The Big Bang was the event that created the universe, an indeterminate amount of time prior to the formation of the galaxy. The galaxy's formation predates the formation of the Cularin system and the Yavin system, which would place the formation of the galaxy, and thus the Big Bang, some time prior to 7.5 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.
Behind the scenes
The age of our universe, according to current scientific consensus, is approximately 13.7 billion years. Many fan-made timelines, such as Star Wars Timeline Gold, use references to Earth in Star Wars canon to determine the time difference between the events in the films and the present day. Timelines which assume only a few centuries or millennia often list 13,700,000,000 BBY as the date of the Big Bang.
However, since neither Earth nor the Milky Way galaxy is mentioned in canonical Star Wars materials, such calculations are purely speculative.
