<p>Create/expand category description</p> <p><b>New page</b></p><div>This category collects work concerning the &#039;&#039;&#039;Big Bang&#039;&#039;&#039; — the standard cosmological model, in which the universe began in a hot dense state some 13.8 billion years ago and has expanded since — and, for the most part on this wiki, criticism of it.<br /> <br /> See the main article [[Big Bang]].<br /> <br /> The objections catalogued here recur in a consistent set. They include: the horizon and flatness problems and the &#039;&#039;ad hoc&#039;&#039; character of the inflation invoked to solve them; the proliferation of unobserved entities — dark matter, dark energy — required to keep the model fitting observation; objects apparently older or more distant than the model permits; the interpretation of the cosmic microwave background; the anomalous redshifts and quasar associations documented by Halton Arp; and the methodological complaint that the model retrodicts more readily than it predicts.<br /> <br /> The principal alternatives represented on this wiki are steady-state and infinite-universe cosmologies, [[:Category:Plasma Cosmology|plasma cosmology]], and tired-light and other non-expansion readings of [[:Category:Redshift|redshift]].<br /> <br /> [[Category:Cosmology]]</div>
