Helium Diffusion in Zircons
The authors argue that by extrapolating data on the rate of helium diffusion in minerals, the high concentration of helium in zircons can only be explained by a young earth. However, the data presented were taken in conditions of laboratory vacuum and actual diffusion rates in field conditions are known to be considerably lower, by as much as a factor of one thousand or more. The RATE researchers claim to have meticulously accounted for all crystallographic features. However, the diffusion rate of noble gases in minerals is so complex both theoretically and experimentally that helium concentrations are not considered by geochronologists to be reliable for any dating implications.

Ok, we had a time warp. For the first 4.5 years of the earths life, we slowed down our clocks to 1 billion years per year, so the half-life of various uranium isotopes went from a billion year time scale to a one year time scale. Then 5,700-4.5 years ago we switched our clocks to run at 1 year per year. You can play silly games like that, but it changes nothing. It's like announcing the first 8 innings of a baseball game standing on your head and then standing upright for the last inning. The world order wasn't reversed by this parlor trick.
