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 results from the Planck observatory satellite released in March 2013, is 13.798 ± 0.037 billion years. This improved measurement includes the data used for a 2006 measurement of 13.772 ± 0.059 billion years from the Wilkinson Microwave Anisotropy Probe.
Many fan-made timelines, such as Star Wars Timeline Gold, use references to Earth in the Star Wars canon to determine the time difference between the events in the films and the present day. Timelines which assume this time difference is only a few centuries or millennia often list 13,700,000,000 BBY or a similar date 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 speculative.
