Revisiting the boundary conditions for a Morris-Thorne wormhole

Abstract

In physical science, the concept of \emph{emergence} is often used to describe phenomena that occur at macroscopic scales but not at microscopic scales. The latter is usually referred to as a \emph{fundamental property} and the former as an \emph{emergent property}. In this paper, noncommutative geometry, often viewed as an offshoot of string theory, is the primary fundamental theory that gives rise to macroscopic wormholes and their properties, thereby becoming an emergent phenomenon. As a consequence of these considerations, we will reexamine the boundary conditions that characterize a Morris-Thorne wormhole. The result is a significant modification of the wormhole structure.
