Abstract
In the Big Bang Theory and the Black Hole Theory, the existing laws of physics all fail atthe singularity, and the singularity has become a blind spot in the existing scientific theories. In Cosmiccontinuum, the cosmic system collapse into a Schwarzschild black hole under the action of a stronggravitational field, and the Planck spheres at the center of the black hole continues to collapse into darkmass bodies, forming dark celestial body and singularity. The Schwarzschild radius is the upper limit ofa black hole, and the Planck sphere is the lower limit of a black hole. The singularity is the conversionpoint between the old and new cosmic systems. The singularity erupts the Planck spheres under theaction of a strong gravitational field, and the Planck spheres expands outward to form a new cosmicsystem. The Planck sphere is both the end of the old cosmic system and the starting point of the newcosmic system. The black hole collapse and the singularity eruption are mirror images of each other.The Planck sphere is the front of the mirror, and the singularity is the back of the mirror.
