"In photographs the entire Universe seems to be jammed full of galaxies, with hardly a space between them (if you'll pardon the pun). But this isn't really the case, and it would be more accurate to say that the Universe is pretty much empty. And all the galaxies within it, our own included, are themselves also largely made up of nothing, so much nothing in fact that you could fly across any galaxy you care to think of, at the speed of light, with your eyes shut, without much risk of bumping into anything." (ASTRONOMY & SPACE) This article discusses the vastness of space, stressing that the universe is mostly empty in spite of the billions of galaxies that it contains.
