Radiometric Dating - American Scientific The only dating methods discussed (over and over) by evolution-believing scientists and the mass media are those that supposedly "prove" that the earth is billions of years old. Radiometric dating ques indicate that the Earth is thousands of times older than that--approximately four and a half billion years old. Many Christians.

Absolute dating involves determining a rock's actual age as a number of years. Radioactive or radiometric dating is a very important method of determining an.
Chapter 4 When? Dating Methods and Chronology Another pertinent thing that's also nored, minimized, or scoffed at are the numerous other scientific methods of dating the earth, solar system, and or universe that yield much younger ages than 500 million years (max). When a rock crystallises, the crystals of the minerals in the rock often enclose minute grains of other minerals which contain uranium and thorium. To know how old sequences, sites, and artifacts are in calendar years, absolute dating methods must be used. Absolute dating relies on regular, time-dependent.
