Mr Williams is a biologist, an honorary botanist at the Western Australian Herbarium, a former missionary, consultant to the U. His credentials are impressive and his interests appear to be in science, statistics and creation issues.
A serious problem here is that all 140 crystals from the same rock unit gave statistically valid information about that rock unit.
Indeed, using the measured rate of helium diffusion, these pre-Flood rocks have an average “diffusion age” of only 6,000 (± 2,000) years.3 These experimentally determined and repeatable results, based on the well-understood physical process of diffusion, thus emphatically demonstrate that these zircons are only a few thousand years old.
The supposed 1.5-billion-year age is based on the unverifiable assumptions of radioisotope dating that are radically wrong.4 Another evidence of a young earth is the low amount of helium in the atmosphere.
Helium diffuses so rapidly that all the helium should have leaked out in less than 100,000 years. While drilling deep Precambrian (pre-Flood) granitic rocks in New Mexico, geologists extracted samples of zircon (zirconium silicate) crystals from different depths.
The measured rates resoundingly confirm a numerical prediction we made based on the reported retentions and a young age.
Mainstream scientists make claims about the age of a certain rock unit.
The specific article written by Mr Williams was brief, a web version of an article he posted in The thesis of the article follows the usual YEC complaints of conventional absolute dating systems.
Even before I finished the project, critics began sniping at it.
The critics are usually atheists or professing Christians with various old-earth views.
During the radioactive decay of uranium and thorium contained in rocks, lots of helium is produced.
