Vast Orbs:   

Dutch astronomer Christiaan Huygens may have been the first person to  truly understand both the large sizes of other planets and the great  distances to other stars. In 1690, he wrote: "How vast those Orbs must  be, and how inconsiderable this Earth, the Theatre upon which all our  mighty Designs, all our Navigations, and all our Wars are transacted, is  when compared to them. A very fit consideration, and matter of  Reflection, for those Kings and Princes who sacrifice the Lives of so  many People, or to flatter their Ambition in being Masters of some  pitiful corner of this small Spot." What do you think he meant? Explain.
