Xenotron

An Xenotron was the smallest known particle in existence. Xenotrons are so small that they travel through the tunnels of quantum foam itself. They are not known to the 3rd dimension, which knows nothing smaller than quantum foam. Their height and width are both one xenometre, a unit of measurement named after them. One xenometre is an incomprehensible amount of times shorter than a yoctometre. Because it can not be broken up into anything smaller, it cannot be destroyed.
As of 71007 AD, 19 eons AR it has been confirmed that there is an even smaller particle.
