The fact that we live in a universe so massive that light traveling at 186,000 miles per second can take
billions of years to reach us. The
Sloan Great Wall, a massive supercluster of galaxies is 1.36 billion light years long, so huge that it's length across is greater than the billion light years that separate us from it. Light from galaxies in the
The Hubble Deep Field took nearly 13 billion years to reach us, so long that none of the stars that emitted the light exist any longer. And that the farthest we've sent an object (Voyager 1) has been flying for over 35 years and is now just on the cusp of leaving our own solar system
.002 light years away
All of our history, our science, discoveries, and accomplishments occurred on one little rock orbiting one of a million trillion stars, and we will never get to see
any of it up close.
