In field and string theory, we demonstrate a link between ultra-Planck a scattering amplitudes and unitarization via black hole creation in these scattering processes. We were able to identify and calculate a set of perturbative amplitudes important for black hole creation using an explicit microscopic theory in which the black hole represents a bound-state of many soft gravitons at the quantum critical point. In a kinematical regime (called the classicalization limit), these are the tree-level N-graviton scattering S-matrix elements where the two entering ultra-Planck and gravitons generate a huge number N of soft gravitons. The Kawai–Lewellen–Tye relations, as well as scattering equations and string theory methods, are used to calculate these amplitudes. This limit exposes the essential characteristics of the tiny corpuscular black hole N-portrait, according to our findings. When N approaches the quantum criticality value, the perturbative suppression factor of an N-graviton final state, calculated from the amplitude, equals the non-perturbative black hole entropy, while non-perturbative corpuscular physics suppresses or excludes final states with various values of N. As a result, we've discovered the microscopic cause for black holes' supremacy over alternative final states, such as non-black hole classical objects. The scattering equations can be solved precisely in the parameterization of the classicalization limit, enabling us to get closed formulas for the high-energy limit of the open and closed superstring tree-level scattering amplitudes for a generic number N of external legs. In various large-s and large-N regimes, we show that string theory and field theory are compatible and complementary.
