How to Avoid the Rule of the Universe
To understand how you can keep adding mass and a black hole conforming the heart of it would require like a theory of quantum gravity That we just don't even have yet. A superconductivity works this way electrons are fermions, right? They can't be in the same state But if you get two electrons together and you sort of tie them up together into a single quantum object they become a boson. There are two spin when half states combine to a spin one state and so call they couper pair And it's the key to superconductivity because now these electrons can like flow and slide in the way that bosons can In lower energy states and make things move more quickly
