Concept information
Preferred term
Accelerating universe
Definition
- The deduction based on the observation that the most distant Type Ia supernovae are fainter than that expected from their redshifts in a matter-only dominated expanding Universe. The faintness is attributed to larger distances resulting from an accelerating Universe driven by presence of a new component with strongly negative pressure. This component that makes the Universe accelerate is named dark energy. (en)
