Why is it not possible for light to escape a black hole?

Answer: Within the event horizon of a black hole space is curved to the point where all paths that light might take to exit the event horizon point back inside the event horizon. This is the reason why light cannot escape a black hole.

Is light the only thing that can escape a black hole?

No light of any kind, including X-rays, can escape from inside the event horizon of a black hole, the region beyond which there is no return. NASA’s telescopes that study black holes are looking at the surrounding environments of the black holes, where there is material very close to the event horizon.

Why can’t light travel through a black hole?

The escape velocity from within a black hole’s event horizon is faster than the speed of light, hence light cannot go at that speed and thus cannot escape. “”Even though photons have no mass, they are still affected by gravity.

What is the escape velocity of light from a black hole?

The Schwarzschild radius of a body smaller than rs is know as the event horizon of a black hole. At or inside the Schwarzschild radius, no geodesic can leave the black hole. Thus effectively the escape velocity is the speed of light. This means that nothing can leave a black hole, not even light.

How does a black hole affect the causal structure of spacetime?

5 Answers 5. Black holes affect the causal structure of spacetime in such a manner that all future light cones within a black hole lie within the event horizon of it. Although photons are massless they have energy and have to obey the geometry of a curved spacetime.

Are Photons trapped inside a black hole?

Although photons are massless they have energy and have to obey the geometry of a curved spacetime. Since all future lies within the event horizon, photons are trapped inside the black hole.
