Living Tree ‘8,000 Years Older Than Christ’ (?)

As I posted previouslyplanetary magnetic fields give us strong evidence for a young solar system and a young earth. Given that no old-earth theory comes close to doing this, it seems clear that from a planetary magnetic field standpoint, it is more reasonable to believe the earth and solar system are young than it is to believe they are old. Moving on, I would like to discuss the next set of data that leads me to believe in tree ring dating oldest young earth: This is just a fancy word for counting tree rings, and it probably represents the most reliable way to date things for which there is no historical date available.

This reasonably accurate dating method once again gives us strong evidence for a very young earth. In the spring, a tree does a lot of growing, since conditions are ideal for such activity. As a result, the new wood is not very dense. As spring turns to summer and summer to autumn, growth slows down. As a result, the wood becomes more dense. A typical turn of the seasons, then, produces light, not-so-dense wood followed by dark, dense wood.

This produces a visible ring. Tree ring dating oldest, in general, each year results in a ring. So if you cut down a tree, by counting the rings, you can determine how old the tree is:. So…how old is the oldest living tree? The oldest living tree called Methusalah has roughly 4, rings today 1. There was actually an older tree called Prometheusthat had roughly 4, rings when it was cut down in 2. Now you might think that the oldest living trees are the majestic sequoias, but in fact, these long-lived trees are the not-so-majestic Great Basin bristlecone pines, Pinus longaeva:.

Nevertheless, they are the oldest living things dated by dendrochronology. An interesting question now arises: How old can a bristlecone pine get? After all, we know of one living one that is just under 5, years relative vs absolute dating definition and one dead one that would be slightly older but still under 5, years old today.

Is that the limit? In fact, if the scientist who cut Prometheus down had any inkling that he was cutting down the oldest living tree, he never would have done it. Nevertheless, from all accounts I have read, Methuselah gives no indication of being anywhere near death. Why is it, then, that the oldest living tree is less than 5, years old, at tree ring dating oldest as far as dendrochronology is concerned? Since tree rings are formed by patterns of growth in a tree, individual tree ring dating oldest can tell us about the weather to which the tree was exposed during the year it was formed.

Thick rings, for example, are a sign tree ring dating oldest abundant rainfall and good growing conditions. Thin rings indicate poor growing conditions like not much rain, a very cool spring and summer, etc. So…a series of thick and thin tree rings denote a series of good and bad growing seasons. Often, there are distinct patterns of several good and bad growing years in a row. These patterns are called master tree ring patterns.

Then, suppose I find a fossilized tree that has that same pattern. However, because I know that the pattern of weather and thus the master tree tree ring dating oldest pattern started 3, years ago, I know that the part of the fossil tree with the master tree ring pattern is 3, years old. I can then count rings backwards from there to get more years. So…suppose there are 3, more rings inside the master tree ring pattern on the fossilized tree.

Now I have two trees speed dating auckland free, when the master tree ring patterns are overlapped, cover a total of 6, years. In other words, master tree ring patterns allow dendrochronologists to extend their dating further back than can be accomplished with just one tree.

As long as you can find enough fossilized trees with enough master tree ring patterns, you can extend a history of tree rings back across many trees. So…how far back can we extend tree ring histories? Well, probably the most reliable, unbroken tree-ring history goes back just over 11, years. Now these are upper limits, because it is possible for trees to grow multiple rings in one year 5. The tree ring dating oldest to do this is species-dependent, and the weather conditions required are reasonably rare.

Tree ring dating oldest, it does happen. If gymnosperms have been around for hundreds of millions of years, why do these chronologies extend only to a little over 10, years, which is an upper limit? Given the fact that tree rings indicate the oldest living tree to be about 5, years old roughly when you would expect the worldwide flood to have happenedand given the fact that the oldest tree ring chronologies which are upper limits extend only to a bit over 10, years, it is hard to believe that tree ring dating oldest kinds of trees have existed for hundreds of millions of years.
