Cosmic singularity, as a kind of "cosmic singularity", is the point where the universe exploded at the beginning and formed now. It has the potential energy of all matter, and this potential energy-the mass and energy transformed into cosmic matter by BIGBANG, and the "space" to express this mass and energy. We can imagine that singularity is an invisible, infinitesimal and wonderful existence. It is not the universe yet, but it is the origin and origin of our universe. As the beginning of a world, it should have all the potential energy that constitutes all the substances in the universe, and this potential energy-what we call energy-we can imagine that energy is an invisible thing, so the singularity is invisible. In other words, the potential energy of the singularity of the universe is invisible, it is just a wonderful existence. At the same time, we can imagine that this potential energy balance of the singularity of the universe is broken at some point. As a result, energy is constantly transformed into matter, and a few years later, our present universe-a * * * living body of matter and energy-is formed. However, what we can't imagine is that the potential energy balance of this singularity is destroyed. Singularity is a "geometric point" with no size, that is, a point that does not actually exist, which is very difficult to understand. It is also difficult to understand that strange matter without size is actually a matter with infinite energy level. These are inconsistent with our existing theories and concepts.
