They came into existence violently… Born at the death of a massive star. They are are composed almost entirely of neutrons, barren of electrical charge and with a slightly larger mass than protons. They are quantum degenerates with an average density typically more than one billion tons per teaspoonful – a state which can never [...]

There are numerous papers on arXiv disputing the central contention of this article that quark matter stars do not exist (search the star's name), however that hypothesis does have the distinct advantage of being consistent with the complete lack of evidence for quark matter in the universe. If quark stars existed then they would sometimes be disrupted by interactions with black holes, releasing free quark matter.
