Young Earthers point to an infamous dating error as evidence that the Earth is only as old as the Bible says.by Brian Dunning Filed under General Science, Natural History, Religion Skeptoid Podcast #146 March 24, 2009 Podcast transcript Today we're going to point our skeptical eye at one of the key players in the debate between geologists and Young Earthers over the age of the Earth. Steven Austin took a sample of dacite from the new lava dome inside Mount St. The dacite sample was known to have been formed from a 1986 magma flow, and so its actual age was an established fact. Austin submitted the sample for radiometric dating to an independent laboratory in Cambridge, Massachusetts.The results of this research were published in the journal , and Professor Tatsumi is planning a voyage to the site in March to confirm the findings.They will use underwater robots to unravel the processes that resulted in the volcano’s formation, and use seismic and electromagnetic methods to determine the existence of a sizeable accumulation of magma.



Members are from all walks of life, and their profiles are unlikely to offend even in the Not an easy site to get around; search options are very limited when compared to others.If I take a sample and measure an argon to potassium ratio of 0, I know that this sample is 2.4 billion years old.However, all of these numbers are probabilities, not absolutes.Upon further inspection, a distortion in the dome’s surface suggested a growing chamber of magma inside it.

The discovery of the lava dome does not necessarily mean the next supereruption is right around the corner, but a developing magma chamber could be capable of triggering just such an eruption, according to the scientists.

Obviously both sides of this debate have agendas to promote, and that means that any summary you're likely to read was probably motivated by one agenda or the other.
