That last bit is important during “beta decay”, which is the type radioactive decay that the Weak force is involved in.
A muon and an electron neutrino exchange a W boson (carrying a negative charge, and some momentum), which changes the muon into a muon-neutrino and the electron-neutrino into an electron. Far more common is muon decay, but that doesn't demonstrate the point.
All rocks and minerals contain long-lived radioactive elements that were incorporated into Earth when the Solar System formed.
To accomplish this, scientists use a variety of evidence, from tree rings to the amounts of radioactive materials in a rock.
In regions outside the tropics, trees grow more quickly during the warm summer months than during the cooler winter.
Gluons can also cause the involved particles to change, specifically switching protons and neutrons.
However, if you start with one neutron and one proton, and you end with one neutron and one proton, what’s the difference?
In other words, you can use superposition to tell you that one rock layer is older than another.
But determining the absolute age of a substance (its age in years) is a much greater challenge.The big difference is that the other force carriers; photons, gluons, and (if they exist) gravitons, leave the involved particles alone (other than energy and momentum). While the Weak force can mediate interactions between particles without changing them (this is a result that helped point the way to the discovery of the “electroweak force”), it can also carry stuff with it, like charge.By taking charge from one thing, and giving it to another, it’s changed the particles involved.These tree ring variations will appear in all trees growing in a certain region, so scientists can match up the growth rings of living and dead trees.Using logs recovered from old buildings and ancient ruins, scientists have been able to compare tree rings to create a continuous record of tree rings over the past 2,000 years.In addition to the ages of Earth, Moon, and meteorites, radiometric dating has been used to determine ages of fossils, including early man, timing of glaciations, ages of mineral deposits, recurrence rates of earthquakes and volcanic eruptions, the history of reversals of Earth's magnetic field, and the age and duration of a wide variety of other geological events and processes.Tags: Adult Dating, affair dating, sex dating
