Most accurate form of radiometric dating
In fact, it is possible to shut down electron capture completely—simply ionize the substance so that there are no electrons nearby.There is a fairly well-known example of chemical state affecting electron capture activity.
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.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. "Decay" simply refers to a meson or baryon becoming another type of particle, as the number of a certain type of particle goes down or decays as they are converted.This can happen due to one of three forces or "interactions": strong, electromagnetic, and weak, in order of decreasing strength.Radiometric dating requires that the decay rates of the isotopes involved be accurately known, and that there is confidence that these decay rates are constant. The physical constants (nucleon masses, fine structure constant) involved in radioactive decay are well characterized, and the processes are well understood.Careful astronomical observations show that the constants have not changed significantly in billions of years—spectral lines from distant galaxies would have shifted perceptibly if these constants had changed.There are a number of implausible assumptions involved in radiometric dating with respect to long time periods.
One key assumption is that the initial quantity of the parent element can be determined.
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.
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.
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.
