✦ Synopsis

In this paper, I present a space-time of two open universes connected by a Lorentzian wormhole. The space-time 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); ( ) it has no event horizons.
