In summary, light traveling through a black hole gravitational field is slowed down due to the increased distance and stretched time caused by the bending of space. This means that all light that enters the black hole will eventually reach the singularity and never escape. The Schwarzschild radius is defined by this feature.

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 traveling in.

So light traveling 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 Schwarzschild radius will never escape; it will curve toward and ultimately reach the singularity. I do believe that is the defining feature of the Schwarzschild radius.
 

FAQ: Light travelling through a black whole

How does light travel through a black hole?

Light cannot travel through a black hole because a black hole's gravity is so strong that it traps all matter and light. Once light crosses the event horizon of a black hole, it can no longer escape and is pulled into the singularity at the center.

Can light escape a black hole?

No, light cannot escape a black hole. The gravitational pull of a black hole is so strong that it traps all matter and light within its event horizon. This is why black holes are often referred to as "light traps".

What happens to light when it enters a black hole?

When light enters a black hole, it is pulled towards the center where the singularity is located. As it gets closer to the singularity, the light is stretched and distorted due to the extreme gravitational forces, and eventually it reaches a point of infinite density where it ceases to exist.

Can we observe light inside a black hole?

No, we cannot observe light inside a black hole because it cannot escape the event horizon. However, scientists can observe the effects of light on the edge of a black hole, known as the event horizon, which appears as a distorted, bright ring due to the bending of light by the strong gravitational pull of the black hole.

How does the gravitational pull of a black hole affect light?

The gravitational pull of a black hole is so strong that it bends and distorts light. This is known as gravitational lensing and it occurs because the intense gravity warps the fabric of space-time, causing light to follow a curved path around the black hole.
