Claims that wormholes exist but are too slow to be used for space travel
by
Daniel Jafferis, a physicist at Harvard University, gave a presentation at the April Meeting 2019 of the American Physical Society held in Colorado on April 13, 2019, about ' wormholes, ' which can travel in an instant between two points that would normally take tens of thousands of years. Jafferis claimed that 'wormholes exist,' but that they are not practical enough to be used for intergalactic travel as depicted in science fiction.

The wormhole theory has a long history, with the German mathematician and physicist Hermann Weyl proposing the concept in 1928. In 1957, American physicist John Wheeler coined the term 'wormhole' along with a diagram of a tube connecting two spaces. Although the existence of wormholes has not been proven, there is a theory that ' white holes ,' the existence of which is proposed based on Einstein's general theory of relativity , are connected to black holes by wormholes.

Wormholes, which literally allow travel through time and space over distances that would normally take tens of thousands of years, often appear in the world of fiction. For example, in the movie ' Contact ,' the protagonist travels through a wormhole using a device created based on a message from an alien, and arrives at Vega , about 25 light years from Earth. Also, in the anime ' Shin Getter Robo: The Last Day of the World ,' a scene is depicted in which a wormhole connecting Earth to Jupiter is somehow opened by irradiating a getter beam onto a getter tomahawk thrown at high speed.
Jafferis' research is not aimed at space travel, but at the theory of quantum mechanics. He points out that two black holes connected at the quantum level could act as a wormhole through which light can pass. This possibility means that we could use the black hole to extract light and information from far away.

'From the outside, passing through a wormhole is equivalent to quantum teleportation using entangled black holes,' Jafferis said. However, since what Jafferis is proposing is a wormhole through which light passes, 'it would take us longer to go through a wormhole than if we went directly to the site, so it's not very useful for space travel.'
'The real significance of this research is related to the black hole information problem and the relationship between gravity and quantum mechanics,' Jafferis said, explaining that studying how to construct wormholes could contribute to the development of quantum gravity theory.
