One answer is that if it doesn't, we'll never detect it. But that's not a very good answer. A better answer involves the Higgs boson. Because the Higgs field gives mass to ordinary matter..." Current status of the Higgs boson decaying to invisible particles is, no such evidence has yet been found (2020): https://atlas.cern/updates/briefing/probing-dark-matter-higgs-boson https://atlas.cern/updates/briefing/probing-dark-matter-higg... This apparent failure (so far) of that hypothesis seems to have caused scientists in the field to cast around for other ideas, like primordial black holes: https://news.yale.edu/2021/12/16/black-holes-and-dark-matter-are-they-one-and-same https://news.yale.edu/2021/12/16/black-holes-and-dark-matter...
