In the context of a black hole, the boundary refers to the event horizon, which is the point of no return beyond which nothing, not even light, can escape the gravitational pull of the black hole. It marks the boundary between the observable universe outside the black hole and the region where all information is lost to the singularity at the center.

What is the unescapeable boundary of a black hole known as?
Event Horizon.
What is the name for the boundary around a black hole beyond which events cannot affect the observer?
The boundary around a black hole beyond which events cannot affect an outside observer is called the event horizon. Once an object crosses the event horizon, it is impossible for any information or signals to reach an outside observer due to the extreme gravitational pull of the black hole.
What is the OUTSIDE of the black hole called?
The very outside part of a black hole when "feeding" is called the Accretion Disc. when a black hole is not devouring a star the outside part becomes the Event Horizon.
What is the area beyond a black hole where black hole has stopped expanding and matter will no longer be pulled in?
The region beyond a black hole where it has stopped expanding and matter will not be pulled in is called the event horizon. Once matter crosses the event horizon, it cannot escape the gravitational pull of the black hole.
Gravity in a black hole is?
incredibly strong, leading to a region where not even light can escape, known as the event horizon. Objects that cross this boundary are consumed by the singularity at the center of the black hole.
What is a black hole's boundary?
its called the event horizon

What is the escape velocity at the boundary of a black hole?
By definition, the event horizon is a boundary of a black hole at which escape velocity reaches "c", the speed of light. Hence, the event horizon defines a boundary, within which, events can't affect an outside observer; neither light nor matter can escape.
Can you make a black hole inside a black hole?
We know nothing about the conditions within a black hole, but it seems unlikely that a black hole could exist within a black hole, or even if this concept would have any meaning at all.
What horizon is formed first?
The apparent horizon is formed first in the evolution of a black hole. It represents the point from which no light can escape, defining the boundary of a black hole's event horizon.
A collapsed star from which light cannot escape?
A black hole is a collapsed star with such a strong gravitational pull that not even light can escape from it. This phenomenon occurs when a massive star runs out of nuclear fuel and collapses under its own gravity. The boundary surrounding a black hole, beyond which nothing can escape, is called the event horizon.
What is the OUTSIDE of the black hole called?
The very outside part of a black hole when "feeding" is called the Accretion Disc. when a black hole is not devouring a star the outside part becomes the Event Horizon.
Boundary near the center of a Black hole where no electronic radiation can escape is called the?
It's called the Event Horizon.
What is the area beyond a black hole where black hole has stopped expanding and matter will no longer be pulled in?
The region beyond a black hole where it has stopped expanding and matter will not be pulled in is called the event horizon. Once matter crosses the event horizon, it cannot escape the gravitational pull of the black hole.

What is the difference between a black hole's photon sphere and its event horizon?
A black hole's photon sphere is the region around the black hole where photons can orbit in a stable circular path. The event horizon is the boundary beyond which nothing, not even light, can escape the gravitational pull of the black hole. In simpler terms, the photon sphere is where light can circle the black hole before falling in, while the event horizon marks the point of no return.
