Translation of this article.
The acronym for Static Detail Wave, or static matter wave.
In simple terms, this refers to [matter] itself. However, there we are talking about here refers to everything that gives form to the tridimensional space.
In other words, even things like the atmosphere are formed by SDWs.
All matter in this world is formed by waves. For example, iron would be a gathering of SDWs that have the FFT (frequencies) characteristic of iron.
