abstract: 'The most general solution of the Einstein field equations coupled with a massless scalar field is known as Wyman’s solution. This solution is also present in the Brans-Dicke theory and, due to its importance, it has been studied in detail by many authors. However, this solutions has not been studied from the perspective of a possible wormhole. In this paper, we perform a detailed analysis of this issue. It turns out that there is a wormhole. Although we prove that the so-called throat cannot be traversed by human beings, it can be traversed by particles and bodies that can last long enough.'

Introduction
============

Wormholes are one of the most intriguing objects that are allowed by the Einstein field equations. Theoretically, if they exist, they could perhaps be used as a shortcut to the furthest distances of our universe, connect our universe to another one or even be used to time travel [@PhysRevLett.61.1446; @PhysRevD.41.1116; @Lorentzianwormholes]. There is no empirical evidence to support them yet and they have always been associated with exotic matter (matter that violates the energy conditions). Nevertheless,
