If traversable wormholes exist, they might allow time travel. [31] A proposed time-travel machine using a traversable wormhole might hypothetically work in the following way: One end of the wormhole is accelerated to some significant fraction of the speed of light, perhaps with some advanced propulsion system, and then brought back to the point ...
The key to the whole idea is wormholes—specifically, a type of wormhole called a ring wormhole. Now, wormholes are already entirely theoretical, so this discussion is going to get weird.
One of the first such bounded time travel solutions found was constructed from a traversable wormhole, based on the idea of taking one of the two "mouths" of the wormhole on a round-trip journey at relativistic speed to create a time difference between it and the other mouth (see the discussion at Wormhole#Time travel). General relativity does ...
Time travel is a concept in philosophy and fiction, particularly science fiction. In fiction, time travel is typically achieved through the use of a device known as a time machine. The idea of a time machine was popularized by H. G. Wells's 1895 novel The Time Machine. [1] It is uncertain whether time travel to the past would be physically ...
Real or not, wormholes can still give scientists crucial insight into our universe.
A wormhole is a hypothetical tunnel through space-time that would allow instantaneous intergalactic travel to the most distant galaxies even billions of light years away. Wormholes are allowed by general relativity. [10]
Ring Lasers Can Allow Time Travel, Scientist Says Qi Yang - Getty Images Ronald Mallett is still working on rotating lasers to travel back in time. His working theory is based on Albert Einstein ...
The novel features travel via wormholes between alternate universes. [59] [60] [61] Diaspora: Greg Egan: 1997: The novel features scientifically well founded depictions of wormholes. [62] [63] Timeline: Michael Crichton: 1999: In the novel traversable wormholes are used for time travel along with the theory of quantum foam. [64] [65] The Light ...
