• dark energy
• alternative model
• type Ia supernova

The recent observations of type la supernovae strongly support that the Universe is accelerating now and decelerated in the recent past. This may be the evidence of the breakdown of the standard Friedmann equation. Instead of a linear function of the matter density, we consider a general function of the matter density to modify the Freidmann equation. We propose a new model which explains the recent acceleration and the past deceleration. Furthermore, the new model also gives a decelerated universe in the future. The new model gives Omega(m)0 = 0.46 and z(T) = 0.44.
