How old is the earth?

I'm aware of the current take on temperature and pressure on decay rates. However, it's been shown that this is not always the case by experimental observation in physics labs where they do ab-initio computations. The work is in trying to figure out what is happening in the core of the earth.

I'll be more enthusiastic about encouraging thinking outside the box when there's evidence of any thinking going on inside it.

Aww, come on. Let's forego the generalities and get specific.

Which laws of physics? Are we talking about interactions under the strong nuclear force, weak nuclear force, or electromagnetism?

What kind of high energy bombardment? Electromagnetic, or with subatomic particles? And what energy spectrum - keV? MeV? GeV?

What kind of emission characteristics are changed? Does the high energy bombardment change the height of the nuclear potential well? Or its width? Or the thickness of the potential barrier?

And crucially, how much does the rate change? Does it change by enough to compress 4.5 billion years' worth of decay into 6,000 years'?

Because I know a bit about changing decay rates. One of my friends here did an experiment last year in which the group made beryllium-7 nuclei decay slower by cooling to under 10K.

The next time someone tries to tell me that the Earth is 4.5 billion years old based on radiometric dating of a chunk of beryllium-7 which has happened to stay under 10K somewhere in the Earth for a few billion years, I'll know enough to tell them: "That's a ridiculous date! The earth's actually older than that."

Until then ...

Which has got absolutely nothing to do with radioactive dating in igneous rocks.

This is simple geology - I learnt this in middle school. It wouldn't matter if radiioactive decay was effected by extreme pressure because the environment that minerals form are not in that system.

This is not high level science....

My geologist friend would disagree with you.

They are geology 101 texts that show you why the high pressure arguement is a red herring. Even you know that the high pressure arguement is misleading.......

I am saddened at your lack of understanding and knowledge.

And not citing anything is your MO.

How does your ideas on varves being a result of cyclic liquefaction account for the fact that there are two other bimodal events documented in varve layers; El Nino, and the 11 year sunspot cycle? Its not just that they are comprised of annual layers, you know. Its that the layers themselves can be cross-correlated to phenomenona and events observed by other, independent investigations...

Interestingly, the 11 year sunspot cycle also has a visible impact on tree ring growth, which provides scientists with an in-sample secondary check, in the event that an unsually high number off additional growth rings present an issue with the accuracy of ring growth dating...

My geologist friend would disagree with you. Igneous rocks can originate as partial melt directly from the core of the earth. Without knowing for sure the history of some of these minerals whose to say what kind of enviroments they came from.

Faure's textbook is certainly NOT geology 101 stuff. But high pressure condition (and problem) is NOT addressed in the book.

May be you regretted to cite this one. It is a popular geochron textbook in 80's (may be still is now). Many people read that book from cover to cover in geochron course.
