event horizon - Information encoded on the surface of a black hole


If an object that enters a black hole has its information content frozen at the event horizon, in what sense is it frozen? The usual analogy is of a hologram encoded in 2d which can be decoded into a 3d representation. The same analogy is used in describing the 3d universe we see as a representation of the holographic information encoded on the 2d "surface" of the universe.




  1. What is meant by "information content"? Or have I stated this incorrectly?




  2. The analogy leads one to wonder if there is a way to recreate the objects that have entered a black hole in any sense. Is the information frozen on the event horizon of a black hole detectable or visible in any real sense from the outside? How is one to imagine this effect intuitively?





I understand that in thinking about the holographic analogy I may have been going completely astray so please don't snipe at the question, simply correct me.

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
