Physicist Daniel Jafferis from Harvard University has theoretically confirmed the existence of traversable wormholes, or wormholes, connecting two distant points in the universe. However, travel through them should take longer than in normal space. This was announced in a press release on Phys.org.
Jafferis showed that a traversable wormhole arises between entangled black holes at a quantum level, and flying through wormholes is similar to quantum teleportation, but takes longer than the movement of a light beam from one object to another "directly". In addition, in theory, this is a special case of extracting information from a black hole.
According to one of the solutions to the equations of Einstein's general theory of relativity, wormholes can form in black holes connecting different points of the space-time continuum. However, it is believed that for the emergence of a passable wormhole, that is, such a tunnel in which a spaceship developing at light speed can move, exotic matter is needed, which creates a gravitational repulsion.
