The Grand Canyon: The age of the earth is not a purely academic matter.The deepest held values and beliefs of many people are tied into whether the earth has been around billions - or only thousands - of years.Consider, mud flows after the eruption of Mount St.Helens gouged sizeable canyons through solid rock in just a few days…Dividing the isotope concentrations of all the forms of strontium and rubidium by the isotope concentration of strontium-86 generates something called the "isochron." The isochron is then plugged into a model, which uses it to turn the overall radioisotope data into a clear, linear function.This function is able to tell researchers how old a sample is. But there's a wrinkle in the process that has been overlooked.The Bible says God created the physical universe in seven days.That doesn't leave a lot of time for life to evolve from primordial amino acids. On one hand, Hadrian's Wall has survived the erosional forces of wind and rain and ice for nearly 1900 years.

Researchers will need to evaluate samples individually, then apply the relevant physics accordingly.

The three isotopes mentioned can be used for dating rock formations and meteorites; the method typically works best on igneous rocks. The data from radioisotope analysis tends to be somewhat scattered.

So, researchers "normalize" the data by making a ratio with strontium-86, which is stable - meaning it doesn't decay over time.

The large difference in temperature between this hot fuel and the cold environment of space is applied across special solid-state metallic junctions called thermocouples, which generates an electrical current using no moving parts.

An oversight in a radioisotope dating technique used to date everything from meteorites to geologic samples means that scientists have likely overestimated the age of many samples, according to new research from North Carolina State University.
