What Was There Before Space and Time? Exploring the Ultimate Mystery of the Universe

The Failure of Human Thinking: Why the Question Is Wrong
Our brain is an amazing organ that nature has designed through evolutionary processes to easily understand a world of medium-sized objects and changes at a reasonable speed. In our everyday world, every event has a cause, and every period has a "before". But when this straightforward thinking is applied to the entire universe, this logic breaks down. Nothing exists within the space and time of the universe. The Universe Is Space-Time. So the question "What was before time and space?" is fundamentally wrong—as one might ask: "What is north of the North Pole?" Stephen Hawking famously suggested that the question of what existed before the Big Bang began is meaningless. The film reel (time) began to run immediately after the projector was turned on. There is no external world where time passed during the creation of the universe. Although it has a basic instinct, our need for a "first cause" may be completely at odds with the physics of cosmic origins. The first and most important obstacle to understanding existence is this realization.
A Free Lunch in the Quantum Universe?

If there is no straightforward "something" or conventional "nothing," then the universe can sustain itself. According to contemporary Quantum Cosmology, the universe formed itself using the strange but measured logic of quantum mechanics, operating as a "zero sum universe" that requires no external input. The quantum wind is not empty on the smallest scale. In this flickering sea of quantum fluctuations, particles and antiparticles appear and disappear spontaneously, briefly gaining energy before annihilating each other. Scientists wonder why an entire universe can’t just pop into existence? On the other hand, the total energy of the universe is thought to be exactly zero. This is because the negative energy of the gravitational field perfectly balances out all the positive energy found in matter and radiation. The universe could be created for free if the positive and negative energies canceled each other out. According to this scenario, the "nothing" that existed before the Big Bang was actually a quantum field filled with potential rather than complete emptiness. We must also consider the conditions at the very start, which relate to The Singularity. This concept is vital for Quantum Cosmology.
Infinite Structure: Our Universe as a Bubble
The mystery has been pushed back a notch from zero: Where did the quantum field begin? It gives rise to notions of a vast, eternal universe where the initial explosion was merely a local event. Eternal Inflation Theory has been the most widely discussed topic. According to this theory, space beyond what we can see is rapidly and continuously expanding. In this infinite, expanding “superspace,” new regions stop expanding and burst into local Big Bangs, creating unique “bubble universes.” Our universe is just such a bubble, emerging from a transition problem within a larger, eternal structure. The Big Bang before may have been a “bounce” from an earlier cosmic contraction (a Big Crunch), according to other models such as a cyclical or oscillatory universe. This aligns with Eternal Inflation Theory.
The Holographic Principle and the Emergence of Space
The search for a “first” has led physicists to question the true nature of “space.” Is space an illusion that appears on our scale, or is it a fundamental container? Based on the study of black holes, the Holographic Principle suggests that a two-dimensional surface can encode all the three-dimensional information contained in the volume of space. Our three-dimensional universe could be a projection of data stored on a lower dimensional boundary. According to this theory, space is an emergent phenomenon rather than a fundamental entity. Based on this, some theories suggest that the strange relationship between quantum particles, called Quantum Entanglement, is the source of space itself. The geometry and fabric of entangled space are produced by the highly ordered entanglement of fundamental quantum fields. Thus, it is possible that this quantum information was "crystallized" in space at the time of the Big Bang. This emergence is closely tied to the mechanism behind the Higgs Boson Role in mass. The Holographic Principle is a complex idea.
The Ultimate Abstraction: The Mathematical Universe

The most fundamental and abstract idea is that reality is fundamentally mathematical, rather than physical. According to the Mathematical Hypothesis, mathematical structures are reality, rather than mere descriptions of it. Because their existence would be illogical, mathematical truths are necessary truths that always hold. It exists because it is necessary; no cause is necessary for its existence. This is often linked to the anthropic principle. We find ourselves in this particular universe if all conceivable, logically consistent mathematical structures actually exist (the mathematical Multiverse theory). This idea challenges our concept of The Universe Is Space-Time.
Conclusion: The Enduring Mystery of the Beginning
The enduring mystery of what was before time and space remains unsolved and dangerously blur the line between philosophy and physics. We are using tools (logic and mathematics) designed for the present universe to investigate systems where those tools do not work. The definitive answers—whether time began with the Big Bang, if the universe is a continuous fluctuation, or if our reality is a mathematically desirable structure—have yet to be established. However, important discoveries regarding the structure of reality have resulted from human efforts to address this question. The search continues, in the hope that future discoveries—possibly through the detection of primordial gravitational waves—will yield the experimental information needed to shed light on The Ultimate Mystery of existence. Until then, we must accept that the solution may be stranger, more complex, and more contradictory than our intellect can fathom. The failure of the universe to fulfill our desires was the most important lesson. This mystery is tied to Quantum Entanglement.
