Chapter 34: Q16CQ (page 1237)

Is the event horizon of a black hole the actual physical surface of the object?

Short Answer

Expert verified

It isn't, however it is necessary for comprehending how black holes function.

Step by step solution

01

Step 1:Definition of black hole.

The existence of black holes, objects for which the escape velocity is greater than the speed of light and from which nothing can escape.

02

Finding whether event horizon of the black hole in actual surface of object?

The event horizon is a theoretical construct that is important in understanding black hole dynamics. In the same manner that an open door represents a surface, the event horizon does as well. You can plainly determine where the door was since you can see the "door surface," but you can also pass it because there is no hard physical boundary.

The event horizon is intriguing because once crossed, it is impossible to return, much like a door that is open on one side but locked on the other.
