One of my favorite things to do is to look up at the stars on a clear night.[1] For me, and many people throughout history, the stars are a confirmation of the existence of God. However, there is a trend among the non-Christian community that says that the vastness of the universe proves that God does not exist. The very fact that the universe is so big makes it unlikely that God made it. Why would God create something so big? What would be the purpose of all those stars and galaxies? Even Christians with a strong faith will sometimes ask, “Why did God create the universe so big?”

Before I answer this question let me go over exactly how big the universe is. The planets in our solar system revolve around the sun (which is a star). There are maybe 400 billion stars just in our galaxy, the Milky Way, and there are possibly billions of galaxies each with billions of stars (maybe more).

To help us understand the size of the universe let’s take a look at how long it would take for us to travel across it. The maximum speed possible according to Einstein’s theory of special relativity is 186,000 miles per second. That’s fast! “Taking off, you could circle the earth seven times in one second. Leaving our planet, you would pass the moon in two seconds and Mars in just four minutes, and it would take you only five hours to reach Pluto.”[2]

Once we leave our solar system, the next closest star is Proxima Centauri, which is 4.2 light years away. Traveling at 186,000 miles per second you would reach this star in 4.2 years. To reach the edge of the Milky Way, it would take you about 100,000 years. However, it would take you, after leaving the Milky Way, another 2.3 million years to reach Andromeda, the next closest galaxy.[3]

It would take 20 million years to reach the next galaxy after Andromeda. And all of this is only a very, very small fraction of what is out there. Remember there are billions of galaxies. If you were to do nothing but count the stars you would not live long enough to finish.[4]

NML Cygni, one of the largest known stars in the universe, with VY Canis Majoris, another large star. The little dot in the top left-hand corner is our sun. NML Cygni is about 1,650 times the radius of our sun.

So, why did God create all this, especially when most humans throughout history never knew they existed? First, I would like to turn the question around for the atheists. What if the universe was very small? Of course, an atheist would answer with something like “if God is so great and powerful, then why didn’t he create the universe bigger?” If God creates the universe small, atheists would complain; if God creates it big, well, they still complain. They are simply looking for something to argue about.

However, the original question (why God would create the universe so big) is still a great one. Let me start with Psalm 19:1 which says, “The heavens declare the glory of God; the skies proclaim the work of his hands.” The very size of the universe should make us stand in wonder and awe of God. The universe shows us just how creative and powerful God is. In fact, to God, the universe is probably rather small. Author Gary Bates says:

“Logically, the universe is not big to God. After all he’s the one who made it. Size is only relative to us as inhabitants of this universe. And size and time are related somewhat. Because the universe is big to us we consider how long it would take us to travel across it, for example. But God is ‘outside’ of the dimensions that he created (the universe), thus he is not bound by it.”[5]

This should make us even more worshipful of the Creator. And it doesn’t stop there. The vastness of the universe also shows us how important the earth is in God’s sight. Stars are technically just giant balls of gas. The simplest life form on this planet is more complex than the biggest stars. DNA has the structural complexity that makes the stars look like nothing. Plus we must remember that it doesn’t take God any more energy to create billions of galaxies than it does to create an ant. Isaiah 40:28 says, “Do you not know? Have you not heard? The Lord is the everlasting God, the Creator of the ends of the earth. He will not grow tired or weary, and his understanding no one can fathom.”

God’s love becomes clear when we think of how small we are. We are tiny dots on a tiny speck in a gigantic universe that is so large it boggles our minds. However, to God, size and distance are nothing compared to the value of a human soul.[6]

Other Thoughts

A couple of other topics are connected to the size of the universe. The first is the belief that since the universe is so big then God surely created other life out there. I do not agree with this as I have written here and here.The second has to do with Heaven. I have written elsewhere that after the second coming of Christ, he will restore the world to an Eden-like paradise (the new heavens and new earth). Since we will live in a physical world in a physical body forever then the question arises if we will be able to travel throughout the universe. Maybe, but Scripture does not answer this. It is possible.
