Matter and energy are both made from curved space, the flow of space creates gravitation, and the increase of space causes the expansion of the universe. Matter curves in two different directions of one dimension creates two types of electric charges: positive and negative. Matter curves in three different dimensions creates three values or charges of quark's color: red, green, and blue. The equivalent equation of space: S=Ec²=mc⁴. The gravitation of hollow sphere space: S_μν=4πGm=(4/3)π((r+a)³-r³).
