Is Our Universe a Massive Computation? Exploring the Concept
Written on
Chapter 1: The Universe as Computation
A key proposition presented in the previous 33 articles is the notion that our universe functions similarly to a colossal computation. Testing this hypothesis involves adjusting Newton's law of gravity to determine if the revised equations yield more accurate predictions regarding star velocities.
Moreover, research into various aspects of space and time provides indirect or circumstantial evidence supporting this theory. These aspects include:
- Error-correcting codes
- Amplituhedron
- Generative Adversarial Networks (GANs) and Deep Boltzmann machines
- Constructor Theory
- Sacred Geometry and Earth's geographical features
- Life
- Consciousness
As highlighted in Article 20, "What Happens Inside a Black Hole?", Professor Seth Lloyd posits that our universe may operate as a vast quantum computer, with its history representing an extensive and continuous quantum computation. Similarly, Vlatko Vedral, in "Decoding Reality," suggests that we condense information into laws that shape our reality, which in turn guides further information compression.
This article provides a brief overview of the forthcoming seven articles.
Section 1.1: Error-Correcting Codes
According to Wikipedia:
In telecommunications, information theory, and coding theory, forward error correction—or channel coding—serves as a method for managing errors in data transmission over unreliable or noisy channels. The primary concept is that the sender encodes messages redundantly, often through an error-correcting code.
Numerous cosmologists have concluded that an error-correcting code-like structure is embedded within the quantum fabric of space-time. For instance, in 2014, three quantum gravity researchers discovered that the holographic emergence of space-time operates analogously to a quantum error-correcting code. John Preskill, a physicist at Caltech, asserts:
"[Entanglement]... is what holds space together. To weave space-time from small components, they must be entangled appropriately, and this entanglement must follow a quantum error-correcting code."
Professor James Gates has identified an error-correcting code within his string theory model of the universe, which incorporates a concept known as supersymmetry. He developed diagrams called adinkras, akin to Feynman diagrams, which are used to illustrate calculations in quantum electrodynamics. Gates notes:
"[Adinkras] possess the attributes of ones and zeros, much like how computers utilize these digits for digital information transmission. Specifically, we found a rule for error-correcting codes within the equations of supersymmetry."
Section 1.2: The Amplituhedron
According to Quanta magazine:
Physicists have uncovered a jewel-like geometric structure known as the Amplituhedron that significantly simplifies calculations of particle interactions, challenging the conventional view that space and time are fundamental elements of reality. The interactions among particles, which represent the most basic occurrences in nature, may actually stem from geometric properties. The amplituhedron isn't constructed from space-time and probabilities; rather, these aspects emerge as byproducts of its geometry. Essentially, the foundational structure of our universe can be better understood as arising from geometry instead of being a result of a pre-existing space-time framework.
Chapter 2: Connections to Computational Theory
Section 2.1: Generative Adversarial Networks
A Deep Boltzmann machine represents a type of neural network utilized in deep learning for modeling probabilistic distributions of data. Deep learning, a machine learning approach, employs Generative Adversarial Networks (GANs) for generative modeling. GANs engage in unsupervised learning, discovering patterns within input data to generate new examples that could plausibly be drawn from the original dataset. A specific variant of Deep Boltzmann machines is a GAN.
As mentioned in Article 4, "Could There Be a Logical Explanation for Our Universe?", cosmologists have identified a potential mathematical relationship between events in Anti-de Sitter (AdS) space-time and De Sitter space-time, which is believed to characterize our universe. This relationship, referred to as the AdS/CFT correspondence—where CFT denotes Conformal Field Theory—suggests that standard AdS/CFT correspondence can be conceptualized as a deep Boltzmann machine. This finding aligns with the notion that the origin and evolution of our universe are part of a GAN that discovers new patterns, indicating that our universe is intertwined with a computational process.
Section 2.2: Constructor Theory
Constructor Theory (CT), developed by David Deutsch, one of the pioneers of quantum computing, posits that CT is a meta-level theory that describes systems based on what is achievable rather than what they can do. The actions of a system emerge as a consequence. The principles of CT govern all physical laws, and these principles do not make direct assertions regarding measurement outcomes.
Deutsch does not regard computation as a priori and does not seek necessary conditions for a physical process to instantiate it. He theorizes that objective regularities exist in nature—principles of physics—which can be articulated in terms of tasks known as "computations" and the concept of "information." A task represents the transformation of an input state of substrates into an output state, with construction tasks specifying only intrinsic attributes of substrates, not extrinsic ones.
In the context of these articles, an Efimov effect represents a "task." CT provides the framework within which an Efimov effect occurs, indicating that CT must be present within a black hole. The existence of an Efimov effect suggests that CT must also encompass principles that allow for increased complexity, thereby facilitating the evolution of principles, as CT embodies an eternal process of discovering new complexities.
In summary, CT, aimed at perpetually increasing complexity, aligns with the idea of our universe as a computation while potentially elucidating many laws of physics in our universe.
Section 2.3: Sacred Geometry
Many characteristics in our universe appear to correlate with forms found in Sacred Geometry, such as the shape of the universe and the locations of the highest points on islands. While these features do not conclusively demonstrate that our universe operates as an ongoing computation, they align with the principle of least action.
The discovery of features in our universe consistent with sacred geometry suggests that the universe may have been designed to enable our understanding of its workings. Rather than explicitly revealing how the universe operates, it provides us with the means to make essential discoveries, emphasizing the importance of collaboration in comprehending the universe.
Section 2.4: The Origins of Life
Scientists have yet to reach a consensus on the origin of life. While many believe it emerged from a singular event, the reasons for this occurrence only happening once remain contentious. Over the last decade, based on general thermodynamic principles, Professor Jeremy England has formulated a hypothesis suggesting that life was inevitable.
This perspective aligns with the discussions in these articles, positing that the second law of thermodynamics serves as one mechanism for achieving the overarching goal of increased complexity. The reality that birthed our universe may have established a set of principles that underpin the laws governing it.
Our creator universe necessitates that our universe be inhabited by entities capable of comprehending its functioning. However, once a self-aware life form emerges in the creator universe, creating a second potentially competing life form may become unnecessary concerning the establishment of a process that continuously generates greater complexity. The notion of a singular event leading to life's emergence is consistent with the idea of our universe as an ongoing computation.
Section 2.5: Consciousness
The hypothesis that our universe represents a continuous quantum computation raises intriguing questions about brain function and consciousness. While most neuroscientists attribute consciousness to the forebrain, particularly the cortex, Professor Mark Solms, using data from brain-damaged patients, has found that individuals retain some sense of personal identity even with significant cortical damage. He believes consciousness is linked to the brainstem and is associated with feelings, arguing that "what we perceive is a virtual reality constructed from the mind's own materials."
While Solms' view on the origin of consciousness diverges from the arguments presented in these articles, his explanation of brain function provides a valuable model for understanding consciousness in a universe shaped by geometry and mathematics. His assertion about perceiving a virtual reality and consciousness being primarily about feelings aligns with multiple potential origins of consciousness. In essence, actual brain research supports the idea of our universe as an ongoing quantum computation.
The central question posed by this article is:
Is the evolution of our universe compatible with the concept of a computer simulation?
