Abstract Wormholes are exotic solutions of Einstein field equations of General Theory of Relativity. They are tunnel-like space-time structures connecting different universes or separated regions of one universe provided the wormhole throat remains open. The exotic matter for such traversable wormholes is required. Recent science-fiction movie “Interstellar” was made with the active participation of one of the authors of the seminal scientific paper which triggered recent wormhole research. Aspects of physics and science-fiction of wormholes are discussed.
