The problem with fantasies is you can't really insist that everyone else believes in yours, the other problem with fantasies is that most believers of fantasies eventually get around to doing exactly that.Radiometric dating is a process of identifying the age of a material based on known half-lives of decaying radioactive materials found in both organic and inorganic objects.

In fact, radiometric dating can be used to determine the age of the Earth, (5.54 billion years old) other planets, and celestial objects.When an isotope decays, it often becomes a different kind of element altogether.Because this new element (decay product) remains on or within the object, scientists can easily determine how old the object is. A mass spectrometer is a fundamental device in any radiometric dating experiment.Mass spectrometers can be used to measure isotopic samples as small as one 1 nanogram.Mass spectrometers are made up of an ion generator, analyzer, and several detectors.The sample is ionized using the ionic generator and then passed through a magnetic field that separates the samples into different groups based on their mass and ionization levels.

When each ionized sample reaches the Faraday Cup in which it is stored, a current is produced and measured as an electrical signal.

A computer can then identify the types of atoms present in the sample as well as the number of atoms the sample has.

Radiometric dating is often referred to as “radioactive dating” and “carbon dating,” though many different types of isotopes can be used to identify an object’s age.

While not all objects have the same isotopes, both living and nonliving objects have some sort of decaying, radioactive isotope that can be used based on known decay rates. An isotope of some sort is located and isolated within an object.

That isotope is then compared to its decaying product and scientists are able to use known decay rates to determine how old the initial isotope is.

This works because elements have a life cycle known as a “half-life.” A half-life refers to the amount of time it takes for an isotope to lose half of its atoms as a result of decaying.

    My Facebook post from yesterday concerning a scouting camera photo of a 10 point Wisconsin buck generated an avalanche of responses regarding whether or not the deer was a “shooter”. Well, after reading the numerous responses, I’d have to say that opinions on the matter are pretty much equally split.
