Some isotopes have half lives longer than the present age of the universe, but they are still subject to the same laws of quantum physics and will eventually decay, even if doing so at a time when all remaining atoms in the universe are separated by astronomical distances.Various elements are used for dating different time periods; ones with relatively short half-lives like carbon-14 (or C) are useful for dating once-living objects (since they include atmospheric carbon from when they were alive) from about ten to fifty thousand years old. Longer-lived isotopes provide dating information for much older times. What do you think about the knife that was found recently and dated to be millions of years old?Doesn’t that make you question the bible’s creation story?
The time that it takes for half of a sample to decay is known as the half life of the isotope.
These assumptions are not demonstrated, only supposed to be true.
To give an example of the complexity of this problem, this paper presents a study of the most popular dating method, potassium/argon.
In fact I knew nothing about radiometric dating and I must admit that learning about it seemed a bit intimidating.
I am also sure that this intimidation is what leads most people to just accept this type scientific statements as fact instead of taking a critical look at the process.
