Why the Universe is so large

https://reasonandscience.catsboard.com/t1414-why-is-the-universe-so-large

Martin Rees: 
The tremendous timespans involved in biological evolution offer a new perspective on the question 'why is our Universe so big?' The emergence of human life here on Earth has taken 4.5 billion years. Even before our Sun and its planets could form, earlier stars must have transmuted pristine hydrogen into carbon, oxygen and the other atoms of the periodic table. This has taken about ten billion years. The size of the observable Universe is, roughly, the distance travelled by light since the Big Bang, and so the present visible Universe must be around ten billion light-years across. The galaxy pair NGC 6872 and IC 4970 indicate the vastness of the Universe. Light from the bright foreground star has taken a few centuries to reach us; the light from the galaxies has been travelling for 300 million years. The Universe must be this big - as measured by the cosmic number N - to give intelligent life time to evolve. In addition, the cosmic numbers omega and Q must have just the right values for galaxies to form at all. This is a startling conclusion. The very hugeness of our Universe, which seems at first to signify how unimportant we are in the cosmic scheme, is actually entailed by our existence! This is not to say that there couldn't have been a smaller universe, only that we could not have existed in it. The expanse of cosmic space is not an extravagant superiority; it's a consequence of the prolonged chain of events, extending back before our Solar System formed, that preceded our arrival on the scene. This may seem a regression to an ancient 'anthropocentric' perspective - something that was shattered by Copernicus's revelation that the Earth moves around the Sun rather than vice versa. But we shouldn't take Copernican modesty (some-times called the 'principle of mediocrity') too far. Creatures like us require special conditions to have evolved, so our perspective is bound to be in some sense atypical. The vastness of our universe shouldn't surprise us, even though we may still seek a deeper explanation for its distinctive features.

No universe can provide several billion years of stellar cooking time unless it is several billion light years across. If the size of the universe were reduced from 1022 to 1011 stars, that smaller but still galaxy-sized universe might seem roomy enough, but it would run through its entire cycle of expansion and recontraction in about one year. And if the matter of the universe were not as homogeneous as it is, then large portions of it would have been so dense that they would already have undergone gravitational collapse. Other portions would have been so thin that they could not have given birth to galaxies and stars. On the other hand, if it were entirely homogeneous, then the chunks of matter that make development possible could not have assembled. (See John A. Wheeler, "The Universe as Home for Man." in Owen Gingerich, editor, The Nature of Scientific Discovery.)

Question: "Why did God create such a vast universe and other planets if there is only life on earth?"
Answer: The question of whether God created life on other planets is certainly fascinating. Psalm 19:1 says that "the heavens declare the glory of God, and the firmament shows His handiwork." Everything that God has made, be it you and me, or wildlife, or angels, or stars and planets, have been created for His glory. When we see a breathtaking view of the Milky Way or peer at Saturn through a telescope, I am amazed at the wonders of God!

David wrote in Psalm 8:3, "When I consider Your heavens, the work of Your fingers, the moon and the stars, which You have ordained." When we see the vast number of stars, then read that scientists have discovered thousands upon thousands of galaxies, each containing millions of stars, we should be stand in reverent fear of a God so immense to make all that and call it the work of His fingers! Furthermore, Psalm 147:4 tells us that "He counts the number of the stars, He calls them all by name." It is impossible for mankind to know how many stars there are, not to mention the “name” of every star! "Indeed My hand has laid the foundation of the earth, And My right hand has stretched out the heavens; When I call to them, They stand up together" (Isaiah 48:13).

Space and planets were created for God's glory. Although we know the stars exist, the existence of planets outside our solar system is still somewhat hypothetical, some "discoveries" have turned out to be erroneous and many are unverified, but if there are planets beyond our solar system, then these too were created for the glory of God. A constantly expanding universe is yet another conjecture that has yet to be proven. The next star farther than the sun is over 4 light-years away and that isn't even a measurable fraction of the size of the known universe, expanding or not.

As to whether there is life on other planets, we simply do not know. So far, no evidence of life on the other planets of our solar system has been found. Considering the nearness of the end times, it is unlikely that man will progress far enough to visit other galaxies before the Lord’s return. Wherever life exists or doesn’t exist, God is still the Creator and controller of all things and all things were made for His glory.

Why Is the Universe so Vast? Are We Truly Insignificant?

http://www.probe.org/site/c.fdKEIMNsEoG/b.5502887/k.FCF/Are_We_Significant_in_This_Vast_Universe.htm
What do you feel when you look at the night sky? Awe? Insignificance? Adoration? Recently, my wife and I took three Ph.D. students from China for an overnight outing at a lake in West Texas. One of the things that impressed them most was the opportunity to view the night sky on a moonless night. Due to “light pollution,” people in most cities can only make out a few hundred stars with the naked eye. These young women had never seen the night sky as King David did when he declared, “The heavens declare the glory of God!” (Psalm 19:1, NASU). They were so taken by the stars and the Milky Way that they spent several hours lying on the dock, looking up at the night sky.

These students were not Christians, and I was glad to have an opportunity to use what we know about the stars to talk to them about the overwhelming evidence for a Creator who is intensely interested in humans. However, another host may have used the same night sky to argue that if there is a God, we must not be very significant to God. Which view is correct? In this article, we will look into the Bible and into current scientific theories to better equip us to answer this important question.

According to the Bible, the transcendent Creator of this universe made humans in His own image as the focal point of His creation. Skeptics of a biblical worldview often point to the vastness of the universe as evidence that humans cannot be the focal point of a theistic creation. The famous astronomer, author, and television personality Carl Sagan put it this way:

Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.{1}

Famous physicist Stephen Hawking wrote, “Our Solar System is certainly a prerequisite for our existence . . . . but there does not seem to be a need for all these other galaxies.”{2}

In other words, why would God create this huge universe, if He was primarily interested in His relationship with one species occupying a tiny planet?

I think this is a reasonable question. After all, based on observations from the Hubble Telescope, the current best estimate for the number of stars in the observable universe is 5 times 10 to the 22nd power; that is a 5 with 22 zeros after it. How many stars is that? Well, if you were to count one star every second, it would take you only fifteen hundred trillion years to count them. These stars are spread over billions of light years. Amazingly, all of these stars account for only about 1% of the total mass of the universe. Why did God create such a vast universe, placing us on a single small planet with no reasonable hope of ever traveling beyond our solar system? Does the size of our universe run counter to a biblical worldview?

A Biblical Perspective of Humankind and the Vast Heavens

If God is the Creator of the universe, and the Bible is revelation directly from God, then accurate observation of the universe will ultimately prove to be consistent with His revelation. By combining the general revelation of science with the special revelation of the Bible, we should be rewarded with a greater understanding of the nature of our Creator and His intentions for mankind. Let’s see if this is true in addressing the vastness of the universe.

First let’s consider what God’s special revelation for us, the Bible, has to say about the vastness of the universe. The Bible often refers to God’s creative work in “stretching out the heavens” and filling it with stars (e.g. Job 9:8, Zech 12:1). A review of Bible passages on the stars and the heavens reveals a number of reasons why a vast universe is consistent with humans being the most significant part of creation.

We need to realize that creating a vast universe is not harder for God than creating a smaller universe. God brought the universe into existence out of nothing. He had no limits on the amount of matter and energy created. Consequently, it is meaningless to say that it would be a tremendous waste for God to create so many lifeless galaxies. The concept of waste only applies when there is a limited supply. When there is an unlimited supply, you can use all you desire; there is plenty more where that came from.

Within this vast universe, God placed earth in potentially the only place in the universe capable of supporting advanced life. There are many aspects of the universe that are hidden from the casual observer, but the vastness of the heavens is not one of them. God created the earth and positioned it in an ideal place so that humans could observe the vastness of the heavens and the enormous number of stars. The Bible points out at least five purposes for humans observing this vast universe:

1. To reveal His majesty and power. Job refers to this understanding as he reflected on his sufferings stating,

Who commands the sun not to shine,
And sets a seal upon the stars;
Who alone stretches out the heavens
And tramples down the waves of the sea;
Who makes the Bear, Orion and the Pleiades,
And the chambers of the south;
Who does great things, unfathomable,
And wondrous works without number.
Were He to pass by me, I would not see Him;
Were He to move past me, I would not perceive Him.
Were He to snatch away, who could restrain Him?
Who could say to Him, “What are You doing?” (Job 9:7-12).

Later, God confronts Job with His lack of understanding the full power and majesty of His Creator:

Where were you when I laid the foundation of the earth?
Tell Me, if you have understanding, . . . .
Can you bind the chains of the Pleiades,
Or loose the cords of Orion?
Can you lead forth a constellation in its season,
And guide the Bear with her satellites?
Do you know the ordinances of the heavens,
Or fix their rule over the earth? (Job 38:4, 31-33).

As we see in this passage, God intentionally did creative, wondrous works without number so that we could glimpse His greatness.

2. To emphasize our insignificance without God. The vastness of the heavens highlights how insignificant humans are apart from God’s concern for us. The primary lesson that Job learned through his experience was that we are in no position to critique God’s actions over His creation. God’s creation is so vast that any significance we have comes solely from God’s choice to be concerned with us. Job stated it this way: “Behold, I am insignificant; what can I reply to You?” (Job 40:4)

King David was the most significant person in Israel during his reign, but when he considered the vastness of God’s creation he acknowledged our insignificance:

When I consider Your heavens, the work of Your fingers,
The moon and the stars, which You have ordained;
What is man that You take thought of him,
And the son of man that You care for him (Ps 8:3-4)?

3. As a measure of His loving kindness toward us. God uses the vastness of the heavens to help us understand the magnitude of His love for us, stating, “For as high as the heavens are above the earth, So great is His loving kindness toward those who fear Him” (Ps 103:11).

God’s love for us is greater than the billions of light years which separate us from the most distant galaxies.

4. As a picture of His faithfulness and forgiveness. In a similar way, God uses our inability to completely grasp the breadth and depth of the universe to emphasize spiritual truths. Through Jeremiah, God promised a new covenant where He will remember our sins no more. God used the vastness of the heavens to convey His promise to never cast those in the new covenant away from Him with these words,

Thus says the LORD, “If the heavens above can be measured
And the foundations of the earth searched out below,
Then I will also cast off all the offspring of Israel
For all that they have done,” declares the LORD (Jer 31:37).

Even today astronomers recognize that the universe we can observe is much smaller than the state of the universe as it exists today. Due to the finite speed of light, it is impossible to directly observe the current size of the universe or count the exact number of stars. Just as the heavens can never be measured, God will never cast us off from His presence.

5. As a reminder that our understanding is limited. Our Creator understands the universe from one end to the other and from the beginning of time to its end. As humans, we are just beginning to probe its mysteries. So, God reminds us, “For as the heavens are higher than the earth, So are My ways higher than your ways And My thoughts than your thoughts” (Isa 55:9).

It is clear that God intended us to observe and study the stars and the heavens. As a part of God’s general revelation, the magnitude of the universe speaks to His greatness. Through God’s special revelation, we see God using the vastness of His creation to teach us lessons about who we are and how we relate to Him. For a Creator who was willing to sacrifice His only Son on the cross for our redemption, it would be child’s play to create a vast universe solely for our instruction. With this understanding, the vastness of the universe becomes a testament to our importance to God rather than evidence of our insignificance.

A Scientific Perspective of Humankind and the Vast Universe

If God is the Creator of the universe and the author of the Bible, accurate observation of the universe will ultimately prove to be consistent with His revelation. By combining the general revelation of science with the special revelation of the Bible, we should be rewarded with a greater understanding of the nature of our Creator and His intentions for mankind.

In his recent book Why the Universe is the Way It Is{3}, Hugh Ross points out a number of areas where combining the latest observations of astronomy and physics with biblical theology provides us with fuller answers for some of the tough questions of life. One area he focuses on is the question we have been examining: “Does the vastness of this universe mean that we are insignificant and/or accidental?”

If we assume, as most skeptics and seekers would, that the physical laws of this universe have remained constant from the beginning of the universe until now, then the current state of scientific knowledge points to three reasons why the universe must occupy the mass and volume that it does in order for advanced carbon based life to exist on this planet.

1. The exact mass of the universe was necessary for life supporting elements to exist. Life requires heavier elements such as oxygen, carbon, and nitrogen. These elements are produced in the nuclear furnaces of stars. If there were less mass in the universe, only lighter elements such as helium would be produced. If there were more mass, only heavier elements, such as iron, would be produced. In fact, the amount of mass and dark energy in the universe must be fine tuned to less than one part in 10 to the 60th power, or one part in one trillion trillion trillion trillion trillion, to have a universe that can create a life supporting solar system and planet.

2. The exact mass of the universe was required to regulate the expansion of the universe to allow the formation of the sun and the solar system. Amazingly, it turns out that the same total mass that results in the right mix of life supporting elements also results in the right amount of gravity to dampen the expansion of matter across the surface of the space-time continuum to allow the formation of stars like the sun which are capable of supporting a planet like earth. If the universe were expanding faster, stars and solar systems would not form. If the universe were expanding slower, giant stars and black holes would dominate the universe. Once again the total matter in the universe is fine tuned to support life. And what an amazing coincidence: the number that creates the right mix of elements also creates the right expansion rate. This dual fine tuning is much less likely than achieving the financial returns guaranteed by Bernie Madoff!

3. The vast volume of the universe is required to give the earth just the right amount of light and other electromagnetic radiation to support life and not destroy it. Life not only requires a planet with the right mix of elements orbiting the right kind of sun in just the right solar system; it also requires a “just right” galactic environment. Astronomers has discovered what they call “the galactic habitable zone” for our Milky Way galaxy at a distance of about 26,000 light years from the center of the galaxy. Any planet closer to the center will experience deadly radiation levels. Any planet further away from the center would lack the mix of heavy elements necessary for advanced life. But the vast majority of this habitable zone is inside one of the uninhabitable spiral arms of the galaxy. Since stars revolve around the galactic center at a rate different than the spiral arm structure based on their distance from the center of the galaxy, most solar systems pass through deadly spiral arms over the course of time. Our solar system occupies a very special place as Hugh Ross points out: “The solar system holds a special position in the Milky Way . . . the one distance from the core where stars orbit the galaxy at the same rate as its spiral arm structure does.”{4}

Once again we are faced with a divine “coincidence”: the same fine-tuned distance required to safely place a habitable planet is also the exact distance required to keep that planet out of the deadly spiral arms.

Not only must the earth be located far from the center of the Milky Way, the Milky Way must be located far enough away from other galaxies to maintain the stability of its spiral structure. Many aspects of the Milky Way appear to be very rare or unique in the universe.

As you can see, a logical application of current scientific orthodoxy based on the Big Bang and constant natural laws overwhelmingly supports the view that the vastness of the universe does not imply that human life is unremarkable and insignificant. On the contrary, the most reasonable conclusion from the evidence is that life on this planet is the primary purpose behind the vastness of our universe. Both the Bible and the results of scientific observation agree: our vast universe is the work of a Creator who considers life on earth as very significant.

Consequently, we don’t have to convince a seeker that the world is much younger than it appears in order to answer the question, “Are we significant to our Creator?” We can say, “Whether you look to the teaching of the Bible or you look at the current prevailing models from the scientific community, the answer is definitely yes!” The important question is, “Is it possible to know more about my Creator and have a relationship with Him?” Beginning with the death and resurrection of Jesus, we can explain how to have an eternal relationship with God and why we believe the Bible is the reliable source of information about our Creator and our universe.
