Making Sense of the Patterns This three-part series will help you properly understand radiometric dating, the assumptions that lead to inaccurate dates, and the clues about what really happened in the past. Most people think that radioactive dating has proven the earth is billions of years old. Yet this view is based on a misunderstanding of how radiometric dating works. Part 1 in the previous issue explained how scientists observe unstable atoms changing into stable atoms in the present. Part 2 explains how scientists run into problems when they make assumptions about what happened in the unobserved past. When we look at sand in an hourglass, we can estimate how much time has passed based on the amount of sand that has fallen to the bottom. They also measure the sand grains in the bottom bowl the daughter isotope, such as lead or argon , respectively. Based on these observations and the known rate of radioactive decay, they estimate the time it has taken for the daughter isotope to accumulate in the rock. Conditions at Time Zero No geologists were present when most rocks formed, so they cannot test whether the original rocks already contained daughter isotopes alongside their parent radioisotopes.

## The Age of the Earth

This is very possible, and even likely. It is only an assumption that integral or adjacent lead could only be an end-product. In addition, there is “common lead, “which has no radioactive parent lead

Geochronology is the science of dating and determining the time sequence of events in the history of the Earth. This web page provides an overview of selected geochronology methods used by USGS scientists. New dating methods are invented all the time, however, most have practical limitations.

This age is obtained from radiometric dating and is assumed by evolutionists to provide a sufficiently long time-frame for Darwinian evolution. And OE Christians theistic evolutionists see no problem with this dating whilst still accepting biblical creation, see Radiometric Dating – A Christian Perspective. This is the crucial point: Some claim Genesis in particular, and the Bible in general looks mythical from this standpoint.

A full discussion of the topic must therefore include the current scientific challenge to the OE concept. This challenge is mainly headed by Creationism which teaches a young-earth YE theory.

## The Age of the Earth

It cannot date fossils and rocks and can only date objects that are a few thousand years old, not millions of years old. Radiological dating gives rather extreme age variation, and its interpretation requires many assumptions. The truth is that new scientific discoveries and radiocarbon dating prove that evolution is a hoax. Radiocarbon dating can only date an object that is about 30, or so years old.

Radioactive decay[ edit ] Example of a radioactive decay chain from lead Pb to lead Pb. The final decay product, lead Pb , is stable and can no longer undergo spontaneous radioactive decay. All ordinary matter is made up of combinations of chemical elements , each with its own atomic number , indicating the number of protons in the atomic nucleus. Additionally, elements may exist in different isotopes , with each isotope of an element differing in the number of neutrons in the nucleus.

A particular isotope of a particular element is called a nuclide. Some nuclides are inherently unstable. That is, at some point in time, an atom of such a nuclide will undergo radioactive decay and spontaneously transform into a different nuclide. This transformation may be accomplished in a number of different ways, including alpha decay emission of alpha particles and beta decay electron emission, positron emission, or electron capture. Another possibility is spontaneous fission into two or more nuclides.

While the moment in time at which a particular nucleus decays is unpredictable, a collection of atoms of a radioactive nuclide decays exponentially at a rate described by a parameter known as the half-life , usually given in units of years when discussing dating techniques.

Radioisotope dating shows the earth to be billions of years old. T38, 4: What We Really Know about Dating Methods When someone mentions scientific dating methods, the first thing to come to mind for most people is carbon dating. However, there are many methods that can be used to determine the age of the earth or other objects.

The Age of the Earth Strengths and weaknesses of radiometric and other dating methods. See also the discussions on Dating a Young Earth and Biblical Earth Dating.

This age is obtained from radiometric dating and is assumed by evolutionists to provide a sufficiently long time-frame for Darwinian evolution. And OE Christians theistic evolutionists see no problem with this dating whilst still accepting biblical creation, see Radiometric Dating – A Christian Perspective. This is the crucial point: Some claim Genesis in particular, and the Bible in general looks mythical from this standpoint. A full discussion of the topic must therefore include the current scientific challenge to the OE concept.

This challenge is mainly headed by Creationism which teaches a young-earth YE theory. A young earth is considered to be typically just 6, years old since this fits the creation account and some dating deductions from Genesis. The crucial point here is: Accepted Dating Methods Here we outline some dating methods , both absolute and relative, that are widely accepted and used by the scientific community. Absolute dating supplies a numerical date whilst relative dating places events in time-sequence; both are scientifically useful.

Radiometric Dating This is based upon the spontaneous breakdown or decay of atomic nuclei. Radioactive parent P atoms decay to stable daughter D atoms e. The time required for half the original number of parent atoms to decay is called the half life.

the radioactive dating of the earth’s rocks by geologists has supposedly proved that the earth is billions of years old. the radioactive dating method under heavy ‘fire’ The big surprise is that the attack has come from an evolutionary geologist and has been published in a secular scientific journal!

Dating techniques Photo by: Bastos Dating techniques are procedures used by scientists to determine the age of an object or a series of events. The two main types of dating methods are relative and absolute. Relative dating methods are used to determine only if one sample is older or younger than another. Absolute dating methods are used to determine an actual date in years for the age of an object.

Relative dating Before the advent of absolute dating methods in the twentieth century, nearly all dating was relative. The main relative dating method is stratigraphy pronounced stra-TI-gra-fee , which is the study of layers of rocks or the objects embedded within those layers. This method is based on the assumption which nearly always holds true that deeper layers of rock were deposited earlier in Earth’s history, and thus are older than more shallow layers.

## Radiometric Dating: Problems with the Assumptions

Radiometric dating, or radioactive dating as it is sometimes called, is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes.
