The scenario you described, where a black hole is created from the destruction of an entire universe, falls beyond our current understanding of physics and cosmology. It ventures into the realm of speculative concepts and hypothetical scenarios.
Black holes are formed when massive stars collapse under their own gravitational pull, condensing into an extremely dense object with a gravitational field so strong that nothing, not even light, can escape its grasp. However, the creation of a black hole from the destruction of an entire universe would involve processes and phenomena that are purely speculative and not supported by our current scientific understanding.
Our understanding of black holes is based on the physics of our universe, and we do not have a comprehensive theory that can explain the behavior or consequences of black holes on a scale larger than a single universe. Speculating on what would happen to matter in such a scenario would be purely speculative and speculative.
It's important to note that the nature and behavior of black holes are still active areas of research in astrophysics and theoretical physics. Scientists continue to study and investigate these cosmic phenomena to deepen our understanding of their properties and their implications for the universe we observe.
