What is needed to do radiometric dating
Hence, elements such as potassium, which has an average lifetime of nearly 2 billion years before decaying into argon, are useful for very long time scales, with geological applications such as dating ancient lava flows or Martian rocks.Carbon, on the other hand, with a shorter mean lifetime of over 8000 years, is more useful for dating human artifacts.In the case of carbon dating, it is not the initial quantity that is important, but the initial ratio of C, but the same principle otherwise applies.Recognizing this problem, scientists try to focus on rocks that do not contain the decay product originally.There is no reason to expect that the rate of decay of a radioactive material is largely constant, As early as of 1673, John Ray, an English naturalist, reckoned with alternative that "im the primitive times and soon after the Creation the earth suffered far more concussions and mutations in its superficial part than afterward". Atoms consist of a heavy central core called the nucleus surrounded by clouds of lightweight particles (electrons), called electron shells.The energy locked in the nucleus is enormous, but cannot be released easily.Historically, these are also known as alpha, gamma, and beta decays, respectively."Atomic decays" are due to proton or neutron decays: either weakly, incrementing up or down the table of elements; or strongly, often splitting into smaller elements, one of which is often helium.
However, the temperature required to do this is in in the millions of degrees, so this cannot be achieved by any natural process that we know about.However, the nucleus has a strong positive charge and the electron shells have a strong negative charge.Any incoming negative charge would be deflected by the electron shell and any positive charge that penetrated the electron shells would be deflected by the positive charge of the nucleus itself.Because radiometric dating fails to satisfy standards of testability and falsifiability, claims based on radiometric dating may fail to qualify under the Daubert standard for court-admissible scientific evidence.It is more accurate for shorter time periods (e.g., hundreds of years) during which control variables are less likely to change.
