It is amazing. It is amazing how large a galaxy is and even more amazing how many galaxies there are.
One or two trillion in just the observable universe, which may only be a tiny fraction of the total universe. I read in one of Brian Greene’s books that if inflation theory is correct, the universe must be at least 10^20 times the radius of the visible horizon. And since volume increases with the cube of the radius, that’s how many galaxies? Answer: unimaginable.
