Webgravitons, when the massive graviton is generated, the massless graviton is also generated. Massless gravitons would then be observed as a gravitational wave back-ground. Therefore, if the massive graviton in bigravity is dark matter, the gravitational wave background can carry information about dark matter. As an example, we assume WebDark matter definition, a hypothetical form of matter invisible to electromagnetic radiation, postulated to account for gravitational forces observed in the universe.
