OBSERVATIONAL CONSTRAINTS ON COSMOLOGY FROM THE MODIFIED FRIEDMANN EQUATION
The Astrophysical Journal, 603: 365-370, 2004 march 10，-0001，（）：
Recent measurements of Type Ia supernovae, as well as other concordant observations, suggest that the expansion of our universe is accelerating. A dark energy component has usually been invoked as the most feasible mechanism for the acceleration. However, effects arising from possible extra dimensions can mimic dark energy through a modified Friedmann equation. In this work, we investigate some observational constraints on ascenario in which this modification is given by H2
