  2. Wormhole - Wikipedia

    en.wikipedia.org/wiki/Wormhole

    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 of origin. Alternatively, another way is to take one entrance of ...

  3. Time travel - Wikipedia

    en.wikipedia.org/wiki/Time_travel

    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 ...

    “The time machine is a natural consequence of the wormhole existing,” Toby Wiseman, a professor of theoretical physics at the Imperial College London who was not a part of the study, told New ...

    en.wikipedia.org/wiki/Chronology_protection...

    This occurs when the two wormhole mouths, call them A and B, have been moved in such a way that it becomes possible for a particle or wave moving at the speed of light to enter mouth B at some time T 2 and exit through mouth A at an earlier time T 1, then travel back towards mouth B through ordinary space, and arrive at mouth B at the same time ...

  6. Tipler cylinder - Wikipedia

    en.wikipedia.org/wiki/Tipler_cylinder

    A Tipler cylinder, also called a Tipler time machine, is a hypothetical object theorized to be a potential mode of time travel—although results have shown that a Tipler cylinder could only allow time travel if its length were infinite or with the existence of negative energy.

    Among the co-authors of this 1990 paper were Kip Thorne, Mike Morris, and Ulvi Yurtsever, who in 1988 had stirred up renewed interest in the subject of time travel in general relativity with their paper "Wormholes, Time Machines, and the Weak Energy Condition", [4] which showed that a new general relativity solution known as a traversable ...
