Big Bang Two

The Big Bang Two was an immensely awesome explosion caused by The Doctor in order to save every Universe from total annilhilation. In 1996, the entire Universe was collapsing due to The Doctor's TARDIS exploding and causing the Time Field. The Doctor used a Vortex manipulator and hooked it to the Pandorica, flying it into the heart of the explosion creating an explosion so powerful, it "rebooted" all of reality, closing all of the Time Fields forever. The Doctor had to be absorbed by it first but was revived on 26th June 2010 by Amy Pond's memory of him.
