Oldest thing found carbon dating, list of oldest trees

What is a forest, including developed soil and rooted stumps, doing between two advances of ice? It is painfully obvious that Dr. Another attempt by Morris invokes neutrinos.

Many of these trees may be even older than their listed ages, but the oldest wood in the tree has rotted away. Hovind adds the bizarre claim that something can't be measured accurately to seven decimal places. To put it another way, we might imagine a piece of buried wood as being something like a sponge. Sunspots have absolutely nothing to do with the rate of C decay, nany real world dating which defines the half-life of that radioactive element.

Whitelaw, using a greater ratio of carbon production to decay, concluded that only years passed since carbon started forming in the atmosphere! These changes are irrelevant to radiometric dating methods.

The point is that fluctuations in the rate of C production mean that at times the production rate will exceed the decay rate, while at other times the decay rate will be the larger. Through tree-ring cross-referencing, they have been shown to be more than five millennia old.

However, unless the sponge itself disintegrates, the carbon which holds its fibers together must stay put. Several factors, including the year sunspot cycle, affects its rate of decay. Judging from the above, it is easy to see that creationists are indulging in wild fishing expeditions.

The spike, or pulse, in carbon entered the marine food web across the North Atlantic no later than the early s. The interior portion of a tree trunk could easily be several hundred years older than the outer portions. This type of decay is electron capture e. Now, the fuller that barrel gets the more water is going to leak out the thoroughly perforated sides, just as more carbon will decay if you have more of it around. Various living samples give very different ratios.

Therefore, atmospheric variation in C production is not a serious problem for the carbon method. The shape of the curve of the line is based on too few real measurements to be reliable. We stick the garden hose in and turn it on full blast. We say that the input and output of water is in equilibrium.

So, there's no problem in getting an accurate decay curve. If you get your information from a creationist source, you'd better triple-check it! The marvelous agreement with tree-ring data, after correction for variations in the earth's magnetic field, has already been mentioned. Laboratories, of course, do have techniques for identifying and correcting contamination.

Because of background radiation, that's about as far as one can normally go with this counting method. The above is offered as a simple fact of research. In another creationist, Robert L. We can also explore this issue from first principles. Instead, estimates are made based on the tree's size and presumed growth rate.

Because of the chemical similarity of carbon and carbon, it is unlikely that such plants could deviate much from the ratio of C to C found in the atmosphere. Carbon is produced by energetic collisions between cosmic rays and molecules of nitrogen in the upper atmosphere. The notable exception involves certain mollusks, which get much of their carbon from dissolved limestone. Consequently, with regards to carbon dating, creationists are barking up the wrong tree on the contamination issue! The dipole moment of the earth's magnetic field, sunspot activity, the Suess effect, possible nearby supernova explosions, and even ocean absorption can have some effect on the carbon concentration.

Measurements of the decay rate of K in different substances under various conditions indicate that variations in the chemical and physical environment have no detectable effect on its e. The second table includes trees with these estimated ages. With that in mind, let's look at a few carbon dates.

Henry Morris chose not to mention that portion of the paper! That figure follows directly from the mathematics and, as the atmospheric portion of carbon given above is an approximation, is close enough to Dr. What the magnetic field does is to partially shield the earth from cosmic rays which produce carbon high in the atmosphere. The water level just sits there even though the hose is going full blast. That provides a useful time-stamp, says Nielsen.

We also have laboratory studies which support the constancy of all the decay rates used in radiometric dating. If he is referring to the carbon decay curve then he has demonstrated, once again, his ignorance of radiometric dating. Not every mollusk shell presents such problems, and the dating of other material might yield a cross-check.

Any carbon-containing liquid originally possessed by that sponge might well leak over time and be replaced by something else. That is, the limestone carbon skews the normal ratio between C and C found in living things.
