Dimensional Explosion
From The Monoverse: A Non-Linear Sci-Fi Epic
A Dimensional Explosion is a type of Dimensional Decay that is a rapid decay. Essentially a Dimension ceases to exist within a short amount of time, and may or may not affect other dimensions around it after it "explodes." Dimensions can also implode, but they are generally referred to as an explosion, since it may be hard to actual judge whether or not other dimensions are affected.
