Novelty Theory suggests that on December 21 of 2012 AD, at the coincidence of the moment of the solstice and the heliacal rising of the galactic center, levels of planetary novelty will exponentially increase. Theory does not make clear the nature of the ultranovel event, however. Speculation as to the nature of the encounter with the trans-dimensional object at the end of time includes the following:

* Hyperspatial Breakthrough
* Planetesimal Impact
* Alien Contact
* Historical Metamorphosis
* Metamorphosis of Natural Law
* Solar Explosion
* Quasar Ignition at the Galactic Core
