EXCERPT: . . . Let’s move on to some sillier questions. One time you said that the Large Hadron Collider disproves the existence of ghosts. But what if ghosts were made out of dark matter, like axions?
BC: It’s missing the point. In order to have a ghost, there must be some thing that interacts with the matter in your body. Whatever that thing is constructed out of, then it has to interact strongly with matter at the energies with which we observe the world now – room temperature. Axions wouldn’t do that at this energy. A classical ghost, or a soul, would have to interact strongly with the body.
We have a very precise understanding of how matter interacts and we see no evidence at these energies of matter interacting with the Standard Model. I’m sure there will be new interactions, but they will be very subtle and visible at the highest energies. But that doesn’t help you when it comes to your body, or a ghost floating through your bedroom.
