This is usually considered to be the event horizon.

However a spinning black hole spinning fast enough or a charged black hole with high enough charge might not have an event horizon, leaving just what is called a naked singularity.

The boundary of a black hole is called the Event Horizon. It is, essentially, the point of no return.

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" you're probably thinking of is called the event horizon. Past this point, the escape velocity of the black hole exceeds the speed of light, meaning nothing, including light, can escape it.


What is the area beyond a black hole where black hole has stopped expanding and matter will no longer be pulled in?

There is no definite boundary for matter not being pulled toward a black hole. At large distances the effects of a black hole's gravity are not different from that of a different object of the same mass. How far out a black hole's gravity is dominant depends on that black hole's mass and its proximity to other massive objects.


Which of these have an event horizon giant black hole white dwarf neutron star?

An event horizon is the boundary beyond which nothing, not even light, can escape the immense gravitational pull of a black hole.


A black hole is a hole ripped in space through another sector in thin multi diminsianol place through time and space and gravity it then would a hole riped in space would stop light therefore stopping?

The term black hole is a misnomer that implies the notion of a hole; there is no hole, so there is no hole foe light to escape into another multidimensional place. A black hole is a spherical volume of immense gravitational attraction. The interface presented towards the outside world, called the event horizon is not really a physical boundary: it's merely the point beyond which not even light can hope to escape the gravitational pull of the black hole.

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.

Boundary near the center of a Black hole where no electronic radiation can escape is called the?

It's called the Event Horizon.


What happens when an object travels in speed of light through a black hole?

The object personally would disenigrate leaving only fair traces of it and that would be sucked up by the black hole on the edges because the center is the singularity or boundary.


How big is a super massive black hole km?

The size of a black hole is a meaningless quantity. The black hole itself, meaning the matter contained within, is infinitely small. However black holes can be defined by their schwartzchild radius which is the size of the event horizon. Look the equation for it up somewhere.
