WebAug 1, 2024 · Rather, it either remains at a finite radius until the outer horizon meets it or has an evolution of its own which must be analysed. The former of these two possibilities represents the smallest deviation from Hawking’s paradigm, having a long-lived external horizon, but avoiding the formation and subsequent “evaporation” of a singularity. WebYou can think of the event horizon as being the distance from a black hole at which the escape speed is the speed of light, 3.00 × 108 m/s, making all escape impossible. What is the radius of the event horizon for a black hole with a mass 5.0 times the mass of the sun? This distance is called the Schwarzschild radius.
