  The creation of universes in entangled pairs may avoid the initial
singularity and it would have observable consequences in a large macroscopic
universe like ours, at least in principle. In this paper we describe the
creation of an entangled pair of universes from a double instanton, which
avoids the initial singularity, in the case of a homogeneous and isotropic
universe with a conformally coupled massless scalar field. The thermodynamical
properties of inter-universal entanglement might have observable consequences
on the properties of our single universe provided that the thermodynamics of
entanglement is eventually related to the classical formulation of
thermodynamics.
