Engineering optical space with metamaterials could be useful to reproduce an accurate laboratory model of the physical multiverse. " This ‘metamaterial landscape’ may include regions in which one or two spatial dimensions are compactified. " Metamaterial models appear to be useful for non-trivial models such as 3D de Sitter space with one compactified dimension, 2D de Sitter space with two compactified dimensions, 4D de Sitter dS4, and anti-de Sitter AdS4 spaces.
