Spiral Nemesis

The Spiral Nemesis (スパイラル・ネメシス, Supairaru Nemeshisu?) is a theoretical event which the Anti-Spiral race are fighting to prevent. It would theoretically occur when Spiral Energy evolves beyond a certain point. As the Anti-Spiral themselves explain it, the evolution of life would lead to a loss of control of Spiral Power, which had already shown throughout the series to ignore the law of conservation of mass (IE: creating matter from nothing, from Giga Drill Breaks to the transformation of the higher levels of Gunmen), and all life forms in the universe evolving into full-sized galaxies spontaneously. The sudden imbalance of mass in the universe would lead to these mega-galaxies devouring each other, forming a black hole, and the universe returning to nothingness. This is the Spiral Nemesis, the theoretical event that the Anti-Spiral destroyed so many Spiral races to prevent from ever occurring.

Of course, in The Lights in the Sky are Stars, it is shown that the Spiral Nemesis is more than theory. When Super Tengen Toppa Gurren Lagann and Super Grand Zamboa's Giga Drill Breaks collide, the entire Anti-Spiral universe begins to collapse into itself. Of course, this was on an order of Spiral Power magnitude far greater than even the Anti-Spiral thought the Spiral races were capable of. The Spiral Nemesis, while possible, requires a great deal more mass and Spiral Power than the Anti-Spiral had initially surmised.

Note: This page needs more information on the following: Is the Spiral Nemesis really inevitable? If it is inevitable, does it mean that all spiral evolution will terminate at a singularity that will destroy everything for eternity? Does this mean that spiral races must exercise caution in its usage? Conversely, will causing the Spiral Nemesis cause another Big Bang to occur, thus resetting history? If it is not inevitable, then were the Anti-Spirals simply mistaken or abusing this knowledge?

Note 2: None of these questions were answered in the series. All information answering the above questions would be pure speculation.
