The recent observations of type Ia supernovae strongly support that the universe is accelerating now and decelerated in past. This may be evidence breakdown standard Friedmann equation. Instead a linear function matter density, we consider general density to modify Freidmann We propose new model which explains acceleration past deceleration. Furthermore, also gives future. $Ω_{m0}=0.46$ $z_T=0.44$.
