Parallel Universes and Epubالعبود»«الياس سعدي»، «ماجدة علي علي»«هادي ابراهيم»، «سامي اكايا»«ماجد حنّا»، «أحمد»« محمد زهرة»، «منصور التميمي»اخراج فني 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
