The Problem With the Cosmic Constant

I was thinking about in the case of Nukem's paradox, if you believe in quantum mechanics, then the existence of this kind of spooky being who knows exactly what the future is going to hold. I don't think that many worlds either implies eternalism or is against it or anything like that. You can be classical eternalist perfectly well or a bony eternalist or whatever. All right, I'm going to group two questions together. What would the Planck scale have to be for the number to be as small as the observed cosmological constant?
