The more we learn about the universe, the more we understand—at least in a small part—what Moses knew. The universe is so large, mysterious, and glorious that it is incomprehensible to the human mind. “Worlds without number have I created,” God said to Moses. The wonders of the night sky are a beautiful testimony of that truth.
There are few things that have filled me with such breathless awe as flying in the black of night across oceans and continents and looking out my cockpit window upon the infinite glory of millions of stars.
Astronomers have attempted to count the number of stars in the universe. One group of scientists estimates that the number of stars within range of our telescopes is 10 times greater than all the grains of sand on the world’s beaches and deserts.
This conclusion has a striking similarity to the declaration of the ancient prophet Enoch: “Were it possible that man could number the particles of the earth, yea, millions of earths like this, it would not be a beginning to the number of thy creations.” — Dieter F. Uchtdorf, “You Matter to Him,” General Conference, October 2011
Through multiple revelations and translations, for example, came a description of a universe far, far exceeding the astrophysics of the 1830s, a cosmos containing “worlds without number” and advising us further that the “inhabitants thereof are begotten sons and daughters [of] God” (Moses 1:33; D&C 76:24).
Anciently, the vastness of Abraham’s eventual posterity was compared to the sand of the sea, a staggering promise (see Gen. 22:17). The Restoration’s revelations and translations accommodate a vast universe; thus it is no surprise to us that scientists’ latest estimate of the number of stars in the universe is approximately 70 sextillion—“more stars in the sky,” scientists say, “than there are grains of sand in every beach and desert on Earth” (Allison M. Heinrichs, “The Stellar Census: 70 Sextillion,”Los Angeles Times, 26 July 2003; see also Carl Sagan, Cosmos , 196). –- Neal A. Maxwell “How Choice a Seer,” General Conference, October 2003
