I was sitting at my bed when I suddenly have an idea. The unification of electromagnetism and gravity was made with General Relativity. For this to happen, one just need to write the energy due to electromagnetic field in "differential geometry" form, through the Electromagnetic tensor, in a way that it matches with the right hand side of the Einstein equation. Then I wonder, for quantum-mechanics one just need to write the "quantized" energy of a particle in a manner to combine it with the stress-energy tensor and... uu-uhhh, we could FINALLY know what happens to particles in the singularity of a black hole. Why would it not work? I'm sorry for my bad poor English.
