And you can make all of these assumptions without even having read their paper. What if their work rebuts what you just posted? You don't know that it doesn't and apparently your demolition of the argument has not stopped them from pursuing it (they may not have read your specific case, but I am sure that they have read their critics), putting it to the test of peer review, and achieving results. Again, another example of the fact that if it comes from the creationist side, it is IMMEDIATELY discounted.

I read the link AndrewC posted.They're claiming helium diffuses fast in zircons, and therefore the fact there's still helium in zircons means the earth is young. But the problem is that helium does not diffuse fast in zircons; according to the paper I cited, the activation energy for diffusion is 44 kcal/mol. On average, the thermal energy available to a helium atom at room temperature is 0.6 kcal/mol. Below 190C, helium does not diffuse significantly at all.
