How does the general theory of relativity explain the speed of light being constant in a black hole?

The speed of light is constant in a black hole. How does the general theory of relativity explain it?|||The same way it explains the speed of light being constant outside of a Black Hole. The speed of light is the same, everywhere. The intense gravity inside of a Black Hole merely prevents light from leaving a Black Hole.


.|||Accodring to Einstein the strenghth of gravity of a collapsing star or a black hole distorts space and time ..Time is NOT a constant but relative to mass , electric charge and angular movement. C can not break away from the escape velocity past the event horizon as at this point time is outside of scientific observation of our universe in the event horizon IT IS SPACE THAT ALTERS NOT THE SPEED OF LIGHT A spinning black hole at the event horizon drags space and time so severly that it is impossible to stay in the same place This area is called the ergosphere it is not time we understand but that effect we can define as but not understand called gravity...


BUT TO YOUR QUESTION. a clock masures the proper time T(o )and a ruler measures the the proper distance L(o ) if the observer is so limited to quantify his observations due to the limits of the event horizon does this mean if it cant be observed, so it doesnt happen..so to the speed of light what distance are you measuring it against within the event horizon as space and distance is relative ... that is why it is relative to space and TIME|||It does no such thing, it never has and never will, black holes, like the "big bang" are points beyond which the laws are not understood in any rational way.








The term used by mathematicians, and physicists, alike, is "a singularity" it is literally a point beyond which no known methodology exists, for us to understand what the nature of the behaviour is like, within these conditions, and no way we can measure the behaviour either.








A point, if you like, where all mathematics breakdown, or are ineffective at describing or predicting the behaviour of the event, or object, in question.......everybody is simply guessing, incorrectly here,....... full stop.|||The theory of relativity is based around the assumption that the speed of light is constant in all reference frames (an assumption that has been shown in many experiments). Relativity doesn't explain why the speed of light is constant. The speed of light being constant explains relativity.|||It does not, there is no light in a black hole, light is trapped in the event horizon.
