There have been proponents of the "dark matter is ordinary matter that's too cold to radiate light or infrared" theory, but such matter would also absorb light and betray its presence that way. So most cosmologists/astronomers argue that there must be another type of matter which does not interact with light at all (no electromagnetic force). It would be matter made of particles entirely unknown to us, and it would be far more plentiful than the kinds of matter we know. |
