Time explosion
A time explosion (TV: The Big Bang) or chronoclasm (AUDIO: Buying Time) was a destructive temporal phenomenon.
The Kovarian Chapter of the Silence caused the Eleventh Doctor's TARDIS to explode in 2010, which caused a total event collapse that destroyed every moment of the universe and causing cracks in time. (TV: The Pandorica Opens)
In the 41st century, George Sheldrake's misuse of the Nun's temporal velocitor to open time tunnels caused a chronoclasm where past, present, and future happened at once, and causality would eventually stop. Earth experienced dinosaurs, volcanos, Roman legions, Cavemen, Sabre-toothed tigers, Movellans, and spaceships all at once. Several Gorlans affected began to die, evolve, and devolve.
At the epicenter, it temporarily destroyed the Time Vortex, rendering time machines like the Nun's TARDIS inoperable, and although stabilising the explosion could restore the Vortex, the Tenth Doctor warned that the Nun tring to leave immediately could be lost forever. Because of the instability, the Doctor was able to pull his earlier self out of time (AUDIO: The Wrong Woman) from before the Last Great Time War. (AUDIO: Buying Time)
Similar to a time explosion, an event level chronal distortion could destroy a TARDIS, as it did when the Tenth Doctor collided with an Acari ship, splitting the fifth dimension in two and releasing huon radiation. (COMIC: Tesseract)
