doc Ú Something Deeply Hidden uantum Worlds and the Emergence of Spacetime ✓ Sean Carroll Of you are generated thousands of times per second The Many Worlds Theory of uantum behavior says that every time there is a uantum event a world splits off with everything in it the same except in that other world the uantum event didn't happen Step by step in Carroll's uniuely lucid way he tackles the major objections to this otherworldly revelation until his case is inescapably established Rarely does a book so fully reorganize how we think about our place Deeply Hidden uantum Worlds and Kindle in the universe We are on the threshold of a new understanding of where we are in the cosmos and what we are made TL;DR Sean Carroll’s Something Deeply Hidden tackles the difficult many worlds theories of uantum mechanics It’s weird; it’s funny; it’s deeply philosophical and worth reading Highly recommendedDisclaimer I received a free copy of this as an ebook from the publisher in exchange for an honest review Find this and other reviews at my website Primmlifecom Review According to uantum mechanics it’s entirely possible that there are multiple copies of you reading multiple copies of this review The many worlds approach to uantum mechanics says that the world decoheres into various branches Branching reality is a difficult subject but it is one that makes sense when interpreting exactly what uantum physics represent Physicist author and podcaster Sean Carroll attempts to explain these subtle and difficult philosophical uestions in his latest book Something Deeply Hidden from Dutton This is a book of big ideas explained to an audience of anyone It doesn’t spoon feed the reader answers but nor does it put concepts too far out of reach For anyone interested in uantum mechanics this is a must read Review Something Deeply Hidden I’m a fan of Sean Carroll I like his podcasts and his appearances on Joe Rogan’s podcast He’s entertaining while still conveying complex knowledge So this review is biased from the start I don’t understand uantum mechanics and for most of my studies I’ve been told I don’t need to understand it because the math works It’s an odd way to approach physics To uote Richard Feynman “I think I can safely say that nobody understands uantum mechanics” Certain physicists like Sean Carroll have decided to change that Something Deeply Hidden largely succeeds for our current best understanding It doesn’t rely on the fact that the math works out; it attempts to explain reality which was physics original purposeThe book reads well; it’s not full of euations though there are some Dr Carroll’s style of explanation is clear enough without euations He’s funny and fills the book with good examples and easy to follow illustrations Dr Carroll lays down a foundation of uantum mechanics history before moving onto cutting edge physics and then to the weird stuff Something Deeply Hidden is an intensely philosophical book that I’m still thinking aboutThe book focuses on Schrödinger’s euation and the Everettian interpretation which is also known as the many worlds interpretation In short Schrödinger’s euation describes the wave function of the universe and there is no collapsing of the euation Instead of superpositions collapsing into a measured reality the measurement causes a branching of the universe Let me repeat that a branching of the universe One where outcome A happens and another where outcome B happens And guess what we branch when the universe does as well The Many Worlds Interpretation Decoherence branching and superposition are difficult concepts to understand Honestly I’m not sure I grasp it fully Dr Carroll does a good job explaining it in a way that I could start to understand This is a book that I will have to reread The idea that the universe branches has long been a popular idea in science fiction see the TV show Sliders But it’s much complex than simply a person’s decision causes the universe to split In fact Dr Carroll deliberately debunks this idea The universe branches but an individual’s decision doesn’t cause the branchingDr Carroll explains the many worlds interpretation in plain terms that at the same time make you scratch your head In Chapter Seven Dr Carroll writes a short story that’s a dialogue between father and daughter physicists In a way it reminded me of What We Talk About When We Talk About Love by Raymond Carver This chapter was unexpected yet effective in conveying difficult topics around probability It was an odd chapter in a physics nonfiction book but it helped convey the information Something Deeply Hidden is well written Part Three Something Deeply Hidden is organized into three parts with a prologue epilogue and appendix I kept up easily with part one; part two stretched the limits of my intellect; and part three simultaneously blew my mind and broke my brain I don’t think I can adeuately review this section without reading it again And I will definitely read it again In my review copy one of the chapters in part three is titled “Breathing in Empty Space” A chapter title like that deserves re reading Multiple Me's One conseuence of branching is that when the universe decoheres and branches so does the person In other words there are many copies of each of us on various branches out in the multiverse Maybe Dr Carroll treats this as no big deal and really after thinking about it for a while it isn’t Since we can’t interact with these other branches contemplating the other me’s that exist is much the same as contemplating how many angels dance on the head of a pin But I never did shake the weirdness of me branching with the universeThis branching has direct conseuences to conservation of energy and the concept of entropy I’m not entirely convinced of the answer provided but it’s an interesting answer This is one of the rare moments in the book where I don’t think the answer conveys a physical meaning Or at the very least one that I can understand If the universe branches enough does that mean it’s possible to lower the energy of the many worlds to almost zero If so what happens to all the me’s in those branches Competing Theories Dr Carroll states plainly that he subscribes to Hugh Everett III’s interpretation of uantum mechanics But he does devote time to competing theories and gives them fair treatment Then he explains why he thinks the alternate interpretations are wrong but in respectful manner Maybe I’ve been reading too much politics lately but this was really refreshing It’s important to see a thoughtful summary of and argument against a competing philosophy without a need to ‘win’ – whatever that means in physics circlesThis section also serves as a starter for investigating about the interpretation of uantum mechanics In this section I learned the phrase uantum Bayesianism which is just fun to say Dr Carroll’s description is uite interesting and I might look into the topic in the future Conclusion Sean Carroll’s Something Deeply Hidden broke my brain in the best way possible This insightful philosophical book explains difficult complex concepts in understandable language Based on the arguments I’m now an Everettian convert Somewhere out in the multiverse there’s an Eric writing a better review of this book In a different branch there’s an Eric who didn’t get to read this book and he’s all the poorer for it9 out of 10

Something Deeply Hidden uantum Worlds and the Emergence of SpacetimeTs haven’t even recognized the uncomfortable truth physics has been in crisis since uantum mechanics has always had obvious gaps which have come to be simply ignored Science popularizers keep telling us how weird it is how impossible it is to understand Academics discourage students from working on the dead end of uantum foundations Putting his professional reputation on the line with this audacious yet entirely reasonable book Carroll says that the crisis can now come to an end We just have to accept that there is than one of us in the universe There are many many Sean Carrolls Many of every one of us Copies This book puts up an intellectual defense of the many worlds interpretation of uantum Mechanics first proposed by Hugh Everett III in 1957 I was sold on this interpretation a long time ago but I like the way Carroll presents his case The Everettian view is the most conservative metaphysical view of uantum mechanics with the fewest ad hoc additions to sueeze the theory into our common sense notions Because of this the conclusions of this conservative framework are the most counterintuitive shocking commonsense so radically that many will balk at it The many worlds interpretation leads to the weird idea that every possible measurement of with a probability is realized in myriad branching realities when a uantum measurement takes place and all the time in the universe Carroll shows that the simplest assumption set leads to this conclusion and one may be tempted to dismiss this as repugnant but that is where the simplest understanding of M leads Maybe it is a reductio absurdum and a bridge too far but commonsense has taken a beating in 20th and 21st century physics and mathematics maybe this time we might not want to listen to our gut Carroll also talks about a newer approach to uantum gravity In the past we worked with relativity and tried to uantize it Carroll wants to start with uantum mechanics and uantum entanglement and try to get relativistic spacetime to fall out of it Approaching uantum gravity from the uantum end rather than the gravity end I always enjoyed Carroll's popularizations and this one works for me as well as his othersHere is the author speaking for himselfhttpswwwyoutubecomwatchvjHLfMHe boils Many Worlds into the simplest terms in this lecture in PennsylvaniahttpswwwyoutubecomwatchvMScOpThis is the best video I've seen so far explaining Many WorldshttpswwwyoutubecomwatchvkTXTP
