The pronunciation guide uses the ARPABET phonetic system—the same system used in speech recognition and text-to-speech applications.

Vowel Examples:
AE1 = cat, bat
EH1 = bed, head
IY1 = see, me
OW1 = go, boat
UW1 = boot, do
Stress Numbers:
0 = no stress (unstressed)
1 = primary stress (loud)
2 = secondary stress (medium)
Example:
AH0 TH IY1 N AH0
= a-THEE-na (Athena)

The stressed syllable (marked with 1) is pronounced louder and clearer than others.

Quick Definition

The lengthening of light waves from an object moving away from an observer.

Detailed Definition
Redshift offers poets an image of distance made visible. Because astronomers use it to measure receding galaxies, it can suggest lovers, memories, or homelands moving beyond reach. A poem may use redshift to join private loss to cosmic expansion, making separation feel both intimate and astronomical. Its reddish color can also imply fading heat, old blood, sunset, or a signal weakened by its journey through space.
Example
Example in poetry:
“The redshifted galaxies retreat like lanterns carried farther down a road” uses cosmic expansion as an image of distance; A speaker might call an absent lover “redshifted,” suggesting that time and separation have moved them beyond easy reach; “Her voice arrived redshifted through the years” adapts the scientific effect to show memory altered by distance; A space poem can note that redshift lets astronomers read motion in light, then compare that light to a message delayed across generations
Additional Notes
Redshift helps astronomers infer that distant galaxies are receding, supporting the idea of an expanding universe.
