Christian Outdoor Object Lesson 48: Biggest Universe



Key Text

“When I consider thy heavens… the moon and the stars, which thou hast ordained; what is man, that thou art mindful of him? and the son of man, that thou visitest him?” Psalms 8:3,4 (RV)



Lesson

Note: Todays lesson is from the book Nature Quest published by the Review and Harrold Publishing Association, a book you should have in your library!



Scientists using radio telescopes are beginning to "unearth" discoveries that stretch human imagination to its limit—and sometimes beyond. For example, they recently discovered a string of galaxies stretching halfway across the sky. This is the largest "structure" ever found in the universe. Seven hundred million light-years long, it is 10 times larger, from end to end, than any cluster of galaxies previously found.

Furthermore, the newly discovered row of galaxies is a long way from Earth: the distance varies between 100 million and 200 million light-years from our planet. When you consider that one light-year, or the distance that light travels in a year, is about 6 trillion miles, and then multiply that figure by 700 million, you have, in miles, a 4 with 21 zeros after it. If you could travel at the speed of light—or 670 million miles per hour—you would spend 100 to 200 million years getting to the new galaxies. You could then journey for hundreds of millions of years back and forth along the string. And you could visit any of the billions of stars in each galaxy, not to mention the planets that may be circling each of those stars.

If you want an idea of how big this galaxy string looks, get your star map and go outside on a clear night. This huge celestial structure extends from Pegasus to the Big Dipper. The astronomers who discovered the string suspect that it may be much longer than it appears, perhaps stretching "all the way around the sky."

Just think, the mighty Creator of all those faraway stars loves you and me! That fact is even more difficult to understand sometimes than are the vast distances in space. Perhaps that's why so many people on this planet find it difficult to believe that Jesus is real. "But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him" (Hebrews 11:6). "Lord, I believe; help thou mine unbelief" (Mark 9:24).1



Questions

Does this lesson make you feel important or small and insignificant? Why?

If you had the choice would you give up your life to save some small planet with a few people who didn’t even like you as Jesus did?

Since Jesus saved us despite our trivial place in the universe, how should we treat others?
