Meh, but probably not.</text></item></parent_chain><comment><author>marcosdumay</author><text>You can reconstruct every mathematical theory as information flow and restrictions. That&amp;#x27;s a property of mathematics (Turing found that), not physics.</text></comment>

You&amp;#x27;d effectively have an infinite number of bits in an infinitely dense space, which would potentially require infinite energy to flip.&lt;p&gt;But I suspect (on no basis whatsoever, except the fact that all previous metaphors have been wrong) that the &amp;quot;universe = Turing machine model&amp;quot; is wrong in some fundamental ways.&lt;p&gt;I have no idea what the universe is, but I&amp;#x27;m open to the possibility that it isn&amp;#x27;t &lt;i&gt;just&lt;/i&gt; an information processing system.</text></comment>
