I always thought the name is quite sinister for this kind of mostly neutral (or even positive in the large scheme of things) phenomenon that we don't understand the nature of. We could give it a more interesting name like Barbēlō.
The name "dark matter" is bad, because matter that is dark absorbs a lot of light. Dark matter does not interact with light, light passes right through. It should have been called invisible matter, or non-electromagnetic matter.
