Two Open Universes Connected by a Wormhole: Exact Solutions
Li-Xin Li
Abstract
In this paper I present a spacetime of two open universes connected by a Lorentzian wormhole. The spacetime has the following features: (1) It can exactly solve the Einstein equations; (2) The weak energy condition is satisfied everywhere; (3) It has a topology of R2× Tg (g 2); (4) It has no event horizons.
