The flatness problem arises because only a universe with "F1F1F1S1F1F1F10_mass+ F1F1F1S1F1F1F10F1F1F1S1_F1F1F10 = 1" can have that value forever. The equation states that the density of the universe is exactly critical, which means that the universe's curvature will stay flat over time. If the universe's density were any different than this critical value, the curvature of space would change over time, and the universe would not be flat.
