Possible Accidental Discovery

I may have accidentally discovered a way to locate information on the surface of a black hole. I began with a theoretical double slit experiment using a light horizon theory I made, located here:

Here is the double slit experiment:

I then asked what should happen with a double slit experiment onto the surface of a black hole:

I think the horizon of the electron(red) may have to be halved, but with a holographic universe, I find the enormous freedom of putting the experiment in the whole universe.
