Alternatives to radiocarbon dating

As someone who has studied radioactivity in detail, I have always been a bit amused by the assertion that radioactive dating is a precise way to determine the age of an object.

This false notion is often promoted when radioactive dates are listed with utterly unrealistic error bars.

That’s just over half a percent error in something that is supposedly multiple billions of years old.

Of course, that error estimate is complete nonsense.

One theory proposed by Walt Brown suggests rapid production of radioactive elements through a known nuclear process called the Z-pinch (layman explanation at Real Science Radio).

Our purpose here is not to choose between alternative models, but to show that alternatives exist, and are even mandated by anomalies in the observed data compared to evolutionary theories.

A cartoony video from the American Chemical Society and PBS Digital Studios oversimplifies the matter of dating rocks. ”, written and delivered apparently by a homosexual who calls a boxer named Rock “dreamy” as if he wishes to “date” him, the video begins with an assertion: “The Earth is 4.565 billion years old, give or take a couple million years or so. ” The video proceeds to explain radiometric dating in simple terms, leaving only tiny bits of doubt at the end: “Not that they are satisfied, of course; geochemists are still fine-tuning their estimates of the age of the earth and looking for more evidence to support or diminish their theories.” The overall impression, though, is that dates of rocks and meteorites are well established down to four significant figures.

“But some zircon crystals may not be related to their host rocks at all.

They may have come from the source of the magma deep in the Earth’s crust or they may have been picked up by the magma on its way to the surface.

Unfortunately for the overconfident, those theories are plagued with anomalies. These hard minerals, often containing uranium, are presumed to lock in the parent and daughter elements.

But take a look at a picture in Phys.org’s article, “Zircon as Earth’s timekeeper: Are we reading the clock right?
