Oldest distant quasar challenges universe formation theory
Astronomers Schmidt Gunn and Schneider report the discovery of a quasar formed at least 14 billion years ago, illuminating primordial gas. The find, set to be formally announced, suggests galaxies and stars emerged earlier and faster than Cold Dark Matter models predict, with the quasar about 18.5 billion light years away under a 20 billion year universe assumption.
