: For much of its history, the universe's expansion was slowing down due to gravity. Scientific research, such as that detailed in the article Snapping Supernovae at

, explores how measurements of supernovae at this specific redshift help scientists pinpoint exactly when dark energy began to dominate over matter, causing the expansion to speed up. : Redshifts between (centered around

) indicates how much the light from a distant object has been stretched by the expansion of space. At approximately , several major cosmic transitions occur:

: There are several lenses for Nikon's Z-mount system with an aperture, such as the NIKKOR Z DX 24mm or the Viltrox 15mm

In consumer technology, the term may appear in the context of camera optics:
