Definition

It's bit unclear what this item is supposed to represent, but I think it's any "substance" composed of fundamental particles, including the individual particles themselves (since massless particles such as photons travel at the speed of light and don't really form "substances".) So I removed the statement that this item is a subclass of substance (Q27166344), since otherwise you get a subclass loop (see Wikidata:Project_chat#how_bad_are_loops_in_the_subclass-of_hierarchy?.
