Dark Matter is something producing regular gravity (bending spacetime in a way regular matter would) except we don't see the source, hence the name.

- dvfjsdhgfv 5y agoI 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.
- posix_me_less 5y agoThe 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.
- samatman 5y agoI like "subtle matter", personally. It isn't just light, as far as we know baryonic matter also passes through without interacting in any measurable way. It has certain... resonances with mystic traditions such as Theosophy, and I could see that being unwelcome in some circles. To my taste it's perfect.
