&gt; Mathematics is a human language for studying the structure of various experiences<p>I think you are getting hung up on the semiotics of mathematics which is indeed a human construct. The idea of &quot;1 + 1 = 2&quot; is true no matter how (or if) you represent the idea.<p>&gt;  saying that it&#x27;s a &quot;mathematical structure&quot; is just saying that it&#x27;s a structure that humans can apply mathematics to model<p>That&#x27;s not what the theory says (AFAIK). The mathematical universe hypothesis says that there is nothing in the universe, it&#x27;s all just mathematics.<p>Edit: Think about it this way: if you could simulate a universe and in that simulated universe you modeled people and all the stuff around them, what would you tell those simulated people with their simulated free well what a table is made out of? It&#x27;s all mathematics, right?
