Outline:

Thesis statement: Is Radiometric Dating truly factual or merely a fallacy?

The age of the universe is a well questioned topic. Some believe that the universe is billions of

years old, whilst others object, and state that the universe is less than a decade old. But, how can

the difference in beliefs be so drastic? This paper will include topics such as, the method of

Radiometric Dating, the Christian belief, problems between both beliefs, how Radiometric

Dating has been dubbed ineffective, and in the end will raise …show more content…

Which means that all organisms, plants and animals,

have a certain amount of radioactive carbon-14 held within their system. When alive, the levels

stay the same and is stable. But when the organism becomes deceased, the levels of carbon-14

halts, and as time passes by, the levels decrease and decay in the organism, which gives us

Radioactive Decay (Connor). ?The technique of carbon dating was suggested initially by Willard

Libby and his colleagues in 1949? (Connor).

Another method is Potassium-Argon Dating. This method uses potassium-40, an

exceedingly rare isotope, and isotope argon-40, a reaction from the decay of potassium-40.

Potassium has a half-life of 1.25 million years, so it is much better for dating things (Khan).

Also, some calcium-40 but it's not focused on. Potassium-Argon Dating is a method used to date

old rocks and fossils (Khan). For example, a volcano erupts and potassium-40 and argon-40 are

present in the lava. The argon-40 is a noble gas so it would seep out of the liquid lava because …show more content…

Carbon-14 has been detected in many natural organisms and it dates then back

millions to billions of years old. But carbon-14 shouldn't be detected in any organic matter that?s

older than 100,000 years (Herbert). Once an organism becomes deceased, it stops taking in

carbon-14 and the isotope begins to decay (Herbert). Fortunately, a recent analysis of one of the

assumptions of these systems being used, had to be re-evaluated. Gregory Brenneka of ASU and

others, measured the relative amounts of Uranium 235 and Uranium 238 in an Allende meteorite

(Thomas). They found slight differences in the isotope ratios from samples of the same

meteorite. This discovery was unexpected and it made people question what the age of things

truly are. ?A critical assumption used in carbon-14 dating has to do with this ratio. It is assumed

that the ratio of 14C to 12C in the atmosphere has always been the same as it is today (1 to 1

trillion). If this assumption is true, then the AMS 14C dating method is valid up to about 80,000

years. This is a critical assumption in the dating process. If this assumption is not true, then

There are various scientific techniques when examining an ancient body. When Tollund man was first excavated in Denmark 1950, scientists were limited in the amount of analysis methods available. The first dating method used on Tollund man was pollen analysis, this scientific method would only bring a small time frame as to when he lived. Instead forensic scientists were prompted to use radiocarbon dating. Radiocarbon dating is conducted by measuring the levels of radioactive isotope carbon-14 in Tollund man's body.

Although this hypothesis is widely accepted by the scientific community, James B. Benedict wanted to determine whether wind could be the potential cause of charcoal in the alpine fellfield ecosystem. In order to do this, he analyzed fifty-six soil samples collected from shallow depths in the Front Range of Colorado. He compared these samples to other samples collected in the alpine fellfield region, which is at a higher elevation. The results of analyzing shallow soil cores from fifty six regions revealed that the charred particles were discovered to be bigger and more numerous in the subalpine forest with a sharp decrease directly above the tree line that marks the start of the alpine fellfield ecosystem but no further decreases. The presence of large charcoal particles, which are the result of local fires, in Front Range tundra suggests that windblown forest fire charcoal can contaminate AMS radiocarbon samples from high elevation archaeological sites.

There have been experimental pits dug around the tomb but the tomb itself has never been excavated. By looking at the Roman Catacombs, it is seen that the past influences modern day activities. Relative dating does not provide actual dates for objects, although it can be used to arrange geological events. Through looking at strata it is able to look at timeline events and arrange them chronologically.

INTRODUCTION The Cretaceous Period, spanning 65.5-146 million years ago (Mya), was a world different from what we are familiar with today. Planetary changes during this period included the extinction of dinosaurs and drastic global warming. The breakup of the super continent Pangea had started about 30 Mya, and seaways had begun to form and cover landmass that had once been a part of the super continent (Geologic Time). Today, scientists know that one of these landmasses, the North American continent as we now know it, was at one point covered by a vast inland sea known as the Western Interior Seaway.

Another factor that could have skewed the results is a picture captured of the scientists the day of the exposition. In this picture, the scientists were taking samples near a burn and watermark. Since the nuns replaced the damaged pieces of the shroud, the scientists could have possibly been testing fabrics that are more modern (“Shroud of Turin”). Over the years, damp stains became noticeable and someone could have possibly washed or cleaned the linen. The question stands if the later years of the cloth could have contaminated the carbon 14 test to give the incorrect

When reading in chapter 9 about “Geology and Primate Origins”, I came to a decision to choose the relative dating techniques. It is dating techniques that establish the age of a fossil only in comparison to other materials found above and below it. Relative dating techniques use the principles of stratigraphy to tell us how old something is in relation to something else without applying an actual chronological age. An example of this technique is biostratigraphy (faunal correlation), biostratigraphy is a relative dating technique using the comparison of fossils from different stratigraphic sequences to estimate which layers are older and which are younger; employed in the Early Pleistocene deposits at Olduvai and other African sites. The prime

Complex exothermic reactions result in a large variety of carbon isotopes where some of the carbon will react with oxygen to create carbon monoxide and a lower number isotope of carbon. Over time the carbon dust grains cluster together and form carbon grains. Particles observed in meteorites tend to be large ranging from 0.8 to 20 micrometers

Every year, it captures sediments such as dust and sea salts. It can even collect human pollutants. If we know what each layer of ice counts for in years, we can figure out the average temperature per year and see any recent climate events, such as a volcanic eruption. This technique is called dating.

This point is valid to a certain extent, after it was released to the public that the shroud was a fake many tried to disprove this by coming up with theories that explain the reasoning for the dates being so late. Joe Marino and Sue Bedford were a couple who like many others had doubts about the results of the carbon tests. After years of playing detective the couple believed that they had finally found a logical explanation as to why the carbon dating produced such a late creation date. Their theory stated that the scientists working on the shroud had taken a piece of fabric that had been restored with a special technique that blended the two different sections together, consequently the date of the test was
