This lightning talk explores groundbreaking exact solutions to Einstein's field equations that replace traditional black hole singularities with de Sitter cores and Hagedorn fluid. We examine three distinct solutions—static regular black holes with variable equations of state, configurations incorporating Hagedorn fluid under extreme conditions, and dynamic models showing transitions from regular to singular states during gravitational collapse. The presentation reveals how these theoretical frameworks align with Event Horizon Telescope observations of Sagittarius A* and discusses the profound implications for understanding real astrophysical black holes beyond General Relativity.
