The commonly accepted 45 billion year age of the earth is derived from radiometric dating of lunar rocks and meteorites in addition to dating methods based on the gerling-holmes-houtermans model. The consensus view of scientists in relevant fields is that the age of the earth and the solar system is roughly 454 billion (454 × 10 9 ± 1%) years , an age primarily derived by radiometric dating. The dating of the meteorite impact events is one of the most intriguing aspects of this study, since it has application in determining the frequency of meteorite impacts both on earth and on the moon (baldwin 1971. Meteorites have also been dated by the sm-nd isochron method jacobsen and wasserburg (), for example, showed that 10 chondrites and the achondrite juvinas all fall on an isochron of 460 billion yearsthe results of radiometric dating on meteorites clearly indicate that these objects formed about 46 billion years ago. How do we know the earth is 45 billion years old radiometric dating provides an accurate method to know the age of the earth in 1896, the french chemist a henri becquerel discovered radioactivity, the process where materials decay into other materials, releasing energy.
Most people accept the current old-earth (oe) age estimate of around 46 billion years this age is obtained from radiometric dating and is assumed by evolutionists to provide a sufficiently long time-frame for darwinian evolution. It is largely based on radiometric dates from meteorites that are assumed to have formed at the same time as the earth there are also chemical arguments that indicate the pb (lead) in the earth separated from sources in the solar system at 454 billion years ago. Holmes published the age of the earth, an introduction to geological ideas in 1927 in which he presented a range of 16 to 30 billion years – a sufficiently accurate estimate for the time.
Nearly all meteorites have the same radiometric age, 456 billion years old 7 thus, the solar system, including the earth, is about 4,560,000,000 years old read more on scientific methods for determining the age of the earth. Scientists have also studied meteorites more than 70 meteorites have fallen to earth to have their ages calculated by radiometric dating the oldest of these have ages between 44 and 45 billion years. Radiometric dating measures the decay of radioactive atoms to determine the age of a rock sample it is founded on unprovable assumptions such as 1) there has been no contamination and 2) the decay rate has remained constant by dating rocks of known ages which give highly inflated ages, geologists.
This data is reproduced from dalrymple, the age of the earth note that 40 k also decays to 40 ca with a decay constant of 4962 x 10-10 yr-1, but that decay is not used for datingthe half-life is for the parent isotope and so includes both decays. Dating radiometric earth to according age of in addition, there is miles of solid rock dating presentation tips underneath the crust these are very few in comparison with the vast body of consistent enfp dating and relationships theological ideas in the past least 3. According to radiometric dating the earth is approximately 454 billion years old this age is based on dating of meteorite material. The age of the earth is known both by the ages of rocks gathered from other bodies in the solar system (eg meteorites and the moon) and also by knowing how old are the oldest rocks found on earth (the oldest date back to over 4 billion years.

Also, because earth formed as part of our sun’s family of planets – our solar system – scientists use radiometric dating to determine the ages of extraterrestrial objects, such as meteorites. The age of the earth is 454 ± 005 billion years (454 × 10 9 years ± 1%) this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples. Radiometric dating prior to 1905 the best and most accepted age of the earth was that proposed by lord kelvin based on the amount of time necessary for the earth to cool to its present temperature from a completely liquid state.
Radiometric dating techniques indicate that the earth is thousands of times older than that--approximately four and a half billion years old many christians accept this and interpret the genesis account in less scientifically literal ways. We know that earth’s age is up to 454 billion years, and also we know this calculation is based on radiometric age dating however, radiometric age dating is invented on beginning of the 20c. Young-earth creationism and radiometric dating young-earth creationist arguing in yec publications and church lectures that the earth is only 6000 years old according to those same rocks then extrapolates to tens of thousands of u-pb radiometric ages from all over the earth (and meteorites too) saying they have to be. The evidence for an old earth there are various scientific evidences for an ancient earth and/or solar system and universe (distance from the stars, speed of light, evidence from astronomy and physics, etc), but i will concentrate on the direct geological evidence: the material and rocks of the earth, the moon, and meteorites, and the various methods of radiometric dating that.
The late dr henry morris compiled a list of 68 uniformitarian estimates for the age of the earth by christian and secular sources17 the current accepted age of the earth is about 454 billion years based on radiometric dating of a group of meteorites,18 so keep this in mind when viewing table 6. Radiometric dating has been used to determine the ages of the earth, moon, meteorites, ages of fossils, including early man, timing of glaciations, ages of mineral deposits, recurrence rates of earthquakes and volcanic eruptions, the history of reversals of earth's magnetic field, and many of other geological events and processes. Researchers used uranium-lead techniques to date the meteorite back 454 billion years, give or take about 70 million — the best age for our planet so far, according to the us geological survey.
Yes, radiometric dating is a very accurate way to date the earthwe know it is accurate because radiometric dating is based on the radioactive decay of unstable isotopes for example, the element uranium exists as one of several isotopes, some of which are unstable. Of course, in the traditional view, the matter out of which the solar system was formed would have been very old at the start, in any event, and so the radiometric ages obtained from meteorites or from the earth do not necessarily tell us anything about the age of the solar system or the age of the earth. Andrew snelling concedes, radiometric dating of meteorites is solid figure 18 from snelling (2014) , illustrating the frequency of isochron ages obtained from the allende cv3 carbonaceous chondrite meteorite via six independent radioisotope systems (color coded, in legend.
