I will provide my cliff notes answer to this question here, and add further references at the end. I have arrived at this answer through my approximately 20-years of research seeking answers to fundamental questions. Note that the ideas I present below are not original to me, but represent what I consider to be the most promising and satisfying results by contemporary thinkers.</div><div><br></div><div><br></div><div><b>How Come the Quantum?</b></div><div><b><br></b></div><div>When quantum mechanics was first formulated (approximately 100 years ago) physicists were shocked:</div><div><br></div><div>"Those who are not shocked when they first come across quantum theory cannot possibly have understood it." -- Niels Bohr</div><div>"I repeated to myself again and again the question: Can nature possibly be so absurd as it seemed to us in these atomic experiments?" -- Werner Heisenberg</div><div>"I think I can safely say that nobody understands quantum mechanics." -- Richard Feynman</div><div><br></div><div>And despite mulling over quantum mechanics for nearly a century, the mystery persisted. In 1998, John Archibald Wheeler wrote: "I have never been able to let go of questions like: How come existence? How come the quantum?" And he continued searching for an answer all his life.</div><div><br></div><div><b>Infinite Logic</b></div><div><br></div><div>In 1965, Richard Feynman wrote in his famous "<a href="https://archive.org/details/characterofphysi0000feyn/page/56/mode/2up?q=it+always+bothers+me" target="_blank" rel="noreferrer">The Character of Physical Law</a>" series:</div><div><br></div><div>"It always bothers me that, according to the laws as we understand them today, it takes a computing machine an infinite number of logical operations to figure out what goes on in no matter how tiny a region of space, and no matter how tiny a region of time. How can all that be going on in that tiny space? Why should it take an infinite amount of logic to figure out what one tiny piece of space/time is going to do?"</div><div><br></div><div>As the genius he was, Feyman figured out a way to turn this seeming problem into an advantage. In 1982 he <a href="https://www.fisica.net/computacaoquantica/richard_feynman_simulating_physics_with_computers.pdf" target="_blank" rel="noreferrer">proposed</a> that this property could be exploited to build computers that could simulate physics much more efficiently. And in 1985, David Deutsch <a href="http://user.it.uu.se/~hessmo/QI/notes/deutsch85.pdf" target="_blank" rel="noreferrer">described</a> how such a "quantum computer" could be built.</div><div><br></div><div>But we know the bounds on regular, or "classical" computation. Seth Lloyd <a href="https://arxiv.org/abs/quant-ph/9908043" target="_blank" rel="noreferrer">calculated</a> the entire computational capacity of the entire universe over its entire history, to be around 10^120 operations. And yet, a single quantum computer, one that in principle, could sit on a desk, can perform more operations in a few seconds than all the matter in the universe could over the billions of years of its existence. A quantum computer with 300 qubits, could simultaneously process 2^300 distinct states. This not only far exceeds the 10^120 operations, it even exceeds the 2^265 atoms in the observable universe.</div><div><br></div><div>Where is all this computational capacity coming from?</div><div><br></div><div>Deutsch <a href="https://www.kurzweilai.net/taming-the-multiverse" target="_blank" rel="noreferrer">offered</a> his opinion on this question:</div><div><br></div><div>"Since the Universe as we see it lacks the computational resources to do the calculations, where are they being done? It can only be in other universes. Quantum computers share information with huge numbers of versions of themselves throughout the multiverse."<br><br></div><div>But this only poses deeper mysteries: Why should reality consist of a myriad of other universes, why should there be any form of interaction/information sharing (i.e. interference) between them, and where does all the computation necessary to support all those universes come from?</div><div><br></div><div><b>What underlies Matter?</b></div><div><br></div><div>It is only very recently, in the past few decades, that any progress was made on these questions, and we now arguably have empirical evidence to support a viable answer to this question.</div><div><br></div><div>Wheeler was one of the first modern physicists to speculate that matter was not the most fundamental thing, writing: "Now I am in the grip of a new vision, that Everything is Information. The more I have pondered the mystery of the quantum and our strange ability to comprehend this world in which we live, the more I see possible fundamental roles for logic and information as the bedrock of physical theory." He termed this theory "<a href="https://philpapers.org/archive/WHEIPQ.pdf" target="_blank" rel="noreferrer">it from bit</a>" in 1989.</div></div></div></div></blockquote><div><br></div><div> FYI, I took this paragraph and added it to the "it from bit?" topic on Canonizer</div><div><a href="https://canonizer.com/topic/138-It-from-Bit/1-Agreement?is_tree_open=0&as_of=includereview&asof=review" target="_blank" rel="noreferrer">https://canonizer.com/topic/138-It-from-Bit/1-Agreement?is_tree_open=0&as_of=includereview&asof=review</a></div></div></div></blockquote></div></div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto">Excellent!

He writes: "The explanation of quantum mechanics as describing the process of observation within a plenitude of possibilities is for me the pinnacle of achievement of the paradigm discussed in this book. I can now say that I understand quantum mechanics. So when I say I understand quantum mechanics, I mean that I know that the first three postulates are directly consequences of us being observers. Quantum mechanics is simply a theory of observation!"</div><div><br></div><div>Then in 2017, the quantum physicist Markus Müller <a href="https://arxiv.org/abs/1712.01826" target="_blank" rel="noreferrer">detailed</a> how starting from the assumption state that all observer states are generated algorithmically (i.e. through computation) he could show that most observers will find themselves in universes having the property of time, an identifiable beginning, and will be governed by simple, computable, probabilistic laws. All of these predictions align with observations of our universe and its properties.</div><div><br></div><div>In 2021, the computer scientist Stephen Wolfram published a theory of "<a href="https://writings.stephenwolfram.com/2021/11/the-concept-of-the-ruliad/" target="_blank" rel="noreferrer">The Ruliad</a>" -- a computational structure that represents all possible computational rules playing out in all possible ways. According to Wolfram, all computations playing out in all possible ways directly leads to observers who will see a universe with the second law of thermodynamics, general relativity, and even quantum mechanics. Regarding the emergence of quantum mechanics, Wolfram <a href="https://writings.stephenwolfram.com/2021/03/what-is-consciousness-some-new-perspectives-from-our-physics-project/" target="_blank" rel="noreferrer">writes</a>, "Does the observer 'create' the quantum mechanics? In some sense, yes. Just as in the spacetime case, the multiway graph has all sorts of computationally irreducible things going on.

This one assumption (that all computations exist) produces so many verifiable predictions motivates us to take it seriously.</div><div><br></div><div>But why do all computations exist? On what do they <i>run</i>? To this question, one answer appeals most to me: infinite, absolute, eternal, uncreated, mathematical truth.</div><div><br></div><div>In a resolution to a mathematical problem <a href="https://www.ams.org/journals/bull/1902-08-10/S0002-9904-1902-00923-3/S0002-9904-1902-00923-3.pdf" target="_blank" rel="noreferrer">posed</a> by David Hilbert at the turn of the century, <a href="http://www.scholarpedia.org/article/Matiyasevich_theorem" target="_blank" rel="noreferrer">four mathematicians proved</a> in 1970 that every computation exists within pure mathematics as a true statement about an <a href="https://en.wikipedia.org/wiki/Diophantine_equation" target="_blank" rel="noreferrer">equation involving natural numbers</a>. This may sound like an obscure and trivial fact, but I think it has incredible consequences. Consider: It means there is an equation that picks chess moves like Deep Blue, there’s an equation that does your taxes like TurboTax, there’s yet another equation that does spellchecking like Microsoft Word. But of course, these are not the only equations that exist in math. There would be equations representing every computer game, as well as every possible way of playing them. There would be programs that simulate the physics of our universe, accurate down to the detail of every particle. And there would be simulations of every possible variation that must exist.</div><div><br></div><div>All these computations fall out as a consequence of there existing objective mathematical truth concerning numbers and their relations. One way to think about all this, is that we (an the multiverse we find ourselves in) exist for the same reason that "2 + 2 = 4".</div><div><br></div><div>So if one can accept the self-existent truth of "2 + 2 = 4", it can be demonstrated that one must further accept truths concerning other equations, equations whose truths concern all computational histories and all simulated realities playing out in all possible ways.</div><div><br></div><div>This is an answer to where our reality, consisting of infinite computation, may come from. It is the most elegant and convincing answer I have encountered in all my research into this question. And so, at last, we have a way to explain fully how quantum computers work, why we're in a quantum multiverse, and what underlies the infinite computations supporting that reality. We have distilled the explanation to a final "because" which throws up no further "whys" as ultimately, the answer reduces to "because 2 + 2 = 4."<br><br></div><div><br></div><div>Jason</div><div><br></div><div>Along with the references I included as links throughout this e-mail, you can find further details and explanations here:</div><div><ul><li style="margin-left:15px">My full article on "Why does anything exist?"
