The age of the earth

by Richard on July 12, 2010

I doubt I’ll be able to do any blogging today, but before I sign off, this headline on the BBC caught my eye: Earth younger than previously thought, say scientists. The article says

A new geological study has set a more accurate age for planet Earth, according to scientists.

Researchers say their investigation shows the Earth is 70 million years younger than the 4.537 billion-year-old planet “we had previously imagined”.

Here’s my question. How does a revision of 1.5% on a geological age make a headline?

It’s still an old fart as far as I’m concerned - but it’s the thin end of the wedge for creationists!

It will be when it is cited by some statistically illiterate young earther to prove the inaccuracy of geological dating methods…

Still older than Kim - just!

I wonder what the margin of error is for the data? Probably around 1 or 2% anwyays… so I also don’t see how this is newsworthy… 4.5 v 4.6 billion years doesn’t really change much for most of us. Maybe if they had to revise the date by 10-20% that would be astonishing… but 1 or 2% reflects increasing accuracy, or just play within the margins.

Phil, increasing accuracy? Not if there is a predisposition toward an old earth by the researchers themselves. Kind of a “self-fullfilled prophesy” when it comes to these issues. Even under peer-review the peer-review can have predispositions going into the review which support the self-fullfilled prophetic results as well.

Hey Paul, as Satchel Paige observed, the key question is “How old would you be if you didn’t know how old you were?” In any case, in dog years - not to mention baptism - I’m already dead.

A thought: to make the earth at least look younger, how about a global Botox and some implants in the Alps and Himalayas?
