Dendrochronology absolute dating method
Patterns of seasonal variation are mostly unique and recognisable, and can date wooden artefacts, furniture, structural timbers in historic buildings, bridges and ships, or finds of wood from excavations.
In well-preserved samples, the date of felling can be refined to within a season of a particular year.
Radiometric dating--the process of determining the age of rocks from the decay of their radioactive elements--has been in widespread use for over half a century.
There are over forty such techniques, each using a different radioactive element or a different way of measuring them.
Note however that the date of felling is not the same as the date that the timber was used.
It may have been stored for many years to 'season' before being used in buildings, etc and then reused a second time before it finally ended up in archaeological deposits.
By the end of this tutorial you should have a basic understanding of: The available astronomical data indicate that the universe is about 13.7 billion years old.
This estimate is based, in part, on the observation that the universe is constantly expanding.
It’s important to remember that we have limited data, and new discoveries have often overturned previous ‘hard facts’.
Many Christians have been led to distrust radiometric dating and are completely unaware of the great number of laboratory measurements that have shown these methods to be consistent.
Many are also unaware that Bible-believing Christians are among those actively involved in radiometric dating.
Astronomers have plotted the trajectories (directional movement) of various stars and galaxies and determined that all matter in the known universe arose from a common point.
In an event often referred to as the "Big Bang," the universe arose in a relatively brief moment in time and matter was flung outward from this central origin.
