Muons are constantly being created as cosmic rays collide with molecules in Earth's upper atmosphere. With their ability to penetrate far into dense, solid materials, these cosmic muons are often used to image the insides of objects that are otherwise hidden from view. However, the flow of these natural particles is far too slow for the technique to become both fast and reliable in practical settings.
