It’s like this. A man has a very thick steel vault. He clams there is a pile of treasure inside. But no one can open the door to the vault. People show up with all sorts of fancy instruments, and they make indirect measurements. They then issue very authoritative-sounding statements about what is inside the vault.
But no one can get in there. This is a magic vault, you see. You can’t drill into it. You can’t blow it up. But in its vicinity, all sorts of hustlers are gathered. And they PONTIFICATE. They BLOVIATE. They wave their credentials. Reporters interview them. Governments follow their recommendations.
