I clarify my question: beyond the event horizon of a black hole, according to general relativity, the space-time flows faster than the speed of light. If it is the case, then, no information can be transmitted from here.

But then, if i drop an apple, say, in the black hole.

The black hole would then gain mass, and i could theorically mesure that gain with the event horizon radius variation and the attraction, meaning that the information of its mass and attraction change went from the center to get out of the event horizon.

In other words, that gravity information would have been faster than light?

How is that possible and where did i not understand something? (Just daydreamed about this stuff so maybe my question in itself is idiotic, sorry physicists)
