Introduction \n In modern physical cosmology, the cosmological principle is the notion that the spatial \n distribution of matter in the universe is homogeneous and isotropic where homogeneous \n is defined as \"The universe is same in all locations\" while isotropic means \"The universe \n is same in all directions\". These concepts are important because most of the modern \n cosmology is based on the \"Cosmological principle\" the assumption that on large scale, \n the universe is both homogeneous and isotropic. The cosmological observations obtained \n by Type Ia Supernova Tonry et al. [17] and large scale structure Tegmark et al. [16], \n Percival et al. [13]. Sharif and Siddiya [15] have studied of Homogeneous and Isotropic \n universe in f(R, T) gravity. Katanaev [9] also investigated cosmological model with \n homogeneous and isotropic spatial sections. Shamir [14] investigated the exact vacuum \n solutions of Bianchi type I, III space times. Chandel and Ram [7] have studied spatially \n homogeneous cosmological models in f(R, T) theory of gravity. \n The distribution of matter can be satisfactorily describe by perfect fluid due to the large \n scale distribution of galaxies in our universe. Stiff fluid cosmological models create \n interest in the study because for these models, the speed of light is equal to speed of \n sound and its governing equation have the same characteristic as those of gravitational \n field. Zel'dovich [21] and Barrow [5] have discussed the relevance of stiff fluid equation","bbox":{"left":0.168111,"top":0.542278,"width":0.6662969999999999,"height":0.286876}}],"images_bbox":[],"images_bbox_not_text_overlap":[]}
