One of the two most prominent models of this entity has equation-of-state parameter varying in time downward from one-third; the other has equation-of- state parameter negative one.
One of the two most prominent models of this entity has equation-of-state parameter varying in time downward from one-third; the other has equation-of- state parameter negative one. One proposed experiment to measure this would examine acceleration near type (*) Ia supernovas. The flattening of potentials by this phenomenon should be observable as decreased CMS redshift at late times because the effect of this entity increases with time. The second aforementioned model corresponds to the subtraction of a constant from the left-hand side of the Friedmann equation; those models are respectively quintessence and the cosmological constant. For 10 points, identify this interaction potential that may comprise up to three-fourths of the universe, a theorized energy proposed to explain the acceleration of universal expansion.
