  2. Quantum mechanics of time travel - Wikipedia

    en.wikipedia.org/wiki/Quantum_mechanics_of_time...

    The theoretical study of time travel generally follows the laws of general relativity. Quantum mechanics requires physicists to solve equations describing how probabilities behave along closed timelike curves (CTCs), which are theoretical loops in spacetime that might make it possible to travel through time.

  5. Time travel in fiction - Wikipedia

    en.wikipedia.org/wiki/Time_travel_in_fiction

    Time travel in modern fiction is sometimes achieved by space and time warps, stemming from the scientific theory of general relativity. [9] Stories from antiquity often featured time travel into the future through a time slip brought on by traveling or sleeping, in other cases, time travel into the past through supernatural means, for example brought on by angels or spirits.

  6. Time travel - Wikipedia

    en.wikipedia.org/wiki/Time_travel

    Time travel is the hypothetical activity of traveling into the past or future. 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 ...

    Works related to space travel have popularized such concepts as time dilation, space stations, and space colonization. [1]: 69–80 [5]: 743 While generally associated with science fiction, space travel has also occasionally featured in fantasy, sometimes involving magic or supernatural entities such as angels. [a] [5]: 742–743

    According to Kaku, technological advances that we take for granted today were declared impossible 150 years ago. William Thomson Kelvin (1824–1907), a mathematical physicist and creator of the Kelvin scale said publicly that “heavier than air” flying machines were impossible: “He thought X-rays were a hoax, and that radio had no future.” [4] Likewise, Ernest Rutherford (1871–1937 ...

    Black holes have also been portrayed as ways to travel through space. [5] [7] [12] [13] In particular, they often serve as a means to achieve faster-than-light travel. [3] [5] [7] [13] The proposed mechanism involves travelling through the singularity at the center of a black hole and emerging at some other, perhaps very distant, place in the ...
