Inflaton

9/3/2026

The inflaton field is a hypothetical scalar field that is conjectured to have driven cosmic inflation in the very early universe. The field, originally postulated by Alan Guth, provides a mechanism that can generate a period of rapid expansion from 10−35 to 10−34 seconds after the initial expansion, which consequently forms a universe consistent with observed spatial isotropy and homogeneity.
