英文摘要	The primordial universe might be highly inhomogeneous. We perform the (3 + 1)D numerical relativity simulation for the evolution of scalar field in an initial inhomogeneous expanding universe, and investigate how it populates the landscape with both de Sitter (dS) and anti-de Sitter (AdS) vacua. The simulation results show that eventually either the field in different region separates into different vacua, so that the expanding dS or AdS bubbles (the bubble wall is expanding but the spacetime inside AdS bubbles is contracting) come into being with clear boundaries, or overall region is dS expanding with a few smaller AdS bubbles (which collapsed into black holes) or inhomogeneously collapsing.
