As the universe age, the distance to the cosmic horizon increases, and previously hidden galaxies beyond the horizon should become visible.
Due to the expansion of the universe though, the distance between the galaxies increases. This has the effect that a galaxy that we can see today, would be past our cosmic horizon in the future.
Right now in the cosmic history, do the number of galaxies in the visible universe increase or decrease with time (not counting new galaxies formed within the visible universe)?
