The Hubble tension has been a significant focus of discussion within the field of galaxy evolution and cosmology. Our approach aims to address this issue from a perspective encompassing higher redshifts, seeking to enhance our statistical understanding through surveys of the distant universe. In this study, we leverage cosmological simulation data from redshifts 2 and 3 to investigate the feasibility of conducting galaxy surveys with upcoming generation instruments. Our analyses enable us to tightly constrain parameters such as Omega_m and H_0, reaching precision levels of approximately 2% and 3%, respectively. These findings underscore the potential and significance of conducting galaxy surveys at high redshifts.
