Hořava Lifshitz Gravity Prevents Annihilation in black holes

Hořava Lifshitz Gravity

Theoretical physicists have attempted to reconcile Albert Einstein’s General Relativity with quantum mechanics’ restless, uncertain universe. A new study suggests that Hořava-Lifshitz (HL) gravity, a modified theory of gravity, may have the potential to solve a long-standing scientific mystery: the destiny of stuff within a black hole.

Under Takamasa Kanai from Kochi College’s National Institute of Technology, the research team has proposed a new explanation of the universe’s fundamental equations’ “ultraviolet” (UV) behavior. By studying the Wheeler-DeWitt (WDW) equation, also known as the “wave function of the universe,” the researchers found that black holes may not undergo the terrifying “annihilation” many expect.

Problem with Singularities

Classical general relativity views space and time as a four-dimensional fabric. In the center of a black hole, this model collapses, creating a singularity with infinite density and zero volume where physics breaks out. Scientists have believed that a coherent quantum gravity theory would “smooth out” these singularities, but the mathematical path to such a theory has been plagued by “infinities” that are nearly impossible to compute.

What is Hořava-Lifshitz Gravity?

Kanai and colleagues utilized Hořava-Lifshitz gravity to circumvent mathematical obstacles. Unlike General Relativity, HL gravity creates a basic “anisotropy” between space and time at high energies. At the “ultraviolet” scale, the realm of extremely short distances and strong curvatures deep inside a black hole scales differently in space and time.

This paradigm is revolutionary because it allows “renormalization,” a mathematical method that tames quantum gravity infinities. By eliminating Lorentz invariance at high energies, HL gravity simplifies geometry’s quantum dynamics and achieves power-counting renormalizability.

Stopping “Annihilation-to-Nothing”

The “annihilation-to-nothing” scenario was the study’s biggest finding. Wave packets reflecting conflicting time directions or space geometries nearing a singularity in earlier quantum gravity models may cancel each other out, culminating in “nothingness.”

However, the Kochi College team showed that the terms that dominate the high-energy UV regime in HL gravity attenuate this annihilation behavior. A “minisuperspace” model, which simplifies the universe for precise mathematical answers, was used to study spherical, planar, and hyperbolic structures.

In each case, they found:

The wave function inside the black hole remains strong.

A “running scaling parameter” and high-order curvature terms stabilize quantum systems near the singularity and event horizon.

In the UV domain of HL gravity, wave packets are not annihilated.

A Quantum Bounce Instead of Singularity?

Significant implications follow this revelation. If the wave function survives, quantum processes may cause a “quantum bounce” or stable inner state. This solves the singularity problem that has puzzled physicists since Einstein by preventing black hole density from becoming infinite. Researchers conclude that the normal annihilation-to-nothing behavior of Hořava-Lifshitz gravity does not occur in the ultraviolet domain. This suggests that the previously anticipated “nothingness” is a mathematical trick of General Relativity that disappears with quantum principles.

The Future of Quantum Cosmology

The Wheeler-DeWitt equation is the most powerful window into the creation of the universe and the mysterious depths of black holes. This work is part of a global effort to understand it. Kanai’s team has developed analytical answers based on mathematical reasoning rather than computer simulations, unlike other teams like Aalto University’s.

Even the current research focuses on parameter values approaching the General Relativistic limit, future research will investigate more scenarios and more complex black hole constructs. For now, a black hole’s interior appears to be a stable quantum structure rather than a disaster zone. Observing the universe through Hořava-Lifshitz gravity reveals a more stable and intriguing universe than expected.

Is the Speed of Light Really Constant? A Cosmic Test Just Challenged Einstein

Unlock the deepest cosmic secrets as we challenge one of the most fundamental rules of physics itself–the speed of light. Researchers at the Universitat Autönoma de Barcelona combined the measurements of very high energy gamma rays coming from distant cosmic sources to test whether photons of different energies travelled at the same speed. Maybe Einstein was wrong?

Random Matrix Product States RMPS Unlock Early Cosmology

A Seoul National University-MIT physics collaboration produced a research in December 2025 that significantly changed our understanding of the early universe. Using Random Matrix Product States (RMPS), researchers Sunghoon Jung, Sungjung Kim, Jiwoo Park, and Seokhyeon Song have been able to study the universe’s “initial state” when Einstein’s General Relativity’s smooth geometry disintegrates into a turbulent “quantum foam.”

Breakthrough: Quantum Foam Mapping

This discovery centres on “gravitationally prepared states”. In quantum field theory, these states represent a closed world’s quantum wave function. They are constructed by visualising a universe where gravity has boundary limitations but matter does not. These states preserve the whole history of gravitational events, which is vital for universe evolution.

Researching these states has been difficult due to their intricacy. Standard scientific methods struggle to explain “higher topologies” or “Wormhole Phase Transition,” complex spacetime geometries with many holes and bridges. Before this study, traditional semiclassical techniques were assumed to be unable to determine the contributions of these complex structures to the universe.

Understanding Gravity-Ready States

The research team solved these problems with Random Matrix Product States. The “tensor network” apparatus was designed for many-body quantum systems, including atom behaviour in crystals. The researchers added randomness to these matrices to represent quantum gravity’s statistical behaviour.

The RMPS approach is unprecedentedly accurate. It can construct complex geometric configurations, including quantum entanglement “replica geometries,” to all orders of approximation. With this precision, scientists may study how past gravitational history affects matter fields now.

Innovation: Random Matrix Product States
Key findings include the “bra-ket wormhole phase transition” confirmation. “Bra” and “ket” are the two sides of a quantum probability computation. These two sides are connected gravitationally by a Wormhole Phase Transition.

As the universe’s geometry alters fundamentally, this phase shift may be mathematically assured, the researchers found. This is guaranteed if the RMPS “transfer matrix” fits the spectral gapping property. This conclusion is essential because it provides a rigorous mathematical basis for understanding why and when wormholes dominate early cosmic physics, moving the issue from theoretical speculation to mathematics.

Bra-Ket Wormhole Phase Transition

The “off-shell” wormhole revelations were astounding. Classical physics calls configurations that follow equations of motion “on-shell” like a tossed ball. However, “off-shell” structures are quantum fluctuations and do not follow classical paths.

Because gravity models lack stable classical solutions, they often miss off-shell wormholes, whereas the RMPS model can include them. The researchers found that off-shell structures lead to nonzero long-distance correlations in gravitationally prepared states. This shows that a wormhole’s quantum presence connects distant portions of the cosmos even if it isn’t a fixed “bridge” and may leave quantitative evidence for researchers to locate.

Long-distance correlations and off-shell wormholes
The researchers extended their model from two-dimensional to continuous space to study de Sitter gravitationally prepared states. This is relevant to our reality because de Sitter space provides the mathematical model for accelerated expansion, like cosmic inflation.

By applying matrix models to de Sitter space, the group created a new “toolkit” for studying quantum gravity events with non-perturbative effects that are too powerful or sophisticated for step-by-step approximation. This research sheds light on quantum phenomena and spatial geometry.

Cosmological Implications: de Sitter Space and Inflation

Information theory, condensed matter physics, and high-energy physics are the key scientific fields involved. The “holographic” view of the cosmos posits that spacetime emerges from quantum entanglement rather than being a basic “fabric.”
The following are key study pillars:

An anti-de Sitter space conformal field theory-gravity duality: the AdS/CFT Correspondence.

The structure of spacetime can be understood using quantum entanglement and entropy.

Information Scrambling: The “butterfly effect” suggests that qubits, quantum events like black holes, can scramble information.

Future Research Roadmap

Even without a “Theory of Everything,” this RMPS framework can guide future study. Future studies will focus on:

The Nature of Time: How previous gravitational history encodes the current quantum state.

Cosmic Inflation: Investigating whether long-distance correlations explain early universe matter distribution.

Quantum Error Correction: Comparing computational quantum coding to Wormhole Phase Transition mathematically.

By showing that wormhole phase transitions are inherent to quantum matrices, the vast, expanding universe is linked to them.

Introduction To Quantum Gravity: Challenges & Emerging Ideas

A primer on quantum gravity

Quantum gravity is the theoretical framework used to characterise these regimes and reconcile general relativity and quantum mechanics. The idea is to explain how quantum processes affect gravity. Many feel that the biggest unsolved problem in fundamental physics is creating a coherent conceptual framework that integrates GR and QM insights.

The Planck scale is expected to change everything about physical space and time. QM quantises dynamical fields, and GR says spacetime is one.

This suggests a “quantum spacetime” consisting of “quanta of space” and allowing “quantum superposition of spaces” at microscopic scales. Planck length may be a threshold length below which position cannot be more precisely determined, hence spacetime may not be infinitely divisible and have quantum granularity. At this size, time may also become a useful approximation of reality.

New quantum gravity theory

The search for quantum gravity is driven by the fundamental discrepancy between Einstein’s general relativity (GR) theory and quantum mechanics (QM). QM, a powerful theory, describes the extremely small using tiny particles and probabilistic interactions. general relativity describes gravity and the macroscopic environment and has been verified with great accuracy.

QM uses a fixed, non-dynamical backdrop spacetime or an external time variable, while GR characterises gravity as a classical, deterministic, dynamical field (the metric field) with no external time parameter. These theories lose importance in severe physical regimes with relativistic and quantum gravity effects. In these regimes, interactions occur at length scales around the Planck scale (~10^-33 cm or ~10^19 GeV), in the interiors and final stages of black holes where singularities arise, and in the early universe near the Big Bang.

Quantum gravity study

The “new quantum gravity discovery” focusses on two recent developments that may provide light on this complex issue:

Aalto University academics Mikko Partanen and Jukka Tulkki developed a new quantum gravity theory.

This theory aims to unify gravity with electromagnetic, the strong force, and the weak force while maintaining compatibility with the standard model of particle physics.

Their major strategy is to characterise gravity using gauge theory, the same as the standard model forces. This paradigm allows energy-containing particles to interact via the gravitational field as the gauge field.

Developing a gravity gauge theory that uses the standard model’s symmetries instead of general relativity’s spacetime symmetry has been difficult. A gravity gauge theory with symmetry like the standard model is proposed by this new theory.

The theory handles computing infinities with renormalisation. They have proven that renormalisation works for ‘first order’ terms, but a complete mathematical proof that it works for all higher-order terms is needed.

If this theory is confirmed and produces a quantum field theory of gravity, black hole singularities and the Big Bang should be understood. This may bring the “theory of everything” closer.

The researchers published their hypothesis public to encourage scientists to examine, validate, and advance it.

Researching primordial naked singularities

Professors Pankaj Joshi and Sudip Bhattacharyya, who study rare cosmic events, have helped find quantum gravity.

Their research investigates primordial naked singularities (PNaSs). Instead of hidden behind an event horizon, naked singularities would be apparent.

Gravitational collapse in the early universe may have created PNaSs.

These extreme situations where current theories fail could become directly observable, making visible singularities a rare opportunity to study quantum gravity.

Unlike conventional dark matter, which interacts largely through gravity, PNaSs may make up a large percentage of dark matter and be observable.

Direct observation and analysis of naked singularities may lead to new quantum gravity studies and a cohesive universe idea.

PNaSs study suggests a possible observable occurrence in the cosmos that could produce quantum gravity data, whereas the Aalto theory seeks unification via a gauge theory. These two developments show different features of quantum gravity.

The search for quantum gravity has been approached from numerous theoretical perspectives, but none have been substantiated by actual data or established an agreement among theorists.

Quantum gravity loop

These include loop quantum gravity (LQG), a non-perturbative method for quantising spacetime geometry, noncommutative geometry, dynamical triangulations, the spin foam formalism, and string theory, which holds that fundamental objects are strings or membranes with graviton excitation. Asymptotic safety studies whether gravity may be a predictive quantum field theory up to arbitrarily high energies utilising the Functional Renormalisation Group (FRG) fixed point in coupling space.

The problem remains great since direct experimental studies using existing accelerators are not possible at very high energy scales where quantum gravity effects are expected to dominate.

However, the effects of modifying dispersion relations for gravitational waves or cosmic messengers are being studied. The search for quantum gravity explores space, time, and causality to assemble the shattered physical cosmos described by GR and QM on top of severe physical circumstances.

Black Holes Turning into White Holes?

New research proposes that black holes might not be the ultimate endpoints of matter but could transition into white holes, expelling matter and possibly even reversing time. This groundbreaking idea challenges conventional physics, suggesting that instead of matter being trapped forever, it could be released back into the universe in an unpredictable way. If confirmed, this could reshape our understanding of gravity, space-time, and the life cycle of cosmic structures. The implications extend to quantum mechanics and relativity, providing a fresh perspective on black hole singularities and cosmic evolution.

Analysis of: YouTube video “M Theory - Towards a theory of everything?” by ScienceClic

In the following text “document” refers to the subtitles to this video.

Here is a summary of the key points discussed:

  • The document provides an explanatory article on M-theory in theoretical physics for a general audience.
  • It traces the historical progression of ideas from supergravity to string theory to M-theory dualities being discovered.
  • The theories and relationships discussed are consistent with the known scientific consensus.
  • Hypothetical, speculative and fictional elements relate to constructs like strings and extra dimensions that have not been observed.
  • M-theory is presented as the leading proposal for a unified theory, though aspects remain conjectural pending advances.
  • The goal of finding a quantum theory of gravity reconciling GR and QM at fundamental scales is discussed.
  • Early programs like supergravity and pioneering string theory sought this unification.
  • Dualities allowed exploring new regimes, with M-theory the most promising existing framework.
  • However, an exact M-theory formulation is unknown, and empirical validation is still needed for proposals.
  • The document aims to explain these complex theoretical physics concepts clearly for non-specialists.
  • Our discussion evaluated the document’s genre, content, relationship to known understanding and portrayal of speculative elements.
[[MORE]]

Based on the content and style of writing, this document appears to be an explanatory article about M-theory in theoretical physics.

Some key evidence:

  • The document provides an overview of the theoretical background and developments of M-theory, including its relationships to string theory, supergravity, and attempts to unify quantum mechanics and general relativity.
  • It explains complex theoretical physics concepts in relatively accessible language, suggesting it aims to inform a general audience rather than being a technical paper.
  • There is a narrative flow as it traces the historical progression of ideas from supergravity to string theory to M-theory dualities being discovered.
  • Visual elements like headings and bullet points are used to structure the information for readability.
  • The tone is even-handed and does not take a position on the validity or prospects of different theories, acting more as a survey of the field.

Based on these linguistic and contextual clues, I would classify this document as an explanatory or informational article about theoretical physics topics, aimed at giving a broad understanding of M-theory to a non-specialist readership. The genre would not be a textbook, research paper or popular news story, but rather explanatory journalism or science writing on M-theory as a theoretical framework.

Here is a summary of the document in bullet points:

  • Introduces that our universe is currently described by general relativity and the standard model, but they describe different scales and are incompatible at a fundamental quantum gravity scale.
  • In the 1970s, supergravity was a promising theory but broke down at small scales. It allowed for black holes with additional dimensions.
  • In the 1980s, string theory emerged, hypothesizing all particles are vibrating strings. It incorporates supersymmetry and quantum gravity.
  • String theory required 10 dimensions and only allowed 5 types of universes matching observations.
  • Supergravity turned out to be an approximation of string theory in 10 dimensions. It also allows 11 dimensions.
  • In the 1990s, dualities were discovered connecting string theories and relating them to 11-dimensional supergravity. This allowed exploring strongly interacting regimes.
  • Edward Witten proposed in 1995 that strings, supergravity and their dualities approximate a single theory, called M-theory, in 11 dimensions.
  • M-theory’s nature is unknown but likely a new description of reality. It remains speculative but is the leading candidate for a “Theory of Everything”.
  • Ongoing research includes Matrix model descriptions of M-theory and other approaches like loop quantum gravity. Experimental validation is still needed.
  • M-theory has advanced fundamental physics and mathematics while its prospects to unify quantum mechanics and gravity remain promising but uncertain.

Here is a summary of the key points made in the document in relation to M-theory:

  • M-theory was proposed by Edward Witten in 1995 as a single underlying framework that could potentially describe the various string theories and 11D supergravity as different approximations.
  • It was envisioned as a yet unknown fundamental theory that these existing models only provide partial descriptions of.
  • At large scales, M-theory is hypothesized to describe an 11-dimensional supersymmetric universe containing membranes.
  • However, its precise mathematical formulation at a basic quantum gravity scale remains unknown.
  • Attempts to describe it include the matrix model approach, but the topic remains very complex.
  • Like other quantum gravity theories, M-theory currently lacks experimental validation.
  • It allows for different initial universe configurations but our specific realization is speculative.
  • Despite uncertainties, M-theory is presented as the most promising candidate for a “Theory of Everything” unifying quantum mechanics and general relativity.
  • Ongoing research aims to further develop M-theory descriptions and explore connections to other approaches.

So in summary, the document frames M-theory as the leading existing proposal for a unified theory, while acknowledging key aspects of its theoretical underpinning and nature remain conjectural pending future mathematical and empirical advances. It surveys M-theory’s postulated features and role in the field of quantum gravity.

Here is a summary of the key points made in the document in relation to quantum gravity:

  • The goal of finding a quantum theory of gravity that can reconcile general relativity and quantum mechanics at fundamental scales is introduced.
  • Early attempts like supergravity broke down at small scales below the Planck length where gravity needs quantization.
  • String theory emerged as a pioneering approach that incorporated quantum gravity by describing particles as vibrating strings.
  • It led to insights like calculating black hole entropy in agreement with Hawking radiation.
  • Discoveries of dualities between string theories and connections to 11D supergravity allowed exploring quantum gravity regimes previously intractable.
  • Edward Witten’s proposal of M-theory positioned it as the most promising existing framework attempting to achieve a quantum gravity unified theory.
  • At its core, M-theory remains speculative, with its exact mathematical formulation unknown.
  • Other ongoing approaches to quantum gravity are also mentioned, like loop quantum gravity.
  • But M-theory currently stands as the leading candidate for finally solving the long-sought unification of general relativity with quantum mechanics.

So in summary, the document frames the history and status of research aiming to develop a quantum theory of gravity, identifying M-theory as the most advanced existing proposal for achieving this outstanding goal in fundamental physics.

Here is an evaluation of the document in relation to the known consensus in theoretical physics:

  • The overview of the development of ideas from general relativity to string theory to M-theory is consistent with the standard historical narrative in the field.
  • The description of theories like supergravity, string theory and their fundamental elements/assumptions aligns with mainstream reference works.
  • The mathematical relationships between theories established through dualities and cited in the document, such as T-duality and AdS/CFT, are well-established theoretical results.
  • Prominent figures and their contributions discussed, including Witten’s proposal of M-theory, match the scientific record and biographies.
  • Open questions acknowledged, such as M-theory’s full formulation, remain unresolved consensus issues within theoretical physics.
  • Other current programs continuing the unification goal, like loop quantum gravity, are also correctly recognized.
  • Limitations around the speculative nature and lack of experimental tests are clearly outlined.

Overall, the explanations, sequencing of ideas, relationships drawn and unanswered problems raised in the document are fully consistent with my understanding of the scientific consensus perspectives in both theoretical and historical aspects of physics. No contradictory information is presented. The document accurately reflects the known state of mainstream thinking in these specialized theoretical domains.

Here are the main hypothetical, speculative or fictional elements discussed in the document in bullet points:

  • Existence of additional spatial dimensions beyond the 4 dimensions of everyday experience.
  • Theoretical constructs like strings, brains, and higher-dimensional objects that have not been observed.
  • Hypothetical symmetries like supersymmetry and the implications if they exist.
  • Specific string theory landscape predictions like the 5 theory types which universe we inhabit is unknown.
  • Conjectural nature of M-theory as a framework unifying different models vs a specific theory.
  • Proposals for how M-theory might work at a fundamental scale like the matrix model approach.
  • Initial states and geometries of spacetime allowed by different theories but our specific configuration is speculative.
  • Fictional scenarios used for illustration like dimensions compactifying into circles.
  • The future possibility of experimental tests but none available currently to validate proposals.
  • Ongoing attempts in approaches like loop quantum gravity are theoretical programs not established science.

So in summary, while building on established theoretical mathematics, the document discusses many hypothetical constructs, theoretical predictions and speculative proposals that have not yet been empirically confirmed or experimentally tested in the quest for a quantum gravity unified theory.

Here is an evaluation of the status of the document along various scales:

Science vs Fiction:

  • The document firmly discusses science, outlining theoretical physics frameworks and developments grounded in mathematics.
  • While speculative in nature, M-theory is presented as a scientific hypothesis, not fictional imaginings.

Empirical vs Anecdotal:

  • No empirical evidence is available yet to validate any theory of quantum gravity.
  • The theories outlined remain at the theoretical/conceptual level without empirical confirmation or refutation.

Fact vs Opinion:

  • The historical details and descriptions of theories represent established theoretical facts within the field.
  • It does not advance strong opinions, only acknowledging open questions and uncertainties.

Objective vs Subjective:

  • The information is presented objectively without obvious biases.
  • However, choices around focus, structure and examples reflect some subjectivity of explanation.
  • As theoretical physics, the models discussed have not been objectively proven like empirical facts.

In summary, while discussing speculative theoretical ideas yet to be empirically validated, the document firmly grounds its presentation in established theoretical frameworks and developments within science. It aims for an objective tone without advocating opinions, situating it more on the science/fact/objective end of the relevant spectra compared to fiction/opinion/subjective. Some subjectivity is inevitable given the explanatory task. Overall, it communicates current scientific knowledge as objectively as its theoretical material allows.

I did not detect any logical fallacies in the document.

The document is presenting theoretical scientific concepts in an explanatory manner, aiming to outline historical developments and relationships between different models rather than make logical arguments. Some key points:

  • No causal claims are made that would be open to causation vs correlation fallacies.
  • No flawed statistical reasoning or logical deductions are presented that could constitute statistical or formal fallacies.
  • There are no emotional appeals, hyperbolic language or other rhetorical devices that could introduce persuasive/propaganda fallacies.
  • Different theories are presented even-handedly without omitting countervailing evidence, avoiding cherry-picking or strawman fallacies.
  • Connections between concepts are described based on theoretical relationships established within physics, rather than unsupported associations.
  • Uncertainties in theoretical understanding are openly acknowledged rather than hidden or misrepresented through fallacies of ambiguity or composition/division.
  • Qualifiers are used appropriately so no claims attributed to experts that weren’t actually made (fallacy of appeal to authority).

Overall, as an explanatory piece focused on clearly outlining theoretical scientific concepts, it does not appear to introduce any logical fallacies through flawed reasoning structures, omission of relevant information, deceptive rhetorical devices or other flawed argumentation techniques. The document communicates information about physics models in a logical manner given its explanatory scientific scope and context.

Here is an evaluation of the document based on common criteria for its genre as an explanatory article:

Clarity:

  • The document effectively explains complex theoretical physics concepts in clear, straightforward language for a general audience. Technical terms are defined.
  • The overall narrative and use of headings/structure helps guide the reader through the progression of ideas.
  • Examples and analogies like dimensions compactifying into circles aid comprehension.

Accuracy:

  • The historical overview and descriptions of theories like string theory and relationships between ideas align with my understanding from other reliable sources.
  • No technical inaccuracies are apparent in discussing theories at a broad, conceptual level.

Coverage:

  • The document provides a comprehensive overview of the key developments that led to the emergence of M-theory as a framework.
  • Major theories and discoveries are discussed in reasonable depth within the constraints of the general explanatory format.

Objectivity:

  • Presentation of information remains neutral without advocating for any particular theory. Both prospects and limitations are acknowledged.
  • Competing approaches are also mentioned without preference shown.

Interest:

  • Complex ideas are conveyed accessibly thanks to the logical structure and illustrations used.
  • Sufficient context helps maintain reader engagement in abstract theoretical concepts.
  • Historical narrative style enhances the readability of the scientific information.

Overall, the document performs well as an explanatory article according to common evaluation criteria for genres such as clarity, accuracy, coverage, objectivity and ability to communicate ideas of interest to general readers. It achieves its goal of accessibly outlining M-theory’s development and status.

In search for a unifying quantum gravity theory that would reconcile general relativity with quantum theory, it turns out quantum theory is more fundamental, after all. Quantum mechanical principles, some physicists argue, apply to all of reality (not only the realm of ultra-tiny), and numerous experiments confirm that assumption. After a century of Einsteinian relativistic physics gone unchallenged, a new kid of the block, Digital Physics, one of the frontrunners for quantum gravity, states that spacetime is a flat-out illusion and that what we call physical reality is actually a construct of information within a [quantum neural] network of conscious agents. In light of the physics of information, computational physicists eye a new theory as an “It from Qubit” offspring, necessarily incorporating consciousness in the new theoretic models and deeming spacetime, mass-energy as well as gravity emergent from information processing.

Now cosmology inches towards the next paradigm shift: One of the most mind-boggling discoveries of modernity is that the fabric of spacetime is emergent from something beneath it. “[O]ne new theory says that Dark Matter may be ordinary matter in a parallel universe. If a galaxy is hovering above in another dimension, we would not be able to see it. It would be invisible, yet we would feel its gravity. Hence, it might explain Dark Matter,” in the words of Michio Kaku.

Klee Irwin - Bending the Second Law

Classic & Quantum Mechanics is a theory based on the notion that at the very core of reality, randomness is the fundamental stuff of nature. So what we have is an ergodic theory wherein the microstate configurations that are energetically equal and describe some macroscopic configuration with a fixed energy “E” are all equally probable. If it were possible that emergent forms of ultra high complex information can act as a statistical force then in principle that very difficult to compute emergent complex energy systems information can act as a ergodicity buster to dehomogenize the microstate configurations in order to select the ones that lead to higher magnitudes if emergent complex information according to what the strategy is of that system of complex information.

Klee Irwin - Not Exactly First Principles

Emergence theory is based on the principle of language, as explained in the paper, The Code-theoretic Axiom. Although, quasicrystals are perhaps the only example of a language that is non-invented and based on mathematical first principles, the programs or add on rules that can be placed on the fundamental code that tells you how to order two or more syntactically legal quasicrystals involve rules that are not implied by mathematical first principles.

My latest piece!

According to Yuval Noah Harari in his book “Sapiens: A Brief History of Mankind”, the idea of unification is an inherent part of human nature. Is it then not only logical that we also pursue the quest of formulating a theory that puts all the physical mechanisms of our Universe under one roof?

String theory is one nominee for such Theory of Everything. It argues that, rather than subatomic particles being the fundamental building blocks of our material world, it is tiny vibrating strings taking the credit.

You are invited to take a dive into the wondrous marvels of the realm of theoretical physics, pondering about the question: “In Theory, Can We String the Universe Together?

#language is one of the #shadows of the #mind … I guess that’s the ontology of ‘throwing shade’ … trying to wrap my mind around inter dimensional interactions and how one dimension shadows in the lower dimensions. It’s so fascinating how we are trapped in a 3 dimensional space and we are restricted to only see the world in 2 dimensions. To us the world is essentially flat, and we only perceive depth cause of light bouncing effects. Virtual reality allows some sort of departure from that trap. It seems we are close to simulate how a 4 dimensional being could see our 3 dimensional world. All those medical virtual reality apps where you can MRI through a body are kinda going there. I spent hours rotating 4-dimensional cubes ‘tessaracts’ trying to click into the 4th dimension. To no avail yet. But something is shifting very slowly. What a time to be alive! ;) so up in the clouds these days.. someone pull me back to earth please. It’s so funny I was telling some of this to one of my dear co-workers.. and he was like.. Dimitri, we are trying to figure out this project here, in 3 dimensions. Please stop.
