Problems with scientific dating methods, the hourglass “clock”—an analogy for dating rocks
Evidence for the period of accelerated decay is found in zircon crystals. Some half-lives are listed below:. First, there would be massive contamination problemsas fluids, chemicals, and radioactive substances flowed or were carried from one place to another. These different layers can be deposited as particles of different size and density settle out of flowing water. By the same method we know the age of the earth from the histroy provided in the Bible, which is accurate and reliable.

Here are some of the most common radiometric methods: The assumptions on which the radioactive dating is based are not only unprovable but plagued with problems. Also, at the Flood there were catastrophic geological changes, see for example geological evidence for the flood and scientific evidence.
These basalts yield problems with scientific dating methods of up to 1 million years based on the amounts of potassium and argon isotopes in the rocks. It is, therefore, almost inevitable that our own measure of intelligence must reflect higher intelligences.
This was dealt with in the chapter by that name chapter 1. Because of such contamination, the less than year-old lava flows at Mt. Generally dating tips online chatting, the more complex a poem or piece of pottery is, the more advanced it is and the later it falls in the chronology.
Uniformitarianism is also challenged if we invoke the concept of a world-wide flood for which there is much evidence. To say that life originated in that seawater in some yesteryear "because the sand and seawater was there long enough " is just wishful thinking and nothing more.
Here are 12 factors which will be discussed in greater detail later in this chapter: These methods rely heavily on the assumption of uniformitarianism, i. Uranium dating is done by determining the amount of uranium and lead in a given sample, and then calculating how long it should take for a pure specimen of uranium, with no original lead in it, to decay to pure daughter lead--or to the amount of mixture ratio of uranium and lead that is in the sample.
How can we trust this method to tell us the age of rocks when the data do not match with observations? If these dates were true, they would seem to discredit the biblical account of a young earth of about 6, years. The problem is that strontium 87 is easily leached from one mineral to another, thus producing highly contaminated dating test results. Similarly, annual lake sediments can be used to estimate relative age and conventional interpretation for the Green River varves suggests they have been formed over some 20 million years. Part of the uranium and its daughter products could previously have leached out.
What about the radiometric assumption of constant decay rate? Since this would need a huge nuclear power source, it seems magnetic field decay places an upper age limit on the earth of the order of 10, years.
But unlike radiocarbon dating, the older the sample, the more accurate the dating — researchers typically use these methods on finds at leastyears old. However, this does not necessarily correlate to years because multiple rings can grow in one year.
Some claim a world-wide catastrophe may have occurred around 70, years ago, reducing the human population to maybe just 1, breeding pairs. Just what is time?
Every Issue. Every Year. 1845 - Present
But many or most such minerals might equally well contain some "radiogenic lead" lead still emitting radiation from some other source. That is how you know your age.
There is an obvious discordance disagreement in the data.
