I am a bit confused at the idea that information cannot be sent out from behind the event horizon of a black-hole. Consider the following figure: (source This link)
An apple thrown up from the surface of the earth can go up and come down if thrown below the escape velocity. If I throw an apple fast enough (but below the escape velocity), someone sitting on the moon can also catch it and extract information from it.
So what if Bob falls into a black hole and throws an apple incredibly fast (or shines a light beam) up towards an orbiting spaceship, just as he crosses the event horizon, is it not conceivable that Alice in the spaceship can catch the apple (or the beam)?
Since the escape velocity at the event horizon is that of light, it only implies that for any object to go infinitely far it must be moving at the speed of light. This does not imply that an object thrown slower cannot move up a finite distance before falling back.
Therefore, would not an apple thrown fast enough be able to reach an astronaut orbiting the black-hole from a safe distance?
