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.
Vesta (radius 262.7 ± 0.1 km), the second-largest asteroid, appears to have a differentiated interior and therefore likely was once a dwarf planet, but it is no longer very round today. [74] Pallas (radius 255.5 ± 2 km ), the third-largest asteroid, appears never to have completed differentiation and likewise has an irregular shape.
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 most powerful telescope to be launched into space has made history by detecting a record number of new stars in a distant galaxy. NASA's James Webb Space Telescope, history's largest and most ...

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 ...
[249] [250] LIGO-VIRGO and Fermi constrain the difference between the speed of gravity and the speed of light in vacuum to 10 −15. [251] This marks the first time electromagnetic and gravitational waves are detected from a single source, [252] [253] and give direct evidence that some (short) gamma-ray bursts are due to colliding neutron stars ...
General relativity also predicts novel effects of gravity, such as gravitational waves, gravitational lensing and an effect of gravity on time known as gravitational time dilation. Many of these predictions have been confirmed by experiment or observation, most recently gravitational waves.
