  1. Question

    How is a wormhole formed?

    Wormholes connect blackholes. Black holes are the final stage of a star's development. In extraordinary times, such as the start of the Universe, wormholes can be created. If the changing nature of space and time is considered, it's better to think that wormholes appear and disappear. By giving wormholes careful thought, it's possible to understand that a world different from the one we live in exists.
