  4. 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. Gravitational time dilation - Wikipedia

    en.wikipedia.org/wiki/Gravitational_time_dilation

    Gravitational time dilation is a form of time dilation, an actual difference of elapsed time between two events, as measured by observers situated at varying distances from a gravitating mass. The lower the gravitational potential (the closer the clock is to the source of gravitation), the slower time passes, speeding up as the gravitational ...

    [250] [251] LIGO-VIRGO and Fermi constrain the difference between the speed of gravity and the speed of light in vacuum to 10 −15. [252] This marks the first time electromagnetic and gravitational waves are detected from a single source, [253] [254] and give direct evidence that some (short) gamma-ray bursts are due to colliding neutron stars ...

  9. General relativity - Wikipedia

    en.wikipedia.org/wiki/General_relativity

    The same experimental data shows that time as measured by clocks in a gravitational field—proper time, to give the technical term—does not follow the rules of special relativity. In the language of spacetime geometry, it is not measured by the Minkowski metric. As in the Newtonian case, this is suggestive of a more general geometry.
