  2. Spacetime diagram - Wikipedia

    en.wikipedia.org/wiki/Spacetime_diagram

    In Minkowski's 1908 paper there were three diagrams, first to illustrate the Lorentz transformation, then the partition of the plane by the light-cone, and finally illustration of worldlines. [8] The first diagram used a branch of the unit hyperbola t 2 − x 2 = 1 {\textstyle t^{2}-x^{2}=1} to show the locus of a unit of proper time depending ...

  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. Causal structure - Wikipedia

    en.wikipedia.org/wiki/Causal_structure

    A curve in is the image of a path or, more properly, an equivalence class of path-images related by re-parametrisation, i.e. homeomorphisms or diffeomorphisms of . When M {\displaystyle M} is time-orientable, the curve is oriented if the parameter change is required to be monotonic .

    Rindler chart, for = in equation , plotted on a Minkowski diagram. The dashed lines are the Rindler horizons The dashed lines are the Rindler horizons The worldline of a body in hyperbolic motion having constant proper acceleration α {\displaystyle \alpha } in the X {\displaystyle X} -direction as a function of proper time τ {\displaystyle ...

  6. 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.

  7. 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 x = ± c 2 / α {\displaystyle x=\pm c^{2}/\alpha } and η = α τ / c {\displaystyle \eta =\alpha \tau /c} (with c = 1 , α = 1 {\displaystyle c=1,\alpha =1} ) in equation ( 2 ).

    Minkowski's theorem and the uniqueness of this specification by direction and perimeter have a common generalization: whenever two three-dimensional convex polyhedra have the property that their facets have the same directions and no facet of one polyhedron can be translated into a proper subset of the facet with the same direction of the other ...
