In this study, quark and strange quark matter which exist in the first seconds of the early Universe have been studied in the context of general relativity to be able to obtain space-time geometry of first seconds of the early Universe. For this purpose, Einstein's field equations for quark and strange quark matter in the non static spherically symmetric space-time have been solved by using experimental result that anisotropy parameter of quark matter is very small. We have concluded from obtained solutions that the space-time structure of first seconds of the Early Universe is homogeneous and isotropic. Also we have concluded that the color interactions of the quarks may be origin of primordial magnetic field in the early universe.
