Rethinking Reality: The Unwritten Story of Time

The universe is not a closed book, but rather a narrative in progress—its future pages unwritten, its history ever-expanding. The digits that define time, instead of being predetermined, seem to emerge in concert with our unfolding experience, hinting at a reality that is both participatory and creative.

Introduction

Time: we all experience its steady march, feel its passing in our bodies, and witness its effects as trees stretch skyward, animals age, and objects wear down. Our everyday understanding of time is one of motion—a ceaseless flow from past, to present, into an open future. Yet, what if the very nature of time is not what it seems? Physics offers a perspective that is at odds with our intuition, challenging us to rethink everything we believe about reality.

Albert Einstein’s revolutionary theory of relativity upended this familiar notion, proposing that time is not merely a backdrop to events, but a fourth dimension intricately woven into the fabric of the universe. In his “block universe” concept, the past, present, and future exist together in a four-dimensional space-time continuum, and every moment—from the birth of the cosmos to its distant future—is already etched into reality. In this cosmic tapestry, the initial conditions of the universe determine all that follows, leaving little room for the unfolding uncertainty we sense in our lives [1].

Contrasting Views: Einstein, Quantum Mechanics, and the Nature of Time

Most physicists today accept Einstein’s pre-determined view of reality, in which all events—past, present, and future—are fixed within the space-time continuum. However, some physicists who explore the concept of time more deeply find themselves troubled by the implications of this theory, particularly when the quantum mechanical perspective is considered. At the quantum scale, particles act in a probabilistic manner, existing in multiple states at once until measured; it is only through measurement that a particle assumes a single, definite state.

While each measurement of a particle is random and unpredictable, the overall results tend to conform to predictable statistical patterns. The behaviour of quantum particles is described by the evolution of their wave function over time. Quantum wave functions require a fixed spacetime, whereas relativity treats spacetime as dynamic and observer-dependent. This fundamental difference complicates efforts to develop a theory of quantum gravity capable of quantizing spacetime—a major challenge in modern physics [2].

Relativity, in contrast, insists that time and space be treated equally, making it necessary to introduce time as an operator and place it on the same level as position coordinates. In quantum mechanics, each particle is part of a system with many particles, and time and space coordinates are not treated equally. In such systems, there are as many position variables as there are particles, but only a single time variable, which represents a flaw in the theory. To overcome this, scientists have developed the many-time formalism, where a system of N particles is described by N distinct time and space variables, ensuring equal treatment of space and time [3].

If physicists are to solve the mystery of time, they must weigh not only Einstein’s space-time continuum, but the fact that the universe if fundamentally quantum, governed by probability and uncertainty. Quantum theory treats time in a very different way than Einstein’s theory. Time in quantum mechanics is rigid, not intertwined with the dimensions of space as it is in relativity.

Gisin’s Intuitionist Approach and Indeterminacy

Swiss physicist Nicolas Gisin has published papers aiming to clarify the uncertainty surrounding time in physics. Gisin argues that time—both generally and as we experience it in the present—can be expressed in intuitionist mathematics, a century-old framework that rejects numbers with infinitely many digits.

Using intuitionist mathematics to describe the evolution of physical systems reveals that time progresses only in one direction, resulting in the creation of new information. This stands in stark contrast to the deterministic approach implied by Einstein’s equations and the unpredictability inherent in quantum mechanics. If numbers are finite and limited in precision, then nature itself is imprecise and inherently unpredictable.

Gisin’s approach can be likened to weather forecasting: precise predictions are impossible because the initial conditions of every atom on Earth cannot be known with infinite accuracy. In intuitionist mathematics, the digits specifying the weather’s state and future evolution are revealed in real time as the future unfolds. Thus, reality is indeterministic and the future remains open, with time not simply unfolding as a sequence of predetermined events. Instead, the digits that define time are continuously created as time passes—a process of creative unfolding.

Gisin’s ideas attempt to establish a common indeterministic language for both classical and quantum physics. Quantum mechanics establishes that information can be shuffled or moved around, but never destroyed. However, if digits defining the state of the universe grow with time as Gisin proposes, then new information is also being created. Thus, according to Gisin information is not preserved in the universe since new information is being created by the mere process of measurement.

The Evolving Nature of Time

As we survey the landscape of contemporary physics, it becomes apparent that our classical conception of time is far from settled. Instead, it stands at the crossroads of discovery—a concept perpetually reshaped by new theories and deeper reflection. Einstein’s vision of a pre-determined reality, where all moments are frozen within the space-time continuum, offers comfort in its order and predictability. Yet, this view is challenged by the quantum world, where uncertainty reigns, and events transpire in a haze of probability until measurement brings them into sharp relief.

The friction between the determinism of relativity and the indeterminacy of quantum mechanics compels us to look beyond conventional frameworks. Quantum mechanics treats time as an inflexible backdrop, severed from the intricacies of space, whereas relativity insists on weaving time and space together, equal and dynamic. Gisin’s intuitionist approach further invites us to reflect on the very bedrock of reality—questioning whether information is static or endlessly generated as the universe unfolds.

This ongoing dialogue between classical physics and emerging quantum perspectives not only exposes the limitations of our current understanding but also sparks a profound sense of curiosity. If, as Gisin suggests, information is continuously created, then the universe is not a closed book, but rather a narrative in progress—its future pages unwritten, its history ever-expanding. The digits that define time, instead of being predetermined, seem to emerge in concert with our unfolding experience, hinting at a reality that is both participatory and creative.

Exploring Quantum Computing and Wormholes: A New Frontier

 As we continue to unlock the secrets of quantum gravity and teleportation, each discovery invites us to ponder just how much more there is to unveil, a testament to the infinite possibilities that lie hidden within the quantum tapestry of our universe. The next revelation may be just around the corner, waiting to astonish us all over again, bringing us closer to understanding our universe, and our place within it.

Introduction

Imagine voyaging across the galaxy at warp speed, like in Star Trek or Star Wars, where starships zip through cosmic shortcuts called wormholes. While these cinematic adventures may seem far-fetched, the wildest twist is that wormholes aren’t just a figment of Hollywood’s imagination—quantum physics hints they might truly exist, emerging from the very fabric of quantum entanglement. This remarkable idea flips our understanding of the universe: space and time could actually spring from invisible quantum connections, reshaping what we know about black holes and the universe itself.

This revolutionary perspective burst onto the scene in 2013, thanks to Juan Maldacena and Leonard Susskind, who suggested that whenever two systems are maximally entangled, a wormhole connects them, anchoring each system at opposite ends [1]. Building on the pioneering work of Einstein, Podolsky, and Rosen (EPR) on quantum entanglement and the Einstein-Rosen (ER) description of wormholes, Maldacena and Susskind daringly bridged quantum physics with general relativity, inviting us to think of our universe as far stranger, and far more interconnected, than we ever imagined [2].

Einstein-Rosen Bridges and the Origins of Wormholes

In their seminal paper, Einstein and Rosen encountered the concept of wormholes while seeking to describe space-time and the subatomic particles suspended within it. Their investigation centred on disruptions in the fabric of space-time, originally revealed by German physicist Karl Schwarzschild in 1916, just months after Einstein published his theory of relativity.

Schwarzschild demonstrated that mass can become so strongly self-attractive due to gravity that it concentrates infinitely, causing a sharp curvature in space-time. At these points, the variables in Einstein’s equations escalate to infinity, leading the equations themselves to break down. Such regions of concentrated mass, known as singularities, are found throughout the universe and are concealed within the centres of black holes. This hidden nature means that singularities cannot be directly described or observed, underscoring the necessity for quantum theory to be applied to gravity.

Einstein and Rosen utilized Schwarzschild’s mathematical framework to incorporate particles into general relativity. To resolve the mathematical challenges posed by singularities, they extracted these singular points from Schwarzschild’s equations and introduced new variables. These variables replaced singularities with an extra-dimensional tube, which connects to another region of space-time. They posited that these “bridges,” or wormholes, could represent particles themselves.

Interestingly, while attempting to unite particles and wormholes, Einstein and Rosen did not account for a peculiar particle phenomenon they had identified months earlier with Podolsky in the EPR paper: quantum entanglement. Quantum entanglement led quantum gravity researchers to fixate on entanglement as a way to explain the space-time hologram.

Space-Time as a Hologram

The concept of space-time holography emerged in the 1980s, when black hole theorist John Wheeler proposed that space-time, along with everything contained within it, could arise from fundamental information. Building on this idea, Dutch physicist Gerard ‘t Hooft and others speculated that the emergence of space-time might be similar to the way a hologram projects a three-dimensional image from a two-dimensional surface. This notion was further developed in 1994 by Leonard Susskind in his influential paper “The World as a Hologram,” wherein he argued that the curved space-time described by general relativity is mathematically equivalent to a quantum system defined on the boundary of that space.

A major breakthrough came a few years later when Juan Maldacena demonstrated that anti-de Sitter (AdS) space—a theoretical universe with negative energy and a hyperbolic geometry—acts as a true hologram. In this framework, objects become infinitesimally small as they move toward the boundary, and the properties of space-time and gravity inside the AdS universe precisely correspond with those of a quantum system known as conformal field theory (CFT) defined on its boundary. This discovery established a profound connection between the geometry of space-time and the information encoded in quantum systems, suggesting that the universe itself may operate as a vast holographic projection.

ER = EPR

Recent advances in theoretical and experimental physics have leveraged the SYK (Sachdev-Ye-Kitaev) model to explore the practical realization of wormholes, particularly in relation to quantum entanglement and teleportation. Building on Maldacena’s 2013 insight that suggested a deep connection between quantum entanglement (EPR pairs) and wormhole bridges (ER bridges)—summarized by the equation ER = EPR—researchers have used the SYK model to make these ideas more tangible. The SYK model, which describes a system of randomly interacting particles, provides a mathematically tractable framework that mirrors the chaotic behaviour of black holes and the properties of quantum gravity.

In 2017, Daniel Jafferis, Ping Gao, and Aaron Wall extended the ER = EPR conjecture to the realm of traversable wormholes, using the SYK model to design scenarios where negative energy can keep a wormhole open long enough for information to pass through. They demonstrated that this gravitational picture of a traversable wormhole directly corresponds to the quantum teleportation protocol, in which quantum information is transferred between two entangled systems. The SYK model enabled researchers to simulate the complex dynamics of these wormholes, making the abstract concept of quantum gravity more accessible for experimental testing.

Fig 1. How a quantum computer simulated a wormhole

By 2019, Jafferis and Gao, in collaboration with others, successfully implemented wormhole teleportation using the SYK model as a blueprint for their experiments on Google’s Sycamore quantum processor. They encoded information in a qubit and observed its transfer from one quantum system to another, effectively simulating the passage of information through a traversable wormhole as predicted by the SYK-based framework. This experiment marked a significant step forward in the study of quantum gravity, as it provided the first laboratory evidence for the dynamics of traversable wormholes, all made possible by the powerful insights offered by the SYK model.

Conclusion

Much like the mind-bending scenarios depicted in Hollywood blockbusters such as Star Trek and Star Wars, where spaceships traverse wormholes and quantum teleportation moves characters across galaxies, the real universe now seems to be catching up with fiction.

The remarkable journey from abstract mathematical conjectures to tangible laboratory experiments has revealed a universe far stranger, and more interconnected, than we could have ever imagined. The idea that information can traverse cosmic distances through the fabric of space-time, guided by the ghostly threads of quantum entanglement and the mysterious passageways of wormholes, blurs the line between science fiction and reality.

 As we continue to unlock the secrets of quantum gravity and teleportation, each discovery invites us to ponder just how much more there is to unveil, a testament to the infinite possibilities that lie hidden within the quantum tapestry of our universe. The next revelation may be just around the corner, waiting to astonish us all over again, bringing us closer to understanding our universe, and our place within it.

Beyond Barriers: How Quantum Tunneling Powers Our Digital and Cosmic World

From memory devices to the heart of stars

Consider the operation of a flash memory card, such as an SSD or USB drive, which is capable of data retention even when powered off; the immense energy output from the sun and stars; or research indicating the occurrence of enzyme catalysis and DNA mutation [1]. These diverse applications are unified by the quantum mechanical phenomenon known as quantum tunneling.

Quantum tunneling refers to the capacity of particles to penetrate energy barriers despite lacking the requisite energy to surpass these obstacles according to classical mechanics. This effect arises from superposition, which imparts wave-like characteristics to quantum-scale particles and permits probabilistic presence across multiple locations. The transmission coefficient, which quantifies the likelihood of tunneling, is determined by the barrier’s height and width, in addition to the particle’s mass and energy [2].

Application of the time-independent Schrödinger equation allows the decomposition of the particle’s wave function into components situated within and outside the barrier. By ensuring continuity of the wave functions at the boundaries, the transmission coefficient can be derived. This theoretical framework has been effectively utilized in various fields, including the development of scanning tunneling microscopes and quantum dots.

Running your digital world

Modern electronics exist in a delicate balance with quantum tunneling. At the heart of today’s microprocessors are advanced transistors, which depend on the quantum ability of electrons to traverse ultra-thin insulating barriers. This tunneling enables transistors to switch on and off at remarkable speeds while using minimal energy, supporting the drive for faster, more energy-efficient devices. As technology advances and the insulating layers within transistors are made thinner to fit more components onto a single chip, the probability of electrons tunneling through these barriers inevitably increases. This leads to unwanted leakage currents, which can generate excess heat and disrupt circuit performance. Such leakage is a major challenge, setting hard physical boundaries on how much further Moore’s law—the trend of doubling transistor density— can be extended.

Yet, the same quantum effect that poses challenges in mainstream electronics is ingeniously exploited in specialized components. Tunnel diodes, for example, are engineered with extremely thin junctions that encourage electrons to quantum tunnel from one side to the other. This property allows tunnel diodes to switch at incredibly high speeds, making them invaluable for high-frequency circuits and telecommunications technologies where rapid response times are essential.

Quantum tunneling is also fundamental to how data is stored in non-volatile memory devices such as flash drives and solid-state drives (SSDs). In these devices, information is retained by manipulating electrons onto or off a “floating gate,” separated from the rest of the circuit by a thin oxide barrier. When writing or erasing data, electrons tunnel through this barrier, and once in place, they remain trapped, even if the device is disconnected from power. This is why your photos, documents, and other files remain safely stored on a USB stick or SSD long after you unplug them.

In summary, quantum tunneling is both a challenge and a tool in modern electronics. Engineers must constantly innovate to suppress unwanted tunneling in ever-smaller transistors, while simultaneously designing components that rely on controlled tunneling for speed, efficiency, and reliable data storage. This duality underscores how quantum mechanics is not merely an abstract scientific theory, but a practical force shaping the infrastructure of everyday digital life.

Powering stars, chips, and qubits

On a cosmic scale, quantum tunneling is fundamental to the process by which stars, including the Sun, emit light. It facilitates the fusion of protons within stellar cores by enabling them to overcome their mutual electrostatic repulsion, thus allowing nuclear fusion to occur at temperatures lower than those required in a strictly classical context. The existence of life on Earth relies on this mechanism, as it powers the energy output of stars that sustain our planet. Insights into tunneling continue to inform research efforts aimed at developing fusion reactors, where analogous physical principles must be managed under controlled conditions rather than governed by stellar gravity.

In superconducting circuits, which comprise materials capable of conducting electric current without resistance, pairs of electrons known as Cooper pairs tunnel through thin insulating barriers called Josephson junctions. When cooled to near absolute zero, these systems enable billions of paired electrons to behave collectively as a single quantum entity. This phenomenon has resulted in devices with exceptional sensitivity for measuring voltage and magnetic fields. Additionally, Josephson junctions play a central role in the architecture of superconducting qubits, where precision control of tunneling between quantum states enables reliable quantum logic operations.

The Nobel Prize in Physics 2025 was awarded to John Clarke, Michael H. Devoret, and John M. Martinis for their pioneering work in designing a macroscopic system utilizing a Josephson junction. The system was composed of two superconductors separated by an ultra-thin oxide layer, only a few nanometers thick. This layer permitted electron tunneling, and the observed discrete energy levels were in complete conformity with quantum mechanical predictions, a notable accomplishment from both experimental and theoretical standpoints [3].

A feature, a bug, and a design principle

Imagine a world where the chemical foundations of life and technology remain a mystery. Without quantum mechanics, our understanding of chemical bonds would be impossibly incomplete, the very medicines that save lives daily could never be designed, and the machines and electronics we rely on in our daily lives would not be possible.

Quantum tunneling stands as a striking testament that quantum phenomena are not mere scientific oddities; they are the bedrock of modern innovation. The same quantum effect that challenges engineers by causing troublesome current leaks in ever-smaller transistors is deliberately harnessed for breakthroughs: non-volatile memory, lightning-fast diodes, atomic-resolution microscopes, and the frontier of quantum computing all depend on it.

Every second, billions of electrons tunnel invisibly within the technology that surrounds you, their quantum behaviour silently orchestrating our digital universe. Far from being an abstract theory, quantum mechanics is the invisible engine driving your phone, your computer, your lasers, and LEDs—the essential infrastructure of twenty-first century life. Our entire technological existence pivots on the strange but real phenomena of the quantum world, challenging us to see science not as distant or esoteric, but as the very substance of our everyday reality.

Quantum Revolution: How Max Planck Tapped Into the Universe’s Zero-Point Mysteries

Unveiling the Ever-Vibrant Fabric of Reality

Introduction

At the dawn of the twentieth century, Max Planck embarked on a quest to unravel how energy is absorbed and emitted by the filaments within light bulbs, aiming to maximize their efficiency and illuminate more while consuming less power. In doing so, Planck not only resolved practical engineering challenges, but also ignited a scientific revolution that fundamentally reshaped our comprehension of physics and the universe itself.

Planck’s investigations shattered the classical notion that energy flows in a seamless, continuous stream. Instead, he revealed that energy is exchanged in tiny, indivisible packets known as quanta. This radical insight gave birth to quantum theory, a new framework that challenged long-held assumptions and transformed our understanding of the physical world, from the behaviour of the smallest particles to the structure of the cosmos.

The significance of Planck’s discovery extends far beyond theoretical physics. By demonstrating that energy exchanges are quantized, he opened the door to a wave of scientific breakthroughs, paving the way for technologies such as semiconductors, lasers, and quantum computing. Moreover, subsequent research based on Planck’s work uncovered the existence of zero-point energy: even in the coldest conceivable state, where classical theory predicted absolute stillness, quantum systems retain a subtle but unceasing vibrancy. This revelation overturned the classical thermodynamic belief that all motion ceases at absolute zero, unveiling a universe in perpetual motion at its most fundamental level.

Planck’s legacy is profound, not only did he lay the foundations for quantum mechanics, but his insights continue to inspire new discoveries that help us probe the mysteries of existence. By deepening our grasp of reality’s underlying fabric, Planck’s work has transformed how we see our place in the universe, inviting us to explore how the strange and wonderful quantum world shapes everything from the nature of matter to the emergence of life itself.

The Black Body Problem and Ultraviolet Catastrophe

As the nineteenth century turned, new technologies such as the light bulb drove increased interest in the interaction between materials and radiation. Efficient engineering of light bulbs demanded a deeper understanding of how materials absorb and emit energy, especially the filaments inside the bulbs. In the early 1890s, the German Bureau of Standards commissioned Planck to optimize light bulb efficiency by identifying the temperature at which bulbs would radiate mainly in the visible spectrum while minimizing energy loss in the ultraviolet and infrared regions [1].

Prior attempts to explain the behaviour of heated materials, notably the Raleigh-Jeans law, predicted infinite energy emission at short wavelengths – the so-called ultraviolet catastrophe. These models often relied on the concept of an ideal material that perfectly absorbs all wavelengths, termed a black body. The ultraviolet catastrophe led directly to the “black body problem,” as experimental results contradicted the notion that materials like lightbulb filaments would emit infinite energy at high temperatures.

Planck addressed this issue by conducting experiments with electrically charged oscillators in cavities filled with black body radiation. He discovered that the oscillator could only change its energy in minimal increments, later quantified as h (Planck’s constant). The energy exchanged was proportional to the frequency of the electromagnetic wave and occurred in discrete quantities, or quanta. This finding gave rise to quantum theory and revealed a deeper truth: energy remains with the oscillator (or the atoms in the material) even at absolute zero temperature.

Zero-Point Energy and Its Implications

By solving the ultraviolet catastrophe through his black body absorption equation, Planck discovered zero-point energy (ZPE). Unlike the catastrophe, the existence of zero-point energy was verified experimentally, overturning classical thermodynamics’ expectation that all molecular motion would cease at absolute zero.

Zero-point energy accounts for phenomena such as vacuum-state fluctuations, where even an electromagnetic field with no photons is not truly empty but exhibits constant fluctuations due to ZPE. One of the most fascinating examples is the Gecko – a lizard capable of traversing walls and ceilings on nearly any material. The Gecko exploits quantum vacuum fluctuations present in the zero-point energy of the electromagnetic field. Its feet are covered with millions of microscopic hairs that interact with the quantum vacuum fluctuations of any nearby surface, resulting in an attractive force known as van der Waals force, a microscopic form of the Casimir effect. Through this process, the Gecko draws energy from the vacuum field, demonstrating nature’s ability to harness zero-point energy.

Experimental Advances in Harnessing Zero-Point Energy

Research teams from Purdue University and the University of Colorado Boulder have shown that energy from the vacuum state can be accessed through the Casimir force, which acts on micro-sized plates in experimental setups. Although the effect is small and produces limited energy, more efficient methods may be possible using quantum vacuum density and spin. The impact of spin is visible in fluid systems like hurricanes and tornadoes. By inducing high angular momentum vortices with plasma coupled to the quantum vacuum, researchers can create energy gradients much larger than those observed with simple non-conductive plates in the Casimir effect.

These pioneering investigations illuminate how quantum phenomena, once confined to abstract theory, are now being harnessed in the laboratory to extract measurable effects from the very fabric of space. While the practical application of zero-point energy remains in its infancy, the ongoing refinement of experimental techniques – such as manipulating spin and plasma interactions – offers glimpses of a future where the subtle energy fields underlying all matter could become a resource for technological innovation. Each advance deepens our appreciation for the intricate interplay between quantum mechanics and the observable world, suggesting that the restless energy pervading the vacuum is not merely a curiosity, but a potential wellspring of discovery and transformation that may one day reshape our understanding of both energy and existence.

Conclusion

Max Planck’s pursuit to optimize the humble light bulb did far more than revolutionize technology, it opened a window into the deepest workings of the universe. By questioning how filaments absorb and emit energy, Planck uncovered the quantum nature of reality, revealing that energy is exchanged in discrete packets, or quanta, rather than in a continuous flow. This insight not only solved the black body problem and the ultraviolet catastrophe but also led to the discovery of zero-point energy, the realization that even at absolute zero, particles never truly rest, and the universe itself is in perpetual motion. 

Zero-point energy shows us that nothing in the cosmos is permanent. Particles continuously move, shift, and even appear and disappear, embodying a universe that is dynamic and ever-changing. As humans, we are inseparable from this cosmic dance. Our bodies, thoughts, and lives are woven from the same quantum fabric, always in flux, always evolving. Planck’s work reminds us that change is not just inevitable, it is fundamental to existence itself. In understanding zero-point energy, we come to see that reality is not a static backdrop, but a vibrant, restless sea of possibility, where both matter and meaning are constantly being created and transformed.

Quantum Entanglement: ‘Spooky Action at a Distance’

The atoms that comprise all matter – including those composing our bodies – originated from distant stars and galaxies, emphasizing our intrinsic connection to the universe at fundamental scales. It is perhaps an inescapable conclusion that our reality is defined by how we observe and view our universe, and everything within it.

Introduction

In 1935, Albert Einstein, Boris Podolsky, and Nathan Rosen published a paper addressing the conceptual challenges posed by quantum entanglement [1]. These physicists argued that quantum entanglement appeared to conflict with established physical laws, and suggested that existing explanations were incomplete without the inclusion of undiscovered properties, referred to as hidden variables. This argument, later termed the EPR argument, underscored perceived gaps in quantum mechanics.

Quantum entanglement represents a significant and intriguing phenomenon within quantum mechanics. It describes a situation wherein the characteristics of one particle within an entangled pair are dependent on those of its partner, regardless of the spatial separation between them. The particles involved may be electrons or photons, with properties such as spin direction serving as examples. Fundamentally, entanglement is based on quantum superposition: particles occupy multiple potential states until observation forces the system into a definite state. This state collapse occurs instantaneously for both particles.

The implication that measuring one particle’s property immediately determines the corresponding property of the other – even across vast cosmic distances – suggests the transmission of information at speeds exceeding that of light. This notion appeared to contradict foundational principles of physics as understood by Einstein, who referred to quantum entanglement as “spooky action at a distance” and advocated for a more satisfactory theoretical explanation.

Modern understanding of entanglement

The EPR argument highlighted the conventional concept of reality as consisting of entities with physical properties that are revealed through measurement. Einstein’s theory of relativity is based on this perspective, asserting that reality must be local and that no influence can propagate faster than the speed of light [2]. The EPR analysis demonstrated that quantum mechanics does not align with these principles of local reality, suggesting that a more comprehensive theory may be required to fully describe physical phenomena.

It was not until the 1960s that advances in technology and clearer definitions of measurement permitted physicists to investigate whether hidden variables were necessary to complete quantum theory. In 1964, Irish physicist John S. Bell formulated an equation, Bell’s inequality, which holds true for hidden variable theories but not exclusively for quantum mechanics. If real-world experiments failed to satisfy Bell’s equation, hidden variables could be excluded as an explanation for quantum entanglement.

In 2022, the Nobel Prize in Physics honored Alain Aspect, John Clauser, and Anton Zeilinger for their pioneering experiments utilizing Bell’s inequality, which significantly advanced our understanding of quantum entanglement. Unlike earlier thought experiments involving pairs of electrons and positrons, their work employed entangled photons. Their findings definitively eliminated the possibility of hidden variables and confirmed that particles can exhibit correlations across vast distances, challenging pre-quantum mechanical interpretations of physics.

Furthermore, these experiments demonstrated that quantum mechanics is compatible with special relativity. The collapse of the states of two entangled particles upon measurement does not entail information transfer exceeding the speed of light; rather, it reveals a correlation between entangled particle states governed by randomness and probability, such that measuring one immediately determines the state of the other.

Conclusion

When he called it “spooky action at a distance”, Einstein sought to understand entanglement within the context of local reality. The EPR argument subsequently highlighted the non-local nature of reality through quantum entanglement. Although information cannot be transmitted faster than the speed of light, quantum entanglement demonstrates that the states of entangled particles exhibit instantaneous correlations, ensuring that any transfer of information remains consistent with causality and relativity.

Quantum entanglement underscores the indeterminate nature of reality prior to observation. Rather than existing as predetermined outcomes, reality according to quantum systems resides within vast fields of probability that are defined upon measurement. Additionally, the atoms that comprise all matter – including those composing our bodies – originated from distant stars and galaxies, emphasizing our intrinsic connection to the universe at fundamental scales. It is perhaps an inescapable conclusion that our reality is defined by how we observe and view our universe, and everything within it.
