Relative dating verses absolute dating methods
These are often characterised as the norm, rather than the exception.I thought it would be useful to present an example where the geology is simple, and unsurprisingly, the method does work well, to show the quality of data that would have to be invalidated before a major revision of the geologic time scale could be accepted by conventional scientists.As an example of how they are used, radiometric dates from geologically simple, fossiliferous Cretaceous rocks in western North America are compared to the geological time scale.To get to that point, there is also a historical discussion and description of non-radiometric dating methods.What I want to do in this video is kind of introduce you to the idea of, one, how carbon-14 comes about, and how it gets into all living things. They can also be alpha particles, which is the same thing as a helium nucleus. And they're going to come in, and they're going to bump into things in our atmosphere, and they're actually going to form neutrons. And we'll show a neutron with a lowercase n, and a 1 for its mass number. And what's interesting about this is this is constantly being formed in our atmosphere, not in huge quantities, but in reasonable quantities. Because as soon as you die and you get buried under the ground, there's no way for the carbon-14 to become part of your tissue anymore because you're not eating anything with new carbon-14.And then either later in this video or in future videos we'll talk about how it's actually used to date things, how we use it actually figure out that that bone is 12,000 years old, or that person died 18,000 years ago, whatever it might be. So let me just draw the surface of the Earth like that. So then you have the Earth's atmosphere right over here. And 78%, the most abundant element in our atmosphere is nitrogen. And we don't write anything, because it has no protons down here. And what's interesting here is once you die, you're not going to get any new carbon-14. You can't just say all the carbon-14's on the left are going to decay and all the carbon-14's on the right aren't going to decay in that 5,730 years.There are two main categories of dating methods in archaeology: indirect or relative dating and absolute dating.
Relative dating includes different techniques, but the most commonly used are soil stratigraphy analysis and typology.
So the so-called absolute radiometric dating methods themselves are not absolute.
It is a misleading term which is much used by evolutionists in order to seemingly prove the unobservable old age of the earth.
Special emphasis is on demonstrating that discrepant results are not the exception, but the rule, and that arguments used to justify so-called good dates are, when closely examined, arbitrary and without foundation. But the reality of the day is that any method based on assumptions can never offer absolute results.
All radiometric dating methods rely upon important assumptions usually not mentioned by evolutionists... rely on these few basic assumptions: - Beginning Conditions Known - Beginning Ratio of Daughter to Parent Isotope Known (zero date problem) - Constant Decay Rate - No Leaching or Addition of Parent or Daughter Isotopes - All Assumptions Valid for Billions of Years - There is also a difficulty in measuring precisely very small amounts of the various isotopes Absolute dates do not necessarily tell us precisely when a particular cultural event happened, but when taken as part of the overall archaeological record they are invaluable in constructing a more specific sequence of events.
