Are radioactive dating methods really as accurate as they appear to be? I heard that to test this, lava rock sample from a volcanic eruption 200 years ago was sent to three separate laboratories... I cannot recall the exact figures but when potassium-argon dating was used the three participating laboratories each returned ages varying from a few million to several billion years! That is quite a large error margin... considering the rock sample was in fact only 200 years old.
