Did the laws of physics come first?
· Open question
Open questionNobody knows the answer.
The open question of whether the laws of physics existed before, or apart from, the universe they describe, or arose along with it.
See it on the Science map →How it works
Every physics account of creation starts from laws: quantum rules, gravity, fields. So which came first? Platonists say laws are timeless truths, like mathematics, that the universe obeys. Theists say laws express God's mind. Followers of philosopher David Hume say laws are only summaries of what actually happens, so they cannot precede anything. Others, including John Wheeler and later Lee Smolin, suggest laws themselves emerged or evolve. Each answer changes what 'a universe from nothing' would mean.
Why it matters
It decides whether physics could ever fully explain existence. If laws must come first, the deepest question just moves back a step, from the universe to its laws.
Think of it like
Like asking whether a zoning code can exist before any city does. It might be written in advance, or it might only describe how the city actually grew.
How we know
No experiment can settle it; it is philosophy. Physics does find the laws stable: studies of distant quasar light mostly show the strength of electromagnetism unchanged, to about a part in a million, over billions of years.
Still a mystery
Why these laws and not others? Could they have been different? What, if anything, makes a law 'govern' events rather than merely describe them?

▸Why is there something rather than nothing? leads to the question Did the laws of physics come first?Open question
The relationship
Any scientific answer explains existence by laws: quantum rules, gravity, conservation. That shifts the puzzle rather than ending it. Why do those laws exist, why these ones, and in what sense do they 'exist' before anything they govern? The question of something rather than nothing becomes the question of why there is law rather than lawlessness.
How the link was found
Leibniz also asked why this world exists rather than another possible one. Einstein, as recalled by his assistant Ernst Straus, wondered whether God had any choice in creating the world.
Is it proven?
This is a logical point, not a finding: every explanation starts from something it does not explain. Philosophers and physicists broadly agree on that; they disagree on whether laws need explaining.
Open questions and mysteries
Could a single law be self-explaining, the only consistent possibility? Or is some brute fact unavoidable at the bottom of every explanation?
▸"In the beginning was the Word": creation by God's word says yes, by God's word, to Did the laws of physics come first?Faith & belief
The relationship
In this view, order comes before matter. God's word, the logos (reason, order), sets the rules, and the world follows them. Early modern scientists took 'laws of nature' literally: René Descartes derived his laws of motion from God's unchanging nature in 1644, and Newton saw the solar system's order as the work of an intelligent Lawgiver.
How the link was found
The idea of a world ordered by divine reason runs from Philo of Alexandria (1st century) and John's Gospel through Kepler, Descartes (Principles of Philosophy, 1644) and Newton's General Scholium (1713).
Is it proven?
A belief, not a testable claim. Many historians hold that it motivated early scientists to look for exact, universal laws; whether it is true lies outside science.
Open questions and mysteries
Does grounding laws in God explain them, or relocate the question? Are laws good because God decrees them, or decreed because they are good?
▸Did the laws of physics come first? gets "math is reality" from The mathematical universe hypothesisPhilosophy
The relationship
Tegmark's answer removes the gap between laws and world. If the universe is a mathematical structure, laws do not come first and then get 'obeyed'; the structure simply is the universe. Since every consistent structure would exist too, 'why these laws?' becomes 'which structure are we in?', answered by where observers like us can exist.
How the link was found
Max Tegmark, in papers of 1998 and 2007 and the 2014 book 'Our Mathematical Universe', presented it as dissolving the question of what turns equations into a real world.
Is it proven?
Philosophy. No experiment can tell a universe that is mathematics from one merely described by mathematics. Critics note it gives no rule for which structures count as real.
Open questions and mysteries
If all mathematical structures exist, why do we see such simple laws? How can anyone assign odds among infinitely many structures?
▸Did the laws of physics come first? deepens Why does math describe reality?Open question
The relationship
If laws are real and precede the universe, math's success is no accident: the world is built to an exact plan. If laws are only compact summaries of patterns, as the Humean view holds, math fits because we choose descriptions that fit. So asking which came first turns Wigner's puzzle into a question about what laws are.
How the link was found
Eugene Wigner posed the puzzle in 1960. The debate over whether laws govern or merely describe was sharpened by David Lewis (from 1973) and David Armstrong's 'What Is a Law of Nature?' (1983).
Is it proven?
Unproven either way. Both views fit all the data, since they differ only on what the data mean. Choosing between them is philosophy of science.
Open questions and mysteries
Would a 'governing' law need something to enforce it? Can a mere description explain why the future keeps obeying it?
▸Did the laws of physics come first? is the catch in A universe tunneling from nothingOpen question
The relationship
Tunneling from nothing removes space, time and matter, but keeps quantum mechanics, gravity and a field with energy. Those rules must already be 'there' for the tunneling to happen. So the theory explains the universe's appearance only given its laws. Vilenkin himself raised this, asking whether laws can exist independently of any universe.
How the link was found
Vilenkin acknowledged it in his book 'Many Worlds in One' (2006); it became the central objection in debates over Krauss's 2012 book.
Is it proven?
This is logic, not measurement: every version of the calculation starts from equations it does not derive. Supporters accept the point but argue laws are not 'things' needing creation.
Open questions and mysteries
Where, or in what sense, were the laws before the universe? Could the laws themselves have arisen with it, as Hawking later suggested?
▸Stephen Hawking asked what "breathes fire into the equations" in Did the laws of physics come first?Philosophy
The relationship
Hawking saw that even a final theory would be just equations. In 1988 he asked what breathes fire into them and makes a universe for them to describe. In 2010 he and Mlodinow answered boldly: because a law like gravity exists, the universe can create itself from nothing. Critics replied that this simply assumes the law.
How the link was found
'A Brief History of Time' (1988), final chapter; 'The Grand Design' with Leonard Mlodinow (2010). Thomas Hertog's 2023 book 'On the Origin of Time' says Hawking finally held that laws emerge with the universe.
Is it proven?
No experiment addresses it; it is philosophy. Hertog presents their last joint papers (2018) as steps toward a theory in which laws are not fixed in advance. That remains untested.
Open questions and mysteries
If laws emerged with the universe, what governed their emergence? Hawking's 1988 question still lacks a settled answer.
▸John Wheeler proposed "law without law" for Did the laws of physics come first?Speculative
The relationship
Wheeler doubted that laws were fixed before the universe. He suggested they might emerge from underlying randomness, the way steady gas laws emerge from chaotic molecules, and might be reshuffled whenever a universe collapses and is reborn. He later added that observers, by asking questions of nature, take part in making reality. Law itself would need no law.
How the link was found
Wheeler floated changeable laws in 'Gravitation' (1973, with Charles Misner and Kip Thorne) and titled a 1983 essay 'Law without Law', in a book on quantum measurement he edited with Wojciech Zurek.
Is it proven?
Speculation with no mechanism or test yet. It inspired Lee Smolin's black-hole universes, whose constants change at each rebirth, and later evolving-law proposals.
Open questions and mysteries
If laws come from randomness, what sets the rules of that randomness? Can laws change without a deeper law governing the change?
