In the Big Bang Theory and the Black Hole Theory, the existing laws of physics all fail at
the singularity, and the singularity has become a blind spot in the existing scientific theories. In Cosmic
continuum, the cosmic system collapse into a Schwarzschild black hole under the action of a strong
gravitational field, and the Planck spheres at the center of the black hole continues to collapse into dark
mass bodies, forming dark celestial body and singularity. The Schwarzschild radius is the upper limit
of a black hole, and the Planck sphere is the lower limit of a black hole. The singularity is the
conversion point between the old and new cosmic systems. The singularity erupts the Planck spheres
under the action of a strong gravitational field, and the Planck spheres expands outward to form a new
cosmic system. The Planck sphere is both the end of the old cosmic system and the starting point of the
new cosmic 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.
