Light travelling through a black whole

If light always travels in a straight line, the only time light appears to be bent is when a large gravitational field bends the space-time around it distorting the straight and time line the light is travelling in.

So light travelling through a black hole gravitational field would be slowed down in two ways. 1. The distance it would have to travel would be greatly increased by the bending of space. 2. Time is also stretched increasing the time it will take to travel thought the space.

Dose this mean that light can always escape a black hole but just takes a very long time to do so? An only light that doesn’t come out of the black whole is the light that hits the singularity.

I apologise if any of this is spelt wrong, I am dyslectic and I think everything is spelt right.

Your second sentence essentially gives the answer - all light ends up at the singularity.

Appears to be bent? It is bent. No one would say the path of the Earth only appears to be bent...

All light that crosses the Schwarzchild radius will never escape; it will curve toward and ultimately reach the singularity. I do believe that is the defining feature of the Schwarzchild radius.
