⊙, a "singularity of cosmology", is a kind of potential energy at the beginning of the universe, which was transformed into the mass and energy of cosmic matter by the Big Bang 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.
Space-a point in time with infinite curvature. Space-time begins there and ends there. Einstein said that time and space are illusions of people's understanding. Time is the change of everything in the universe, which gives people the concept of time. At the singularity, with the birth of the universe, change began, and this is the beginning of the universe. Classical general relativity predicts the existence of singularity, but because the existing theory fails there, it can't be described by quantitative analysis.
As the beginning of a world, 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 also imagine that at a certain moment, the potential energy balance of the singularity of the universe is broken, so energy is continuously transformed into matter, and a few years later, our universe-the * * * body of matter and energy is formed. However, we can't imagine what caused the potential energy balance of this singularity to be 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.
