Mathematics is a human language for studying the structure of various experiences. To say the universe &quot;is&quot; mathematics without saying what mathematics is doesn&#x27;t really say much at all. You might as well say it&#x27;s magic.<p>And, 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. So there&#x27;s really no mechanism for this to be true, except in the trivial &quot;the universe has structure&quot; sense, which also tells you (basically) nothing, because humans can&#x27;t even perceive things that don&#x27;t have structure, nor can we reason about them.
