In this case, we are referring to the statement that space is homogeneous and isotropic. Homogeneous means the properties of space are the same everywhere, that is, space is invariant under any translation. Isotropy means the properties of space are the same in all directions, that is, space is invariant under all rotations

okay now i got it because our profeesor said that homogenous means that the center of coordinates is chosen anywhere while isotropic means the direction for any axis is invarient . thank you
