| He and his informants converse largely in Swahili, and their cosmological references reach even beyond the boundaries of Tanzania and Mozambique. |
| Quintessence is dynamic, unlike the cosmological constant, and its average energy density and pressure slowly decay with time. |
| In the 1930s, the universe had been shown to be expanding, so the cosmological constant seemed to be erroneous. |
| We are making fast progress on understanding the implications of the existence of a cosmological constant for quantum gravity. |
| You could read that in a cosmological way, as a belief that the universe is cyclical and is going to recur. |
| No spatial stretching occurs, yet many of the observational tests of a cosmological model are verified. |
