Topics similar to or like special relativity

Scientific theory regarding the relationship between space and time. Wikipedia

  • Spacetime

    Any mathematical model which fuses the three dimensions of space and the one dimension of time into a single four-dimensional manifold. Spacetime diagrams can be used to visualize relativistic effects, such as why different observers perceive differently where and when events occur. Wikipedia

  • Derivations of the Lorentz transformations

    There are many ways to derive the Lorentz transformations utilizing a variety of physical principles, ranging from Maxwell's equations to Einstein's postulates of special relativity, and mathematical tools, spanning from elementary algebra and hyperbolic functions, to linear algebra and group theory. This article provides a few of the easier ones to follow in the context of special relativity, for the simplest case of a Lorentz boost in standard configuration, i.e. two inertial frames moving relative to each other at constant (uniform) relative velocity less than the speed of light, and using Cartesian coordinates so that the x and x′ axes are collinear. Wikipedia

  • Twin paradox

    Thought experiment in special relativity involving identical twins, one of whom makes a journey into space in a high-speed rocket and returns home to find that the twin who remained on Earth has aged more. Incorrect and naive application of time dilation and the principle of relativity, each should paradoxically find the other to have aged less. Wikipedia

  • General relativity

    Geometric theory of gravitation published by Albert Einstein in 1915 and is the current description of gravitation in modern physics. General relativity generalizes special relativity and refines Newton's law of universal gravitation, providing a unified description of gravity as a geometric property of space and time or four-dimensional spacetime. Wikipedia

  • Spacetime diagram

    Graphical illustration of the properties of space and time in the special theory of relativity. Spacetime diagrams allow a qualitative understanding of the corresponding phenomena like time dilation and length contraction without mathematical equations. Wikipedia

  • Expansion of the universe

    Increase in distance between any two given gravitationally unbound parts of the observable universe with time. Intrinsic expansion whereby the scale of space itself changes. Wikipedia
