    The methodology used in Timelapse of the Entire Universe. In 2012, a short, one-and-a-half-minute film by Boswell, Our Story in 1 Minute, is published. It is a shorter version of Timelapse of the Entire Universe, specifically in one minute and 29 seconds, and used closed captions to evoke reflection on humanity. It also used imageries from this ...

  4. General relativity - Wikipedia

    en.wikipedia.org/wiki/General_relativity

    To understand Einstein's equations as partial differential equations, it is helpful to formulate them in a way that describes the evolution of the universe over time. This is done in "3+1" formulations, where spacetime is split into three space dimensions and one time dimension. The best-known example is the ADM formalism. [174]

  7. Imaginary time - Wikipedia

    en.wikipedia.org/wiki/Imaginary_time

    Imaginary time is a mathematical representation of time that appears in some approaches to special relativity and quantum mechanics. It finds uses in certain cosmological theories. Mathematically, imaginary time is real time which has undergone a Wick rotation so that its coordinates are multiplied by the imaginary unit i.

  8. Gravity of Earth - Wikipedia

    en.wikipedia.org/wiki/Gravity_of_Earth

    The gravity g′ at depth d is given by g′ = g(1 − d/R) where g is acceleration due to gravity on the surface of the Earth, d is depth and R is the radius of the Earth. If the density decreased linearly with increasing radius from a density ρ 0 at the center to ρ 1 at the surface, then ρ ( r ) = ρ 0 − ( ρ 0 − ρ 1 ) r / R , and the ...

    Higher-dimensional Einstein gravity is any of various physical theories that attempt to generalise to higher dimensions various results of the well established theory of standard (four-dimensional) Albert Einstein's gravitational theory, that is, general relativity.
