This question is mostly about my lack of understanding of light cones, and how a light cone is manifested physically in a small, local region of space.
So I'm somewhere inside a black hole -- not spaghettified and still alive, but definitely past the event horizon.
My understanding is that all light will be moving in a direction toward the singularity (or rather that all directions are toward the singularity).
Were I facing directly away from the singularity as I fell in a straight line towards it, popular knowledge says that I would see the "outside" reduced to an ever smaller disk in front of me. Presumably some weird time stuff would happen and the light would intensify as well.
But if I fell straight in facing toward the black hole and holding an object directly in front of me (and assuming I'm not immediately destroyed by the black hole's photosphere), what would happen? Would it be redshifted until it disappears upon crossing the horizon? Can light travel back from the object toward my eyes but only on a small local scale (and long term, the light will end up in the singularity), would I ever observe the object crossing the horizon? Were I to turn around (could I turn around?) and look at the object and my arm from behind me, how distorted would it look?
