In this paper, I discuss the capabilities and limitations of an 8-10 meter ultraviolet/optical telescope in space, the proposed successor to the Hubble Space Telescope, in the context of galaxy studies. The exquisite spatial resolution and excellent sensitivity of such a facility would open up new possibilities for the study of nearby dwarf galaxies (z \la 0.5), and for studying the internal structure and kinematics of more luminous galaxies at high redshift (z \ga 2). These applications are of particular importance because they would address areas in which the popular Cold Dark Matter theory is in potential conflict with observations.
