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.
Careful tracking of atmospheric features revealed the Great Red Spot's counterclockwise circulation as far back as 1966, observations dramatically confirmed by the first time-lapse movies from the Voyager fly-bys. [30] The spot is confined by a modest eastward jet stream to its south and a very strong westward one to its north. [31]
The universe contains pulsars, black holes, and brown dwarfs, barely lit up by white dwarfs. Over time, gravity ejects most cosmic remnants into the freezing interstellar space. Notably, neutron stars may collide and make superluminous supernovae. Extraterrestrial life might live around aging white dwarfs, which someday die and become black dwarfs.
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 ...
Gravitational time dilation is a form of time dilation, an actual difference of elapsed time between two events, as measured by observers situated at varying distances from a gravitating mass. The lower the gravitational potential (the closer the clock is to the source of gravitation), the slower time passes, speeding up as the gravitational ...
Webb's First Deep Field is the first full false-color image from the JWST, [12] and the highest-resolution infrared view of the universe yet captured. [11] The image reveals thousands of galaxies in a tiny sliver of the universe, with Webb's sharp near-infrared view bringing out faint structures in extremely distant galaxies, offering the most ...
Today it is known that an infinite universe uniformly filled with gravitating matter, if it originated in a static configuration, would indeed collapse. This conclusion originally arose from the general theory of relativity , [ 3 ] but it is also predicted by Newtonian gravity with the use of mathematical tools that were not available to Newton.
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]
