The universe sits on a knife’s edge. Which explanation fits that best: chance, necessity, or purpose?
Published 2026-10-11
The Sun shines. Earth moves around it. Stars form, rain falls, and matter behaves in ways that allow life. We grow up surrounded by this order and rarely question it.
But some basic features of our universe matter enormously to whether stars, planets, and life can exist. Change them enough, and the conditions for familiar life could disappear. Why does our universe allow us to be here at all?
Three answers are often offered: chance, necessity, or purpose. Islam adds a closely related thought that deserves attention. The Creator did not simply make the universe long ago and leave it running. He holds it in existence now.
Why do the universe's conditions matter so much?
Think about the Sun. Its warmth makes life on Earth possible. Yet the Sun depends on gravity, the properties of matter, and reactions inside it. The same basic rules affect other stars.
Gravity gathers matter into stars and planets. The forces inside atoms make chemistry possible. The way the universe expands affects galaxy formation. These are connected parts of one physical world.
When scientists change certain values in their models, the results can be very different. Some imagined universes might have no long-lasting stars. Others might struggle to produce the atoms needed for the chemistry we know. This is what people mean by the fine-tuning of the universe.
It does not mean scientists have proved that a designer adjusted every number. Nor does it mean the universe would instantly vanish if one number changed. The narrower point is that the conditions needed for familiar life depend on the way the universe is built.
First possibility: was it all chance?
Perhaps the universe is simply one lucky outcome. Imagine shuffling a deck of cards. The exact order you get is unlikely, but some order must appear. Perhaps the universe is like that: its conditions just happened to turn out this way.
There is something reasonable about this answer. Not every surprising result needs a plan behind it. But the card example also reveals a problem. With cards, we know the possible results. With the universe, we do not know whether its basic values were chosen randomly or how likely other values were.
That is why claims such as “the odds of our universe are one in an impossible number” should be treated carefully. Science has identified conditions that matter for life. It has not given us an agreed set of odds for the universe as a whole.
Some scientists consider another possibility: perhaps many universes exist, with different conditions. If so, it would not be strange for living beings to find themselves in one of the places where life is possible. We could not observe a place where observers never arose.
This idea, called the multiverse, is worth taking seriously. But other universes with different physical conditions have not been directly established by observation. And even if they exist, we could still ask why there is a reality capable of producing them.
Second possibility: did the universe have to be this way?
Maybe there was no cosmic lottery. Perhaps the laws of nature could never have been different, and what looks like fine-tuning is simply how reality must work.
This is the idea of necessity. A future discovery might show why some physical values have to be exactly what they are. That would be a major discovery.
For now, no confirmed theory shows that every condition needed for life had to be exactly as we find it.
There is also a deeper question. Even if the laws could not be different, why does a world governed by those laws exist? Describing how something must behave is not necessarily the same as explaining why it exists at all. This connects with the question of whether something can come from nothing.
Third possibility: what if the universe has a purpose?
The third answer is that the life-permitting order of the universe is not an accident. It exists because a Creator intended it.
No telescope has spotted God, and unanswered science questions are not evidence by themselves. This is a way of understanding the whole: an ordered universe capable of life may exist because it was intended.
Purpose cannot be measured in a laboratory, and fine-tuning alone does not prove a religion. A skeptic can reasonably ask for other evidence. That is why the wider question, does God exist?, deserves its own careful investigation.
Still, purpose has an important strength: it takes seriously not only the conditions that allow life, but the question of why there is an ordered world at all.
The Quran goes further: who is holding the universe up right now?
Here Islam gives a more specific answer. Allah did not make the universe and walk away. He continually sustains what He has made.
In Surah Fatir, Quran 35:41 says, in The Clear Quran translation by Dr. Mustafa Khattab (used throughout this article):
“Indeed, Allah ˹alone˺ keeps the heavens and the earth from falling apart.”
The verse goes on to say that if they did fall apart, no one besides Him could hold them up. The verse speaks about the universe continuing to exist, not only about its beginning.
Another passage, Quran 30:25, states:
“And one of His signs is that the heavens and the earth persist by His command.”
The word “persist” matters. The heavens and the earth are not independent things that can carry on without their Creator.
In Quran 2:255, Allah is called “the Ever-Living, All-Sustaining.” The same verse says that “the preservation of both does not tire Him.” He never tires or needs help sustaining creation.
This is what it means, in Islamic belief, to say that the universe is in its Creator's hands. It is not a picture of a human hand physically gripping the stars. Allah is not like His creation. It means that everything depends completely on His power and will. If He did not sustain it, it could not continue on its own.
But don't gravity and the laws of physics keep everything working?
Yes. Gravity explains planetary motion; physics explains stars and atoms. Belief in a Creator need not deny any of that.
Think of a phone playing music. You can explain how its speaker produces sound without answering who made the phone or why it exists. Those are different questions. In the same way, explaining how the universe works does not automatically settle whether it exists independently of a Creator.
Of course, a critic may say that nature needs no explanation beyond itself. That is a genuine philosophical disagreement, not a question that can be settled by pointing at an equation. But discovering another law of physics would not, by itself, show that the universe is independent of Allah. From the Islamic view, those laws describe the regular ways His creation operates.
The Quran also says in Quran 22:65: “He keeps the sky from falling down on the earth except by His permission.” This is a statement about divine care and control, not a replacement for astronomy.
What about all the empty, dangerous space?
A fair objection is that most of space would kill us. We cannot breathe on the Moon, and much of the universe is empty and cold. If it has a purpose, why is so little of it comfortable for us?
Fine-tuning does not mean every corner of space is made for our comfort. It means certain basic conditions make life possible somewhere. We do not know every purpose the wider universe may have.
The Quran does not ask us to believe that the universe revolves around our convenience. It invites us to think about creation. Quran 3:190 says there are “signs for people of reason” in the heavens, the earth, and the changing of day and night. In the next verse, those who reflect say: “Our Lord! You have not created ˹all of˺ this without purpose.”
That is a statement of faith about meaning. It is not a claim that human beings have already discovered every reason Allah created the universe.
So which explanation fits best?
Chance says the conditions for life may simply have happened. Necessity says perhaps they could not have been otherwise. Purpose says the universe exists because it was intended. Each faces questions and deserves a fair hearing.
The Islamic answer is purpose, but it goes beyond the idea of a one-time design. Allah gives creation its existence and sustains it at every moment. The stars do not need Him only at their beginning. Neither does Earth. Neither do we. This is a claim about why created things continue to exist, not a gap waiting for a better telescope.
That is why the knife's-edge image points toward a bigger question than whether the universe got lucky. Even if scientists eventually explain why every physical value has the value it does, we can still ask why the entire system exists and remains in being. The Quran's answer is that it does so by Allah's command. For anyone considering what the Creator is like, this is a place to begin: not with a distant maker, but with the One on whom everything depends.
