Age dating old

New research shows that, at least for the Sami people of preindustrial Finland, men should marry a woman almost 15 years their junior to maximize their chances of having the most offspring that survive."We studied how parental age difference at marriage affected [families'] reproductive success among Sami people who married only once in their lifetime[s]," says ecologist Samuli Helle of the University of Turku in Finland.From Wikipedia, radioactive decay is the process in which an unstable atomic nucleus spontaneously loses energy by emitting ionizing particles and radiation.This decay, or loss of energy, results in an atom (element) of one type, called the parent nuclide transforming to an atom of a different type (another element or another isotope of the same element), named the daughter nuclide.Other research in modern day Sweden has shown that the ideal reproductive match is for a man to marry a woman six years his junior.But the cultural constraints on marriage may have changed.

We have rocks from the Moon (brought back), meteorites, and rocks that we know came from Mars.When there is a scientific discussion about the age of, say a meteorite or the Earth, the media just talks about the large numbers and not about the dating technique (e.g. On the other hand, when the media talk about "more recent events," ages that are more comprehendible, such as when early Man built a fire or even how old a painting is (or some ancient parchment), then we bring up the dating technique in order to better validate the findings.Carbon is unreactive with a number of common lab substances: sulfuric acid, hydrochloric acid, chlorine, or any of the alkalis.This predictable decay is called the half-life of the parent atom, the time it takes for one half of all of the parent atoms to transform into the daughter.This may simply have to do with what the media is talking about.

When we age date a planet, we are actually just dating the age of the surface, not the whole planet.
