  • Absolute time and space
    Absolute space and time is a concept in physics and philosophy about the properties of the universe.
  • List of black holes
    This is a list of black holes (and stars considered probable candidates) organized by size (including black holes of undetermined mass); some items in this list are galaxies or star clusters that are believed to be organized around a black hole.
  • Relativistic mechanics
    In physics, relativistic mechanics refers to mechanics compatible with special relativity (SR) and general relativity (GR).
  • Frame of reference
    In physics, a frame of reference (or reference frame) consists of an abstract coordinate system and the set of physical reference points that uniquely fix (locate and orient) the coordinate system and standardize measurements.
  • Inertial frame of reference
    In classical physics and special relativity, an inertial frame of reference (also inertial reference frame or inertial frame, Galilean reference frame or inertial space) is a frame of reference that describes time and space homogeneously, isotropically, and in a time-independent manner.
  • Principle of relativity
    In physics, the principle of relativity is the requirement that the equations describing the laws of physics have the same form in all admissible frames of reference.
  • Spacetime
    In physics, spacetime is any mathematical model that combines space and time into a single interwoven continuum.
  • Wormhole
    A wormhole or "Einstein-Rosen Bridge" is a hypothetical topological feature that would fundamentally be a shortcut connecting two separate points in spacetime.
  • Four-current
    In special and general relativity, the four-current (technically the four-current density) is the four-dimensional analogue of the electric current density, which is used in the geometric context of four-dimensional spacetime, rather than three-dimensional space and time separately.
  • Electromagnetic tensor
    In electromagnetism, the electromagnetic tensor or electromagnetic field tensor (sometimes called the field strength tensor, Faraday tensor or Maxwell bivector) is a mathematical object that describes the electromagnetic field in space-time of a physical system.
  • World line
    The world line (or worldline) of an object is the path of that object in 4-dimensional spacetime, tracing the history of its location in space at each instant in time.
  • Sagnac effect
    The Sagnac effect (also called Sagnac interference), named after French physicist Georges Sagnac, is a phenomenon encountered in interferometry that is elicited by rotation.
  • Criticism of the theory of relativity
    Criticism of the theory of relativity of Albert Einstein was mainly expressed in the early years after its publication in the early twentieth century, on scientific, pseudoscientific, philosophical, or ideological bases.
  • Innermost stable circular orbit
    The Innermost stable circular orbit (often called the ISCO) is the smallest orbit in which a test particle can stably orbit a massive object in general relativity.
  • Wigner rotation
    In theoretical physics, the composition of two non-collinear Lorentz boosts results in a Lorentz transformation that is not a pure boost but is the composition of a boost and a rotation.
