Hermitsisia
Hermitsisia is a theoretical astronomical phenomenon that describes the potential for a solitary star, devoid of any stellar companions, to eventually evolve into a black hole. Unlike stars in binary or multiple star systems that can interact gravitationally and influence their evolutionary paths, a hermitsisia star would proceed through its life cycle in isolation. The primary mechanism for a star to become a black hole is through the process of gravitational collapse after exhausting its nuclear fuel. For stars of sufficient mass, typically exceeding 20-25 solar masses, the outward pressure from nuclear fusion can no longer counteract the inward pull of gravity.
In the case of a hermitsisia star, this collapse would occur without any external gravitational perturbations
