So my buddy Ryan introduced me and Jo to his new girlfriend this past weekend and she's a mathematician who is clearly not very good at it because Ryan with a girlfriend doesn't add up ZING so I was like Do you think we're all avatars in a big futuristic game of The Sims? and her face just lit up like I've been waiting for someone to ask me this all my life She is adorable and we geeked out about parallel universes for like half an hour while Ryan and Jo made big exaggerated sighing noises Hey just let us know when you want to talk about something that's not the nerdiest bullshit ever Okay that will be never because we're best friends now I said that Ryan's girlfriend probably thinks I'm just okayAnd that's why this is a great book because it's wicked fun to talk about all this shit Whee multiverse says my avatar You ever hear that theory that once computers get to the same complexity as human brains they'll sortof automatically develop consciousness? Scientists think that because otherwise there's something we totally don't get about consciousness and who needs that? Lame So here's the thinking if that's true then we'll probably have it by around 2020 And once we have artificial intelligence what are we going to do with it? Put it in video games obviously We know this because we are people and that's the kind of shit people do So we're going to have these virtual worlds just like The Sims except the people in it will actually be aware and we'll all play these virtual world games on our Playstations And that means there'll be like thousands of virtual worlds with conscious inventions in them interacting with each other And that means that only one of all the worlds featuring conscious beings is the real one; the rest are video games And that means that odds are the world you're reading this in isn't the real one Just statistically it's likely that you're a collection of sprites that some pimply teenager created near arbitrary rules forThat's nuts right? Crazy nuts Batty Among other things it means that there's a God after all because whatever pimply teenager is playing this particular game that I'm in can delete this game whenever he wants or make an asteroid hit Brazil or make Kate Middleton show her boobs For most intents and purposes that is GodAlso it raises this uestion is Pimply God doing a good job? Is this particular world a good one? Or is he an asshole? If all the sim worlds were ranked from most pleasant to least where would this one fall? If you set a bunch of AIs up in a fairly nice place will they probably fight? Is there like an Aggression Slider so you can make us or less likely to fight? What would this world be like if Pimply God was deep in the throes of puberty? Or is this it?Ryan's girlfriend thinks we are most likely virtual seriously serious people think this whole thing makes perfect sense but I think I lost her with the puberty bitThis is the craziest and last theory in Hidden Reality There are eight others and they're not mutually exclusive The least crazy theory is that space is infinite and infinite is a lot so somewhere beyond what we can ever see given the speed of light there will be a world just like ours and infinite worlds just like ours because infinite means everything including a world where everything happens and will happen exactly like it has and will in this world you're in now with the sole exception that instead of reading this review you personally decided to make a sandwich Infinite is a lotEverything in Hidden Reality is theoretical so there's no pressing reason for you to read this book Or any of the rest of the books while we're on the subject Pimply God read Shakespeare and was like Ha that's cool it rhymes and everything sometimes I mean it's terrible compared to real life literature but not bad for artificial intelligence But whee multiverse Four stars says my avatar as Pimply God happens to narrow his focus on my apartment just to see what's going on near Boston and says That sim there just called me pimply Here's a random asteroid how ya like me n

Outstanding update of the current status of modern physics and the projections of parallel universes from various advances I would have loved to have Greene for a teacher in college The tour is suitable for laymen with some understanding of physics as he provides plenty of concrete examples to explain challenging concepts and gives an opportunity to skip technical sections For the knowledgeable reader a copious appendix is available replete with the relevant math euations Greene works his way through the history and logic behind eight different models of parallel universes and their status in terms of development and progress toward potential verifiability The only one that I was really familiar with from a college course on uantum physics 40 years ago Everett’s 1956 Many Worlds Hypothesis is the only one that really bothers me with its continual “splitting” off of parallel realities at every point where uncertain outcomes like the position of an object is resolved Greene makes it clear how the interpretation is simpler and elegant than Bohr’s interpretation The latter calls for the probability wave of a particle to mysteriously collapses when it is detected or interacted with effectively throwing out Schroedinger’s euations out whenever a “measurement” is made and restricting their applicability only to very small objects Despite Occam’s Razor favoring Everett’s hypothesis the uantum mechanics euations apply deterministically at all times the interpretation of possible alternative states as each being somehow “real” has always been too absurd to be true to me It’s a relief then that there is still scientific resistance to the notion and demonstrations of problems with the theory Greene notes “I don't expect theoretical or experimental consensus to come in my lifetime concerning which version of reality a single universe a multiverse something else entirely—uantum mechanics embodies”The other theories are fascinating and do not call for my alternative choices to have an existence in parallel universes It was great to get a perspective on the excitement and challenges with string theory and its promise for helping unify the gravitational force with the other forces already in the fold of uantum field theory The discovery that our universe is undergoing an acceleration in its expansion and the need for some kind of anti gravity force “dark energy” was a shock to me so the recent successes of the theory of empty space having an “inflaton” field was satisfying to read about Greene’s coverage of recent work on the meaning of entropy and information in physical systems was also a pleasure for meFor a sense of the content of this book here is a thumbnail sketch of the seven other parallel universe theories covered as laid out in Greene’s summary chapter uilted Multiverse Conditions in an infinite universe necessarily repeat across space yielding parallel worlds Inflationary Multiverse Eternal cosmological inflation yields an enormous network of bubble universes of which our universe would be one Brane Multiverse In stringM theory’s braneworld scenario our universe exists on one three dimensional “brane” which floats in a higher dimensional expanse potentially populated by other branes—other parallel universes Landscape Multiverse By combining cosmology and string theory the many different shapes for string theory’s extra dimensions give rise to many different bubble universes Holographic Multiverse The holographic principle asserts that our universe is exactly mirrored by phenomena taking place on a distant boundary surface a physically euivalent parallel universe Simulated Multiverse Technological leaps suggest that simulated universes may one day be possible Ultimate Multiverse The principle of fecundity asserts that every possible universe is a real universeThese universes instantiate all possible mathematical euationsThe summary chapter was also satisfying to me in attempting to address the following uestions Is the Copernican pattern fundamental? Following the 500 year trend that ”the we understand the less central we appear” we now approach the perspective that “our universe itself may not be central to any cosmic order” Can scientific theories that invoke a multiverse be tested? The worry is that ”by invoking a multiverse we enter the domain of theories that can’t be tested” He argues that well founded multiverse theories should be able to make predictions which are likely to be testable in our own universe and hence falsifiable How does the multiverse affect the nature of scientific explanation? Traditional approaches for physics aims to use mathematical expressions of physical laws and a set of constants and initial conditions to project what measurable things will be like at a subseuent time Multiverse theories usefully explore variability in these conditions and laws which must be accepted as a given in a single universe theory Should we believe mathematics? Based on past progress mathematical theories have had a huge impact on guiding science toward hidden truth Despite problems in testing the multiverse theories pushing on them is likely to lead to progress
