Rubidium strontium dating half life

No matter how much you try, you won't make radiometric dating say that the world is 6000 years old. I have a question if the world is supposed to be 4.6 billion years old then why or how would Rubidium-strontium dating where rubidium-87 to strontium-87 has a half-life of 50 billion years.i think your question is incomplete, because it makes no sense logically or grammatically.In addition, Rb is a highly incompatible element that, during partial melting of the mantle, prefers to join the magmatic melt rather than remain in mantle minerals. The radiogenic daughter, Sr, is produced in this decay process and was produced in rounds of stellar nucleosynthesis predating the creation of the Solar System.Different minerals in a given geologic setting can acquire distinctly different ratios of radiogenic strontium-87 to naturally occurring strontium-86 (Sr as the parent melt.) Alchemists believed mercury was the most important of all substances because it encompassed solid and liquid, earth and heaven, and life and death.

And have we ever had one of these specimens reach a full half-life?

If you take the trouble to read the article ON THIS MATTER which YOU ASKED FOR in the religion/philosophy forum you will find the answer.

The article I referenced gives a complete explanation of isochronic radiodating techniques, including Rubidium-Strontium dating.

The basic theory of radiometric dating is briefly reviewed.

Since 1955 the estimate for the age of the Earth has been based on the assumption that certain meteorite lead isotope ratios are equivalent to the primordial lead isotope ratios on Earth.The geological time scale and an age for the Earth of 4.5 b.y.Geber, Jabir ibn Hayyan, born in Persia (Iran) in the 6th Century A. Geber systemized and brought experimental methods to alchemy.But if you are asking how we can determine the 4.6 Gya age of the Earth using the Rb-Sr radiometric dating when the half life of ⁸⁷Rb is 48.8 Gya, the answer is that you have to understand how radioactive decay and dating works. At its core, all that's going on in radiometric dating is counting particles, and of course the number of particles changes by virtue of radioactive decay.
