"The power of waking is essentially 'the power to put sleeping hearts back the way they were.' But the impact of forcing his friends' fading hearts back the way they were rewrote reality, and created a singularity. The rewrite caused the chronology in which they were destroyed to have 'never happened.’”
Tetsuya Nomura
A singularity within science, mathematics, and technology, is a “point” where normal rules, equations, or physical laws completely break down. Let’s take a black hole for example: Classic physics states that when a massive star collapses, its entire mass is compressed into a geometric point of zero volume and infinite density. This point sits at the absolute center of a black hole. Hypothetically speaking, the Master of Masters could be this compressed star that metaphorically becomes a black hole which destroys everything.
