What is the term for the boundary of a black hole beyond which nothing can escape?
Answer
Event horizon
The event horizon is the point of no return around a black hole. Once something crosses this boundary, it cannot escape, not even if it travels at the speed of light.
💡 Did you know?
The event horizon of a black hole grows as it consumes more matter, making it a cosmic vacuum cleaner of sorts.
