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

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 successfully… Expand

A Metaphorical Chart of Our Mathematical Ontology

- Computer Science
- 2015

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

- Physics

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 remain… Expand

Towards a theory of universes: structure theory and the mathematical universe hypothesis

- Computer Science
- Synthese
- 2015

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.

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 from… Expand

DEAN RICKLES ON EXPLAINING EXISTENCE

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 genuinely… Expand

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 physical… Expand

Why Physicalism Seems to Be (and Is) Incompatible with Intentionality

- Philosophy
- 2020

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 and… Expand

The Computable Universe Hypothesis

- Mathematics, Computer Science
- ArXiv
- 2010

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

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 of… Expand

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 physical… Expand
