The Oldest Living Thing: The oldest living thing on earth is either an Irish Oak or a Bristlecone pine. If we assume a growth rate of one tree ring per year, then the oldest trees are between 4, and 4, years old. Also, with regard to fossil tree rings, the author has been unable to find any documented instances of fossil trees having more than about rings. This is significant since we are told that God literally made the Earth, and all that is in it, only about years before the Noachian Flood described in the Book of Genesis. In a Bristlecone Pine tree was discovered that has just over 5, tree rings. Helium in the Atmosphere: Helium is a byproduct of the radioactive decay of uranium as it decays into various different elements into its final stable element: As it decays, the helium not only accumulates in the rocks themselves, but also escapes from them and accumulates in the earth’s atmosphere. They also know how much helium is currently in the atmosphere.
Age of the Earth
Diversity of beliefs about the age of the Earth By old-Earth creationists, young- Sponsored link. There is a great diversity of belief concerning the age of the Earth and the rest of the universe:
The generally accepted age for the Earth and the rest of the solar system is about billion years (plus or minus about 1%). This value is derived from several.
Methods of Dating the Age of Meteorites Meteorites are among the oldest objects we know about – formed about 4. But how do scientists know this? This article describes the principles and methods used to make that determination. There are well-known methods of finding the ages of some natural objects. Trees undergo spurts in growth in the spring and summer months while becoming somewhat dormant in the fall and winter months. When a tree is cut down, these periods are exhibited in a cross section of the trunk in the form of rings.
Simply counting the number of rings will give one a fairly good idea of the age of the tree. Periods of heavy rain and lots of sunshine will make larger gaps of growth in the rings, while periods of drought might make it difficult to count individual rings. When determining the ages of very old objects, the only suitable clocks we have found involve the measurement of decay products of radioactive isotopes.
Isotopes are atoms of the same element with different amounts of neutrons. Some isotopes are stable, whereas others are radioactive and decay into other components called daughter isotopes.
The way it really is: little-known facts about radiometric dating
Reference to a case where the given method did not work This is perhaps the most common objection of all. Creationists point to instances where a given method produced a result that is clearly wrong, and then argue that therefore all such dates may be ignored. Such an argument fails on two counts: First, an instance where a method fails to work does not imply that it does not ever work. The question is not whether there are “undatable” objects, but rather whether or not all objects cannot be dated by a given method.
The fact that one wristwatch has failed to keep time properly cannot be used as a justification for discarding all watches.

And though you’d think they would have fewer problems than us mere mortals in finding a significant other, apparently they suffer the same slings, arrows and bad dates as the rest of us. They are not the kind of guys who go on on “Millionaire Matchmaker. Men make up the majority of a high end matchmaker’s clients. Women are generally not the clients but potential matches for the men; and in most cases, they simply pay an application or interview fee. I don’t think this is any sexist plot by the modern day Dolly Levi’s, only a reflection of a dating dynamic that is still alive and well — at least where well-to-do men are concerned.
Though New York based, all work with clients across the country and internationally , and Daniels keeps an LA office as well. All offer a unique perspective and approach to their services, and all have toe-curling prices. How much will this set a guy back? This will give you a year to 18 months of matches. Matchmaker Richard Easton, new to the New York market and an anomaly among matchmakers — most are women — says he challenges the price resistance he sometimes encounters with a car analogy.
The Age of the Earth
Problem solving using the half-life of a radioisotope or radioactive emission data to work out the half-life of a radioactive isotope. What is the half-life of radioactive isotopes? What is a radionuclide decay curve?
It would probably be an understatement to say that dating is an important part of a teenager’s life. In one study, researchers found that high school students consistently rated the time spent alone with an opposite-sex partner as the time when they were happiest and most satisfied with life. Therefore, as parents, how can you [ ].
The Radiometric Dating Game Radiometric dating methods estimate the age of rocks using calculations based on the decay rates of radioactive elements such as uranium, strontium, and potassium. On the surface, radiometric dating methods appear to give powerful support to the statement that life has existed on the earth for hundreds of millions, even billions, of years. We are told that these methods are accurate to a few percent, and that there are many different methods.
We are told that of all the radiometric dates that are measured, only a few percent are anomalous. This gives us the impression that all but a small percentage of the dates computed by radiometric methods agree with the assumed ages of the rocks in which they are found, and that all of these various methods almost always give ages that agree with each other to within a few percentage points.
Since there doesn’t seem to be any systematic error that could cause so many methods to agree with each other so often, it seems that there is no other rational conclusion than to accept these dates as accurate. However, this causes a problem for those who believe based on the Bible that life has only existed on the earth for a few thousand years, since fossils are found in rocks that are dated to be over million years old by radiometric methods, and some fossils are found in rocks that are dated to be billions of years old.
If these dates are correct, this calls the Biblical account of a recent creation of life into question. After study and discussion of this question, I now believe that the claimed accuracy of radiometric dating methods is a result of a great misunderstanding of the data, and that the various methods hardly ever agree with each other, and often do not agree with the assumed ages of the rocks in which they are found.
I believe that there is a great need for this information to be made known, so I am making this article available in the hopes that it will enlighten others who are considering these questions. Even the creationist accounts that I have read do not adequately treat these issues. At the start, let me clarify that my main concern is not the age of the earth, the moon, or the solar system, but rather the age of life, that is, how long has life existed on earth.

High-End Matchmakers Dish on Dating
Leibnitz reworked Descartes’s cosmogony. Protogea was published much later in An essay toward a Natural History of the Earth.
March 28, This post is about elevation measurements for exposure-dating samples, and how accurate they need to be. Basically, the main thing that controls cosmogenic-nuclide production rates is site elevation, or, more precisely, atmospheric pressure — at higher elevation, there is less atmosphere between you and the extraterrestrial cosmic-ray flux, so the production rate is higher.
Thus, to compute the cosmogenic-nuclide production rate at a sample site, the first thing we need to know is the elevation. Once we know the elevation, we can convert it to a mean atmospheric pressure using a model for how the atmospheric pressure varies with elevation, and then compute the production rate. The second one — converting an elevation to a mean atmospheric pressure during the exposure duration of the sample — is actually a fairly complicated problem and is the subject of another post , as well as a fairly large number of papers.
However, the first one — accurately measuring the elevation — ought to be pretty simple. In general, determining your elevation is a fairly well-established technology that people have been working on for centuries. So the rest of this post covers i exactly how precise we need elevation measurements to be, and ii various ways to accomplish or not accomplish that goal. So how precise do we need elevation measurements to be? Basically, the point of all this is that we would like to be able to measure elevations with better than 10 m precision.
Preferably quite a lot better.
