Big Bang

The Big Bang was the event that created the universe, an unknown amount of time prior to the formation of the galaxy thirteen billion years before the Battle of Yavin.

The Shawken Device was designed to cause a chain reaction that would destroy all star systems in the existing universe, with the purpose of eventually triggering a new Big Bang to begin the universe again. While this exact outcome is questionable, the effects produced by this superweapon could have still been disastrous had it ever been given a chance to destroy the planet Shawken, where it was located.
