The chicken-or-egg conundrum of whether the universe or the laws that govern it came first is a question that delves into the very heart of cosmology and the nature of existence. It is a question that challenges our understanding of time and the universe itself. The concept of first implies a linear progression of time, which may not be applicable before the Big Bang, as time is believed to have come into existence only with the birth of our universe. Furthermore, the notion of universal laws governing the universe may be more descriptive than prescriptive, as they are a means to understand and explain the universe rather than a force that dictates its behavior.

The concept of 'first' is irrelevant without time, which only exists in the universe
The concept of "first" is irrelevant without time, and time only exists in the universe. Asking which came first, the universe or universal laws, is not a well-posed question. Time is a part of the spacetime structure of the universe, not something extrinsic to it.
If there was something before the Big Bang, it would still be part of the same "universe/multiverse" and common laws must hold. The laws that govern the universe are descriptive, not prescriptive. They are a way of understanding and explaining the universe, not a separate entity that exists independently of it.
The question of what came first, the universe or its laws, assumes a linear concept of time that may not apply. The evolution of time is a way of slicing up and experiencing the universe, and it is within this context that the notion of "first" and sequence of events arises.
Furthermore, the concept of "first" implies a discrete change or switch, which is not how laws work. If there was a change or switch, it would itself follow some rules, and could be incorporated into a bigger unifying theory.
Therefore, the more fundamental question is whether it makes sense to talk about "outside the universe." If the universe is defined as everything there is, then the answer is no. This leads to the consideration of abstract concepts, such as the rules of math and logic, which transcend any reality and are true in any imaginable universe or absence thereof.

![The universe and the stars, being an original theory on the visible creation, founded on the laws of nature, by Thomas Wright. 1837 [Leather Bound]](https://m.media-amazon.com/images/I/41qaVm0pKML._AC_UY218_.jpg)
The Big Bang is the edge of the universe, and time and space must be considered together
The Big Bang is often described as an ""explosion" that marked the beginning of the universe. However, this is a misleading image as it implies that fragments were flung out from a central point into a pre-existing space. Instead, the Big Bang theory suggests that the universe originated from a singularity, an extremely dense and hot state, and has been expanding ever since. This expansion is uniform in all directions, causing distant objects to recede from us at a rate proportional to their distance.
Now, considering the question of whether the Big Bang is the edge of the universe, it's important to understand that the concept of an "edge" implies a finite boundary or limit to the universe. However, observations suggest that the universe may be infinite in size, with no observable edge or center. The universe appears to be flat, indicating that its density is very close to the critical density required for a flat universe. If the universe had significantly deviated from this critical density over time, it would have either reached a heat death or a Big Crunch, neither of which has occurred.
Furthermore, the concept of the Big Bang as the edge of the universe is intricately linked with the notion of spacetime. Time and space are not separate entities but are intertwined in the fabric of the universe. The Big Bang marks not only the beginning of the universe but also the inception of time itself. Without time, the concept of "first" does not exist. Thus, if the Big Bang is indeed the edge of the universe in spacetime, it must be considered as a whole, with time and space together.
Moreover, the Big Bang theory provides valuable insights into the early stages of the universe. Shortly after the Big Bang, the universe consisted of a "soup" of fundamental particles such as neutrons, electrons, and protons, which were too hot to allow visible light to pass through. Over time, these particles cooled and combined to form neutral atoms, setting the stage for the building blocks of everything that exists today. This evolution in time is a way of slicing up and experiencing the universe, and it gives rise to the notion of sequence and causality.
In conclusion, the Big Bang can be considered the edge of the universe in the sense that it marks the beginning of spacetime. However, it's important to understand that the universe may not have a finite edge or boundary. The concept of spacetime unifies time and space, and the Big Bang, as the starting point of spacetime, underscores the integral connection between these two dimensions. The Big Bang theory provides a framework for understanding the early universe and the subsequent evolution of its structure and composition.

The laws of math and logic transcend reality and are true in any universe
The concept of which came first, the universe or universal laws, is a philosophical question that delves into the nature of existence and the role of physical laws in governing the universe. This question challenges the very notion of "first" because time itself is a part of the universe's spacetime structure.
However, some argue that the laws of math and logic transcend reality and are true in any universe. These abstract concepts, such as the rules of math and logic, are independent of any specific universe or reality. They are seen as absolute truths that hold regardless of whether a universe exists or not. This view aligns with the philosophy of Plato, who proposed that numbers and mathematical laws exist outside of space and time, beyond the reach of humans.
The effectiveness of mathematics in describing the fundamental laws of the universe remains a mystery. Scientists and mathematicians are yet to fully understand why mathematics works so well in this regard. Some, like Einstein, have questioned the certainty of mathematical laws in relation to reality, suggesting that they may be independent of each other. Others, like Stanislas Dehaene, have explored the innate aptitude for mathematics in humans and other species, indicating a biological basis for our understanding of mathematical concepts.
While the debate continues, it is important to recognize that mathematics and logic provide a framework for understanding and predicting the universe, even if their origin and applicability transcend the boundaries of any single universe.

Parity symmetry must have been broken for the universe to create more matter than antimatter
The concept of time is integral to the universe; therefore, it is challenging to determine whether the universe or universal laws came first. According to the Big Bang theory, the universe should have equal amounts of matter and antimatter. However, we observe a significant imbalance, with baryonic matter dominating our everyday experiences. This matter-antimatter asymmetry problem remains a puzzle for physicists.
Parity symmetry, or P-symmetry, refers to the idea that the laws of physics should treat a system and its mirror image the same way. In the context of particle physics, it implies that a particle and its antiparticle should behave identically. However, to explain the dominance of matter over antimatter in the universe, we must consider violations of this parity symmetry.
One approach to understanding this violation is through the concept of CP-symmetry, which combines charge conjugation (C) with parity symmetry (P). CP-symmetry dictates that a particle and its antiparticle should exhibit the same behaviour when their electric charges are reversed. However, experiments have revealed that the laws of nature do not apply equally to matter and antimatter, indicating a violation of CP-symmetry.
Andrei Sakharov proposed three necessary conditions for baryon-generating interactions to produce matter and antimatter at different rates, known as the Sakharov conditions. These conditions include C-symmetry and CP-symmetry violation, interactions out of thermal equilibrium, and baryon number violation. By satisfying these conditions, the universe could generate an excess of baryons over anti-baryons, leading to the observed dominance of matter.
The violation of CP-symmetry has been observed in experiments with neutrinos, where matter neutrinos and antimatter neutrinos oscillate at significantly different rates. This asymmetry could provide crucial insights into the matter-dominated universe. However, it is important to note that the evidence for neutrino asymmetry is still considered weak, and further research is needed to verify these findings.

The laws of physics have changed, and new theories are needed to explain how
The concept of time only exists in the universe, and time is part of the spacetime structure of the universe. Therefore, the question of what came first, the universe or universal laws, is not well-posed. However, it is worth considering that the laws of physics have indeed changed over time, and new theories are needed to explain how.
The laws of physics are often regarded as unchangeable, with any newly discovered law acquiring a quasi-legal status, and any defined constant being assumed to remain fixed. However, this assumption has been challenged by recent findings. An international group of physicists analyzed light from distant quasars and reported a shift in the fine-structure constant over billions of years. The fine-structure constant is a measure of the inherent strength of electromagnetic interactions and is believed to have a value of approximately 1/137 since the beginning of time. However, the team's findings, published in the Physical Review Letters, contradict this belief.
The fine-structure constant is a combination of the speed of light, the charge of the electron, and Planck's constant. It determines the relative positions of the dark lines in the spectrum that result from atoms absorbing certain wavelengths of light. By studying the spacing of absorption lines from 72 distant quasars, the researchers found that the fine-structure constant was 0.001% smaller billions of years ago. This conclusion has significant implications, as it challenges fundamental assumptions in physics.
While the findings are controversial and subject to skepticism, they open up new avenues for exploration and theory-building. Scientists have also used GPS technology to find variations in constants at the heart of quantum physics, further challenging the notion of unchanging physical laws. These discoveries underscore the need for new theories that can accommodate the evolving nature of the laws of physics and provide a more nuanced understanding of the universe.
In conclusion, while the question of whether the universe or universal laws came first may not be well-posed due to the nature of time and spacetime, it is evident that the laws of physics are not static. The changing values of constants and the evolving understanding of quantum physics demand new theories that can explain these shifts and provide a more dynamic framework for understanding the universe.

Frequently asked questions
There is no clear answer to this question. Some argue that the concept of "first" doesn't apply, as time only exists within the universe. If there was something before the Big Bang, it would still be part of the same "universe/multiverse" and subject to the same laws.
Universal laws, specifically the laws of physics, play a crucial role in explaining why anything exists at all. For example, the violation of "parity symmetry" during the Big Bang resulted in more matter than antimatter, allowing the universe to form.
Yes, the laws of physics have changed over time. For instance, the laws of physics today exhibit "parity symmetry," treating left-handedness and right-handedness equally. However, in the past, parity symmetry must have been broken to explain the abundance of matter over antimatter.
The discussion of universal laws leads to philosophical questions about the nature of reality and the role of concepts like math and logic. Some argue that these abstract concepts transcend any particular reality and are true in any imaginable universe.
