speed is $$\frac{\text{distance}}{\text{time interval}}$$ but at the event horizon of a black hole, time interval becomes $0$. Imagine a flashlight flashes periodically 1 flash/s (in flashlight's reference frame). As flashlight getting close to the event horizon, someone far away from the event horizon will see flashlight flashing $0.1$ flashes/s, ...

As I know, Field Theory, that to what appeals the topic creator cannot explain the very powerful gravitation fields . So trying to understand what happens with a photon there are inside the Black Hole in meaning of Field Theory, or Special Relativity, isn't a good idea. The Nature has no the alone space , and the alone time , you can abstractly image ...

For better clarity, let's define the following: Axial direction = the direction the person & light beam are drawn into the BH. Radial direction = the direction perpendicular to the axial direction. If we, looking in the same direction as the person & light are being drawn into the BH, watch the light beam as it is drawn into the BH, we will see the ...

Now there is a light ray moving outward at the speed of light. I'm afraid that isn't the case; within the event horizon of a Schwarzschild black hole, the radial coordinate is timelike and so, moving 'outward' toward the horizon is as impossible as moving 'backward' in time. This plain to see in the Kruskal–Szekeres coordinates: Image credit See ...

I think a possible analogy would be to imagine that the singularity is a waterfall. By emitting light, you are trying to send a signal upstream using a tame fish. Outside the event horizon the fish is able to make headway against the current. But the river flows so fast within the event horizon as it approaches the waterfall, that your fish ends up going ...

How does light behave within a black hole's event horizon? It doesn't behave at all. If the event horizon of a black hole is the distance from the center from within which light cannot escape, imagine a person with a flashlight falls into the black hole. I've explored this with a variety of relativists, and posed this question. The answer comes ...

You can't "scootch the material from the event horizon" because in the coordinates of anything approaching the hole, the matter does in fact fall in. However, you could study for example radiation from the matter. This is thought not to resolve the paradox for several reasons (note I gave a very similar answer to Can the event horizon save conservation laws ...

My interpretation is that you are raising the following objection to the black hole information paradox: According to observers distant from the hole, causal lines take infinite coordinate time to cross the event horizon. To these observers, infalling information is thus never lost, but only very strongly redshifted; in essence it remains "painted" on the ...

A singularity is a hole, cut, rip or tear in a spacetime manifold. Any geodesics coming to it necessarily end there because the manifold ends there. In the worst case, the curvature resulting from the Schwarzschild solution tips all light cones inside the event horizon towards the singularity. Since all and any time-like geodesics and worldlines are bounded ...

Not exactly a swap, time becomes an imaginary number a square root of a negative number. "Formula The Schwarzschild radius is proportional to the mass with a proportionality constant involving the gravitational constant and the speed of light: $r_\mathrm{s} = \frac{2 G M}{c^2}$ where: rs is the Schwarzschild radius; G is the ...
