Yes, I know that polonium halos are put forward by an actual scientist and have some logic behind them, thats why I called them questionable (which
they are) and not false.
But there are even more experts who disagree with Gentry.
en.wikipedia.org... - references
Of course, you must have read what these scientists reported in their scientific criticism of Gentry:
"Numerous attempts have been made to counteract Gentry's claim and to show that Po halos are formed by less dramatic processes. None of these has
been fully satisfactory."http://www.csun.edu/~vcgeo005/revised8.htm
and the other, Brawley, is a self-proclaimed amateur scientist. However, he states: "Upon obtaining Dr. Gentry's book, "Creation's Tiny
Mystery," I found that there indeed seemed to be a legitimate claim being made: the requirement for long cooling periods (many, many years) in
granites, combined with an extremely short half-life for Polonium, made it seem quite impossible for particles of Polonium-218 (half-life around three
minutes) to have become entrapped in crystals of biotite which grew slowly to include them."
then he grips one single aspect to try to rule out all other possibilities:
"Hence, depending on multiple factors such as the configuration of cracks, buildup of Lead particles in them, new cracks or distortions formed under
geologic shifting, and other changing conditions, Radon-222 halos might be seen in all conceivable stages of development. Radon halos would be the
only types capable of continuing 'migratory' formation, since "Polonium," Uranium, and Thorium halos can only form around particles locked into
places in the biotite crystal lattice or transported by subsequent hydrothermal activity."
Simply faulty reasoning. Basically, he is saying that if a flag flies south in a north wind, another flag cannot fly east in a west wind.
They took on the world expert, made flawed and baseless arguments, and their cause celebre was adopted by anti-creationists without examination of
their texts and facts. That's called bias. Sorry....not buying it.
