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 ...
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 ...
A star is a massive luminous spheroid astronomical object made of plasma that is held together by its own gravity.Stars exhibit great diversity in their properties (such as mass, volume, velocity, stage in stellar evolution, and distance from Earth) and some of the outliers are so disproportionate in comparison with the general population that they are considered extreme.
The 16.5-second delay for the highest-energy gamma ray observed in this burst is consistent with some theories of quantum gravity, which state that all forms of light may not travel through space at the same speed. Very-high-energy gamma rays may be slowed down as they propagate through the quantum turbulence of space-time. [6] [7]
GRB 211106A, one of the most energetic sGRB ever registered, in the first-ever time-lapse movie of a GRB in millimeter-wavelength light, as seen by the Atacama Large Millimeter/ submillimeter Array (ALMA) [64] [65] [66] Events with a duration of less than about two seconds are classified as short gamma-ray bursts (sGRB).

These were the most remote objects discovered at the time. The pair of galaxies were found lensed by galaxy cluster CL1358+62 (z = 0.33). This was the first time since 1964 that something other than a quasar held the record for being the most distant object in the universe.

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.
