Abstract I explore physics implications of the External Reality Hypothesis (ERH) that there exists an external physical reality completely independent of us humans. I argue that with a sufficiently broad definition of mathematics, it implies the Mathematical Universe Hypothesis (MUH) that our physical world is an abstract mathematical structure. I discuss various implications of the ERH and MUH, ranging from standard physics topics like symmetries, irreducible representations, units, free… Expand

Geometrical Universe Hypothesis
Max Tegmark, exploring implications of the External Reality Hypothesis (ERH) that there exists an external physical reality completely independent of us humans, claims that physics is so successfullyExpand
A Metaphorical Chart of Our Mathematical Ontology
This is my vision of the relationship between mathematics and physics based on my observations on the nature of physical laws and mathematical structures, where a structure from higher category theory is the central piece from which all else stems. Expand
Physical Relativism as an Interpretation of Existence
Despite the success of modern physics in formulating mathematical theories that can predict the outcome of quantum-scale experiments, the physical interpretations of these theories remainExpand
Towards a theory of universes: structure theory and the mathematical universe hypothesis
The mathematical universe hypothesis as developed by Max Tegmark with the axioms of Stewart Shapiro’s structure theory are combined to form a theory, the Theory of the Structural Multiverse (TSM), which is demonstrated to be an empirically significant scientific theory that is foundational to and continuous with the rest of the scientific image.

My God, It’s Full of Clones: Living in a Mathematical Universe
Imagine there’s only math—physics is nothing more than mathematics, we are self-aware mathematical substructures, and our physical universe is nothing more than a mathematical structure “seen fromExpand
What are the limits of physics’ explanatory power? Can physics explain everything? In this paper I discuss a somewhat broader question: can physics explain existence itself? I argue that genuinelyExpand
The Informational Conception and Basic Physics
In our previous arXiv papers (“The Information and the Matter”, v1, v5; more systematically the informational conception is presented in the paper “The Information as Absolute”, 2014) it wasExpand
Physics from scratch. Letter on M. Tegmark's ``The Mathematical Universe''
In a recent article, M. Tegmark poses the hypothesis that our known universe is a ``baggage free'' mathematical structure among many other possible ones, which also correspond to other physicalExpand
Why Physicalism Seems to Be (and Is) Incompatible with Intentionality
There is a long history of philosophical intuition that the human mind must be more than physical or mechanical. I argue that this intuition arises from the perfect “transparency” of physical andExpand
The Computable Universe Hypothesis
It is shown how computable physical models on effective topological spaces can be formulated using the theory of type-two effectivity (TTE), which allows for a precise formalization of the computable universe hypothesis--the claim that all the laws of physics are computable. Expand


On Math, Matter and Mind
We discuss the nature of reality in the ontological context of Penrose’s math-matter-mind triangle. The triangle suggests the circularity of the widespread view that math arises from the mind, theExpand
The structure of the world from pure numbers
I investigate the relationship between physics and mathematics. I argue that physics can shed light on the proper foundations of mathematics, and that the nature of number can constrain the nature ofExpand
Is “the Theory of Everything” Merely the Ultimate Ensemble Theory?☆
Abstract We discuss some physical consequences of what might be called “the ultimate ensemble theory,”, where not only worlds corresponding to say different sets of initial data or different physicalExpand
83 years of general relativity and cosmology: progress and problems
This paper considers the evolution of the relation between gravitational theory and cosmology from the development of the first simple quantitative cosmological models in 1917 to the sophisticationExpand
Multiverses and physical cosmology
The idea of a multiverse – an ensemble of universes – has received increasing attention in cosmology, both as the outcome of the originating process that generated our own universe, and as anExpand
Does the universe in fact contain almost no information?
At first sight, an accurate description of the state of the universe appears to require a mind-bogglingly large and perhaps even infinite amount of information, even if we restrict our attention to aExpand
Why Occam’S Razor
Ensemble theories have received a lot of interest recently as a means of explaining a lot of the detailed complexity observed in reality by a vastly simpler description “every possibility exists” andExpand
Feynman-Weinberg Quantum Gravity and the Extended Standard Model as a Theory of Everything
I argue that the (extended) Standard Model (SM) of particle physics and the renormalizable Feynman-Weinberg theory of quantum gravity comprise a theory of everything. I show that imposing theExpand
Towards a Coherent Theory of Physics and Mathematics
As an approach to a Theory of Everything a framework for developing a coherent theory of mathematics and physics together is described. The main characteristic of such a theory is discussed: theExpand
