When God promised Abraham that he would have innumerable descendants, He drew a striking comparison: ‘Look now toward heaven, and tell the stars, if thou be able to number them: and He said unto him, So shall thy seed be’ (Genesis 15:5).
The total number of individual stars visible in both the northern and the southern celestial hemispheres is about 6,000. Thus, on a clear night one can see at most 3,000 stars at the same time. Is that all? With the advent of telescopes, very many previously unknown stars were discovered. Galileo (1564–1642), using his homemade telescope, saw a ten-fold increase in the number of visible stars, up to 30,000.
Today, the local Milky Way galaxy (of which our sun is a part) has been found to contain 200,000 million stars. What an astounding result! If somebody could count three stars per second, after 100 years he would have counted less than five percent of this number.
Our galaxy comprises not only an unimaginable host of stars, but the size of this bright starry band in the sky is also astounding. Its diameter is said to be 100,000 light-years.
Astronomical distances are too large to be measured in kilometers, so light-years are used instead. One light-year is the distance that a light ray travels in one year. At a speed of 300,000 kilometers (186,000 miles) per second, it amounts to 9.46 million million kilometers (5.87 million million miles).
Can we really grasp such an immense size? And this is not the only galaxy. With the naked eye we can see three more, namely the two Clouds of Magellan near the southern celestial pole, and the Andromeda galaxy in the constellation of the same name. The Andromeda galaxy is thought to be 2.25 million light-years from us.1
Its total light emission is equal to 2,500 million times that of the sun. However, at this distance stars (as opposed to galaxies) having the same luminosity (light output) as the sun can no longer be proved to exist by the use of optical telescopes. The Andromeda galaxy is the most distant object in the universe that can be seen by the naked eye, except for the occasional supernova.
Numerous other galaxies have been discovered by means of the prolonged exposure of photographic plates. The total number discovered thus far is probably in the region of several hundred thousand million, and it may even amount to a few million million.
The total number of stars in the observable universe is estimated to be 1025 (1 followed by 25 zeros). Nobody knows the actual number.
What does the Bible say about the number of stars? Jeremiah writes: ‘As the host of heaven cannot be numbered, neither the sand of the sea measured: so will I multiply the seed of David my servant’ (Jeremiah 33:22). At that time, when men of learning were convinced that there were only about 3,000 stars, Jeremiah wrote that nobody would be able to count the stars. Let us consider an imaginary dialogue between Jeremiah (J) and a well known astronomer (A) of that day, about 600 years before Christ:
A: Jeremiah, you write about the number of stars as if you knew what you were saying. My colleagues and I have studied astronomy for a long time and daily concern ourselves with the stars. Our researches have made astronomy the most advanced science. Even kings appreciate and respect our findings.
J: You may have discovered many things, but you are mistaken about the number of stars.
A: How do you know that? You have not studied astronomy, not even for a single semester. So do not speak about matters which you do not understand!
J: Yes, of course my studies were in a totally different field. But I still maintain that nobody is able to count the stars, because they total such a large number, similar to the number of grains of sand on the beach.
A: We have recently completed a survey of the number of stars in the sky, employing our younger colleagues whose vision is sharp and unimpaired. They did not miss any stars, and their count was 3,000. Revise your biblical text; it has been disproved by our scientific findings.
J: I still maintain that I have written the truth. I am no expert, but I know Him Who created the stars. He has told me and I believe Him.
It is noteworthy that only now in the 20th century can we fully appreciate the astronomical import of such biblical affirmations. It behooves us to trust biblical pronouncements in other cases as well.
Let us now try to visualize the above-mentioned number of stars (i.e. 1025). No human being lives long enough to count such a large number, so we will use a computer, one of the fastest ones available. It can do 10,000 million calculations in one second, which is extremely fast! Even at this great speed it would require 30 million years of non-stop counting to count the stars, but no computer could last as long as that. God has foretold the result of such an endeavour through His prophet Jeremiah; the stars are, to all intents and purposes, countless, says the Bible, just like the sand grains on the seashore.
Isaiah tells us that God’s thoughts and ways are far higher than ours (Isaiah 55:8–9). Not only are His thoughts higher than ours, they are also much faster. He can count the stars! And He has done exactly that; He even gave each one a name: ‘He telleth the number of the stars; he calleth them all by their names ’ (Psalm 147:4). The very next verse emphasizes His greatness: ‘Great is our Lord, and of great power: his understanding is infinite.’
And yet He is also concerned about each and every human being. This is clearly expressed in Psalm 8:3–6:
‘When I consider thy heavens, the work of thy fingers, 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? For thou hast made him a little lower than the angels, and hast crowned him with glory and honour. Thou madest him to have dominion over the works of thy hands; thou hast put all things under his feet:’
In contrast, other worldviews paint a dreary and dismal picture. F.M. Wuketits, for example writes:2
‘The universe is as deaf to our lamentations as to our exuberant expressions of joy. Nobody out there in the infinite reaches of the cosmos will be sad when a certain species [referring to humans] concludes its process of self-extermination. I am sorry, but this is the only conclusion I could publish about the evolution of thought.’
Similarly bleak and false is 18th century German philosopher Immanuel Kant’s conclusion that the immeasurably large universe destroys our importance. If he had believed some of the verses of Psalm 8, he would have reached quite a different conclusion about our significance in this vast universe.
We are not cosmic outcasts, as the 19th century atheistic philosopher Nietzsche claimed, neither are we ‘gypsies at the edge of the universe’ as the 20th century French atheist biologist Jacques Monod maintained.3 On the contrary, we are beloved by our Father in heaven, through Jesus Christ, if we have accepted His salvation by grace through faith.
Heinz Kaminski, who was for many years director of the Bochum observatory, was once asked what his thoughts were when he first pointed his telescope at the heavens. He replied in part:4
‘Astronomers have reduced man to an atomic nothing; he was continuously dragged out and left to stand alone like a worm at 17,000 million light-years. He is overwhelmed by the enormous stars and vast distances. To himself he appears tiny and insignificant. Clever people have forgotten that this puny human being occupies an important place in the eye of the Creator, as can be read in the Bible. When God had created the earth … he then created man and gave him some crumbs of the greatness of his own Spirit. And these crumbs enable us to grasp something of the logistics of the entire system. If we did not carry this creative spark, we would not have been able to analyze the laws of the universe nor understand their effects.’
The universe in its immensity was especially created for us humans so that we could see and appreciate the glory and the power of God. He is so great that it required no more effort to create ten stars than one, or one thousand, or even 1025. He did not exert Himself, neither did He perspire. His creative words were sufficient: ‘For He spake, and it was done; He commanded, and it stood fast’ (Psalm 33:9).
