      Nice. He answered most of my questions except one. How big does some object need to be to cause harm to Earth as it gets consumed by the black hole moon? Also, I guess we also need to talk about spin and how the accretion disk and quasar radiation beam are oriented to say if it's pointed at Earth or not.
