Tilted Forum Project Discussion Community - Experiment Where Scientists locate one atom in 10 Octillion

In the search for neutrinoless double beta decay, scientists at Stanford's Enriched Xenon Labs are trying to find a single atom in 10^28 atoms. Which is crazy.

Quote:

This means watching for an isotope of xenon decaying into barium, giving off two electrons (the double beta decay), but without giving out any neutrinos. A beta decay process gives off one neutrino, so how could this even be possible? It only works if the neutrino is its own antiparticle, so that the two beta decays each have a neutrino which essentially cancel each other out, like matter and antimatter annihilating. And the possibility that process exists is the reason for the experiment.
If neutrinoless double beta decay is observed, it means the neutrino must be its own antiparticle, a key unknown in the study of neutrinos. If the neutrino is indeed its own antiparticle, it has all kinds of implications for the structure of the Standard Model and the relationships between the fundamental particles.

Forgive me for nerding out, but this is really cool. Admittedly, I'm no physicist, but this experiment might change the way we look at elementary particle physics. That's a big deal.

Also, how often do we get to use the term "octillion" with impunity? Rarely.
