutionary theory the granites had formed
as hot, molten rock slowly cooled over millions of years of geological time. To illustrate that polonium halos could
never form under these conditions, I compared the effect of a tiny speck of polonium in molten rock with an Alka-
Seltzer tablet which was then dropped into the glass of water. The beginning of effervescence was equated to the
instant that polonium atoms began to decay and emit radioactive particles. I explained that traces of those particles
would disappear as quickly in "liquid" rock as bubbles from the Alka-Seltzer disappear in water. But if the water
were instantly frozen, the bubbles would be preserved. These frozen bubbles would be analogous to the
exceedingly large number of polonium halos now encased in granites around the world. Just as frozen bubbles
would be clear evidence of an instantaneous freezing of water, in like manner polonium halos are undeniable
evidence that many rapidly "effervescing" specks of created polonium interacted with a sea of primordial matter
that was almost instantly "frozen" as solid granite.
Next I discussed the falsification test and was answering a question when someone spoke out from the
audience. I encouraged him to come down front to the microphone, for it was apparent he had strong feelings which
he wished to express. The following exchange of comments was taken from the videotape of the evening's
presentation:
[p. 198]
UT PROF: My name is _________, a professor of geology at UT. Who said you cannot form
a granite in the laboratory? It's been proven for 25 years, by hundreds of publications, and just because you are
ignorant of [those] publications, doesn't mean that it can't be done. I can do it in my laboratory. People all over the
world can.
GENTRY: You know, I am just so happy you came forward tonight. I am absolutely gratified, because
I will give you the piece of granite. How long is it going to take you to do it?
UT PROF: Under controlled cooling rates, you can form it in about a week.
GENTRY: Can we all come back in a week, and . . . see it? Just like this?
UT PROF: In that approximate grain size, not that size, obviously. It would have to be much
smaller.
GENTRY: Oh, wait a minute. What was this about the grain size now?
UT PROF: That approximate grain size is controlled, is a function of the cooling rate, the kinetics of
the situation, the crystallization and growth. And you can form that coarseness of granite minerals; you can form
those mineral compositions with a cooling rate of about ½ degree per hour crystallizing.
GENTRY: I want to show you a piece of biotite, a piece of granite, which contains the polonium
halos. Why don't you look at it? . . . How long do you think it would take you to do this? This one. [I
handed him the larger piece shown in Plate 11-b of the Radiohalos Catalogue.]
UT PROF: That? The grain size, and I don't know exactly [which] mineral compositions are there, but
I estimate the same approximate cooling rate. Anything slower than ½ a degree per hour over the crystallization
range of approximately 200 degrees over which these minerals crystallize will be sufficient to do this.
GENTRY: And will in a week . . . ?
UT PROF: And people at UCLA, at Cal Tech, at Chicago, at MIT, at Harvard, at . . .
wherever you want to go, can do this. So I don't see that it's a big problem. Frank Press is from MIT, and that's
where, I mean, he would be speaking to that. But I think more properly that the reason why you are not getting a
rebuttal to this is that people just don't want to rebuttal [sic] it. . . . It is so well established in the
literature.
GENTRY: Now, is this the first time that you have heard of this test?
UT PROF: Yes, it is.
GENTRY: I see. So you think that in one week you can get this piece of granite back in your
laboratory?
UT PROF: I can give you . . . many, many publications about . . .
[p. 199]
GENTRY: No, no. I am not talking about publications. I am saying, you have claimed tonight
that you can do it, is that true?
UT PROF: I don't have my laboratory set up right for doing that particular thing. I'm working on
basalts, but, yes, you can do that.
GENTRY: . . . I think that . . .
UT PROF: I will tell you the laboratory where I could go and do it, and that would be at Johnson
Space Center. They do that down there now.
GENTRY: Now you changed the topic just a little bit, and I think the audience needs to be aware that
you have gone from a granite to a basalt. And they need to understand the difference. . . . there is an
awful lot of difference between the grain size of the basalt you are talking about and the granite crystal which I
have right here. . . . [Same piece shown earlier.]
UT PROF: I beg to differ. I beg to differ tremendously, that there can be grain size within a basalt
flow, within the Hawaiian flows, that is of the same grain size as you have there . . . that can cool, that
can form rather rapidly. But regardless of . . . I am not talking about basalt . . . I don't
know what your . . .
GENTRY: You mentioned basalt.
UT PROF: I said, I'm—what I have been working on recently is basalts.
GENTRY: Well, I have to comment . . . further on what you've just said .
UT PROF: Well, okay, . . . what I am saying is that you can make the grain size of the minerals; you
can make the mineral compositions without any problem in the laboratory, . . . when you are geared
up to do this particular type of thing. It takes controlled cooling rates, in closed containers. You cannot
. . . you could make something grain-sized; hand-sized—but we don't make them that large; we
have problems with containers; we make them smaller. So we make them on the order of just a few, you know, five
millimeters, six millimeters across. We are not making a hand-sized . . . in fact, we can duplicate
everything, and it has been done for many, many years.
GENTRY: . . . Well, let me ask you this question. Following now on the comments you just made in
the . . .
UT PROF: . . . I'm sorry, . . . but I feel that I'll be willing to show you the literature. I'll be willing to
talk to you about demonstrations, whatever you want. But I am not about to come up and, and sit here and have you
change things around about basalts and granites. I mean it is well established in the literature. I . . .
can give you that. (Applause)

His bravado had an effect on the audience. Everyone present realized that the battle lines were very
clearly drawn, and the vigorous applause given after the geology professor's remarks showed he had supporters for
his position. Some of my friends later told me they were concerned my case was lost at this point. But they, along
with most everyone else present, were unaware of some extraordinary events that had transpired over the preceding
month. In the next several minutes they would hear me recount how those events had dovetailed to bring into focus
a largely overlooked prediction in my book concerning any attempts to synthesize granite.
