According to general relativity, objects in a gravitational field behave similarly to objects within an accelerating enclosure. For example, an observer will see a ball fall the same way in a rocket (left) as it does on Earth (right), provided that the acceleration of the rocket is equal to 9.8 m/s2 (the acceleration due to gravity on the surface of the Earth).

In this schematic diagram, time passes from left to right, with the universe represented by a disk-shaped "slice" at any given time. Time and size are not to scale. To make the early stages visible, the time to the afterglow stage (really the first 0.003%) is stretched and the subsequent expansion (really by 1,100 times to the present) is largely suppressed.

An old diagram showing the location of the Local Group, including the Solar System, within the Virgo Supercluster, revealing its location at the supercluster's outskirts with the Virgo Cluster forming its heart.[2] The Fornax Cluster shown at the left was later revealed to be a separated part of the Southern Supercluster. Both superclusters are part of the greater Laniakea Supercluster cocoon (see below).
