That the He diffusion rate is low is a different problem. The author makes a point about the diffusivity of rock being a very very sensitive function of its temperature, e.g. a factor of 2 in inverse temperarture makes a difference between a 100 year time scale and a billion year time scale for diffusion. But he explains it away as follows:
that although approximately 1.5 billion years of U/Th decay at today’s decay rates occurred within the GT-2 borehole rock [e.g. the rock is actually 1.5 billion year old], helium generated by that decay had only been escaping for about 5,700 years, which is why large amounts of helium were still present in the zircons. This discrepancy can be resolved if there was a time in the past in which nuclear decay rates were much higher. This is strong observational evidence that at some time in the past, accelerated nuclear decay did occur.
In other words, the world is only 5,700 years old, but the first few years of that the clok was running so slow that it is the same as if it were 4.5 Billion years old. We bring biblical and geological time into sync by assuming a time warp. [this is what is called a coordinate change, but it is a fundamental law of physics that the laws of physics are immune to coordinate changes - e.g. we don't transform lead into gold or BS into philosophy by switching from English to metric units].
Science will NEVER prove or disprove the existence of god. Any christian that attempts to “prove” the existence of god citing scientific study is FAITHLESS.
