  2. Spacetime diagram - Wikipedia

    en.wikipedia.org/wiki/Spacetime_diagram

    The term Minkowski diagram refers to a specific form of spacetime diagram frequently used in special relativity. A Minkowski diagram is a two-dimensional graphical depiction of a portion of Minkowski space , usually where space has been curtailed to a single dimension.

  3. Minkowski space - Wikipedia

    en.wikipedia.org/wiki/Minkowski_space

    Hermann Minkowski (1864–1909) found that the theory of special relativity could be best understood as a four-dimensional space, since known as the Minkowski spacetime.. In physics, Minkowski space (or Minkowski spacetime) (/ m ɪ ŋ ˈ k ɔː f s k i,-ˈ k ɒ f-/ [1]) is the main mathematical description of spacetime in the absence of gravitation.

  4. Hyperbolic motion (relativity) - Wikipedia

    en.wikipedia.org/wiki/Hyperbolic_motion_(relativity)

    Hyperbolic motion can be visualized on a Minkowski diagram, where the motion of the accelerating particle is along the -axis.Each hyperbola is defined by = / and = / (with =, =) in equation ().

  5. Relativity of simultaneity - Wikipedia

    en.wikipedia.org/wiki/Relativity_of_simultaneity

    In 1908, Hermann Minkowski introduced the concept of a world line of a particle [12] in his model of the cosmos called Minkowski space. In Minkowski's view, the naïve notion of velocity is replaced with rapidity , and the ordinary sense of simultaneity becomes dependent on hyperbolic orthogonality of spatial directions to the worldline ...

  6. World line - Wikipedia

    en.wikipedia.org/wiki/World_line

    For easy visualizations of four dimensions, two space coordinates are often suppressed. An event is then represented by a point in a Minkowski diagram, which is a plane usually plotted with the time coordinate, say , vertically, and the space coordinate, say , horizontally. As expressed by F.R. Harvey

  7. Twin paradox - Wikipedia

    en.wikipedia.org/wiki/Twin_paradox

    The vertical black line is the Earth's path through spacetime and the other two sides of the triangle show the ship's path through spacetime (as in the Minkowski diagram above). As far as the sender is concerned, he transmits these at equal intervals (say, once an hour) according to his own clock; but according to the clock of the twin ...

    Donald Trump Jr. landed in Greenland on Tuesday, just weeks after his father, US President-elect Donald Trump, ruffled feathers by reiterating his desire to obtain control over the autonomous ...

  9. Light cone - Wikipedia

    en.wikipedia.org/wiki/Light_cone

    Commonly a Minkowski diagram is used to illustrate this property of Lorentz transformations. Elsewhere, an integral part of light cones is the region of spacetime outside the light cone at a given event (a point in spacetime). Events that are elsewhere from each other are mutually unobservable, and cannot be causally connected.
