Seems likely to me that "dark matter" is just the latest catch-all for theorical numbers not matching reality. There is a rich history of science postulating a McGuffin until a stronger theory comes along and I see no reason that some untrackable "dark matter/energy" actually exists. Not so long ago light used to travel through the "aether". Before we knew of germs, we blamed the "miasma". Something that has form but no detail needs a name but it is key to not rely on vaguely formed concepts as a legitimate answer.
