Two open universes connected by a wormhole: exact solutions
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 R^{2}×T_{g} (/g>=2) (4) it has no event horizons.
