The world tree is a motif present in several religions and mythologies, particularly Indo-European religions, Siberian religions, and Native American religions.
The world tree is represented as a colossal tree which supports the heavens, thereby connecting the heavens, the terrestrial world, and, through its roots, the underworld.
To understand this process we must first understand a little bit about the atoms themselves and how they get their names.
Most carbon atoms have six positively charged protons and six uncharged neutrons.
Other atoms are also named based on the number of protons they carry.
Notice in the diagram that eight different isotopes of Carbon are illustrated.
The branches of Yggdrasil extend far into the heavens, and the tree is supported by three roots that extend far away into other locations; one to the well Urðarbrunnr in the heavens, one to the spring Hvergelmir, and another to the well Mímisbrunnr.
Dendrochronology is an interdisciplinary science, and its theory and techniques can be applied to many applications. These research interests have in common the following objectives: Ring-counting does not ensure the accurate dating of each individual ring.
Scholarly theories have been proposed about the etymology of the name Yggdrasil, the potential relation to the trees Mímameiðr and Læraðr, and the sacred tree at Uppsala.
The world tree is also represented in the mythologies and folklore of Northern Asia and Siberia.
Numerous studies illustrate how ring-counting leads to incorrect conclusions drawn from inaccurate dating.
Dendrochronologists demand the assignment of a single calendar year to a single ring.
