redshift
This term describes a specific physical phenomenon where light waves are stretched, resulting in a shift toward the lower-frequency red end of the visible spectrum. It is primarily used in astrophysics to determine the velocity and distance of celestial bodies, serving as a critical diagnostic tool for understanding the expansion of the universe.
As a noun, it functions as a technical term for the observed effect. As a verb, it describes the process of the light being altered. While it is a specialized scientific term, it carries a connotation of vastness and cosmic scale, often appearing in discussions regarding the Big Bang or black holes.
Meanings
Examples
The astronomer measured the redshift of the quasar to determine its distance.
Look at this spectrum and you can see a clear redshift in the hydrogen lines.
Cosmological redshift occurs because the universe itself is stretching.
