Definition of cosmological constant in English: cosmological constantnoun Physics An arbitrary constant in the field equations of general relativity. Example sentencesExamples - Quintessence is dynamic, unlike the cosmological constant, and its average energy density and pressure slowly decay with time.
- We are making fast progress on understanding the implications of the existence of a cosmological constant for quantum gravity.
- Einstein introduced the cosmological constant to his equations of general relativity because he believed the universe was static.
- On the plus side, the vanishing vacuum energy that is implied by supersymmetry ensures that the cosmological constant vanishes.
- Why is the cosmological constant, which characterizes the energy density of the vacuum, so small?
