Blackbody Distribution for Wormholes

TL;DR

This paper proposes that the quantum state of multiply-connected wormholes follows a Planckian distribution for field momenta, suggesting such wormholes are essential for the existence of an observable classical universe.

Contribution

It introduces a novel Planckian probability measure for wormholes' momenta, contrasting with classical Gaussian assumptions, and links wormhole existence to the emergence of a classical universe.

Findings

Wormhole momenta follow a Planckian distribution.

Classical universe existence depends on wormhole occurrence.

Quantum state assumptions lead to specific probability measures.

Abstract

By assuming that only (i) bilocal vertex operators which are diagonal with respect to the basis for local field operators, and (ii) the convergent elements with nonzero positive energy of the density matrix representing the quantum state of multiply-connected wormholes, contribute the path integral that describes the effects of wormholes on ordinary matter fields at low energy, it is obtained that the probability measure for multiply connected wormholes with nondegenerate energy spectrum is given in terms of a Planckian probability distribution for the momenta of a quantum field $\frac{1}{2}\alpha^ {2}$, where the $\alpha$'s are the Coleman parameters, rather than a classical gaussian distribution law, and that an observable classical universe can exist if, and only if, such multiply connected wormholes are allowed to occur.
