Do Black Holes Have Cores?

Do Black Holes Have Cores?

To make a deep prediction about black holes and quantum gravity we first need to play with paper strips!

Take a strip of paper, join the ends, so you have a band. Let's use this as a model for a spin 0 particle.

Now give the paper strip 1 half twist before joining the ends. This is our model for a spin 1/2 particle.

But things get strange..

Now give the paper strip 4 half twists before joining the ends. This is a spin 2 particle. The only one known is the hypothetical graviton, carrier of the gravitational force. But if you play around with this thing for a while it will suddenly flip itself into a double thickness band with 1 half twist!

Could this imply that a graviton (spin 2) can transform into a spin 1/2 particle? Assuming charge is conserved this spin 1/2 particle must be neutral and that means a neutrino or some as yet unknown neutral particle. So a Graviton can oscillate into a spin 1/2 neutral particle.

This is just a simple model, but if graviton oscillation exists the implications are deep. Graviton oscillation would change physics as we know it. Here's 2 dramatic predictions..

1. Black holes contain a neutral spin 1/2 core
You could imagine that graviton oscillation requires extremely high graviton pressure - meaning it only occurs in super intense gravitational fields - such as in a black hole. This means the center of a black hole could be core consisting of neutral spin 1/2 particles. You can think of this core as a "graviton condensate".

2. The Law of Conservation of Angular Momentum is violated
A graviton oscillating into a spin 1/2 particle is a Boson to Fermion transition. Most physicists will hate this because it means the law of conservation of angular momentum is violated. But such a violation may be a way to detect graviton oscillation.
