So we have to rely on something called radiometric dating to figure out the age of rock.Because these rates do not change and because the radiation that rocks give off can be measured, it became possible to calculate the time the rock was formed or, in other words, the rock's birth date - give or take a few thousand years or so.They were missing something absolutely fundamental. We are missing perhaps something as profound as they were back then.— David Gross at 23rd Solvay Conference in December 2005 Radioactive dating is a key concept in determining the age of the earth.Many secular scientists use it to dismantle the faith of Christians and cause them to accept uniformitarian assumptions that, in addition to being scientifically erroneous, demand a figurative and distorted interpretation of Genesis.Being knowledgeable about such a widespread dating method is essential for Christians to address opposing arguments and critics. Natural radioactivity was discovered in 1896 by the French physicist Henri Becquerel.

Many of us believed that string theory was a very dramatic break with our previous notions of quantum theory.

Regardless of which name you prefer, the discovery was a true breakthrough that provided a tool to predict the geological history of the Earth and even the age of the Earth itself.

To better understand how radiometric dating helps us determine the age of rocks, it will help us to gain a better understanding of how elements decay.

Measuring the uranium-to-lead ratios in the oldest rocks on Earth gave scientists an estimated age of the planet of 4.6 billion years.

Segment from A Science Odyssey: "Origins."Geologists have calculated the age of Earth at 4.6 billion years.
