NATIONAL BESTSELLER • From one of the world’s leading physicists and author of the Pulitzer Prize finalist The Elegant Universe, comes “an astonishing ride” through the universe (The New York Times) that makes us look at reality in a completely different way. Space and time form the very fabric of the cosmos. Yet they remain among the most mysterious of concepts. Is space an entity? Why does time have a direction? Could the universe exist without space and time? Can we travel to the past? Greene has set himself a daunting task: to explain non-intuitive, mathematical concepts like String Theory, the Heisenberg Uncertainty Principle, and Inflationary Cosmology with analogies drawn from common experience. From Newton’s unchanging realm in which space and time are absolute, to Einstein’s fluid conception of spacetime, to quantum mechanics’ entangled arena where vastly distant objects can instantaneously coordinate their behavior, Greene takes us all, regardless of our scientific backgrounds, on an irresistible and revelatory journey to the new layers of reality that modern physics has discovered lying just beneath the surface of our everyday world.

Introduces the superstring theory that attempts to unite general relativity and quantum mechanics.

From the mind-bending realms of quantum mechanics to the awe-inspiring expanses of the cosmos, Greene delves into the cutting-edge theories and discoveries that shape our understanding of reality. With clarity and depth, this book offers a transformative perspective on the fabric of the cosmos, illuminating the profound connections between space, time, and the very essence of existence.

Please note: This is a companion version & not the original book. Sample Book Insights: #1 I grew up reading books in my father’s bookcase, and while I was never forbidden to read them, I never saw anyone take one down. The books were massive tomes that seemed almost fused to the shelves. But the one that stood out was The Myth of Sisyphus by Albert Camus. #2 I found it difficult to believe that scientific progress could make any difference to our assessment of life’s worth. If our experiences only paint a paltry portrait of reality, our appraisal of life would be thoroughly compromised. #3 Modern science has shown that human experience is often a misleading guide to the true nature of reality. The most important and influential of these revisions is the understanding of space and time, which has been shaped by modern physics. #4 Space and time are the two most important concepts in physics. They are the raw material underlying reality. Through his theories of relativity, Einstein revealed the principal role they play in the evolution of the universe.

The writer sets as fundamental features for the basic structure of the Universe, an inversely proportional rate of change of Space over Time. Since Space is 3-dimensional also Time must be 3-dimensional. Both Space and Time units are integers and propagate scalar; thus in all directions simultaneously, like a balloon. This differs from the scientific view that puts matter in a 3-dimensional Space with a 1-dimensional Time. Ratios smaller than the speed of light form our known Cosmos and are in this theory called the material sector. Ratios that are larger than the speed of light form a so-called cosmic sector. In the cosmic sector everything works inverse. The ratio of one unit of Space over one unit of Time is the speed of light, which in this interpretation thus also has 3-dimensions. As such the light speed in 1-dimension can be exceeded by explosive force, for instance for stars as nova and for galaxies as quasar. This moves matter over the sector boundaries. Thus there is a continuous exchange of matter between both sectors. The conclusion ultimately is that the Universe is not accelerating and did not start with a Big Bang, but is cyclic. On these foundations, the writer diverts at the end into a personal vision on metaphysical connotations.

The bestselling author of The Elegant Universe and The Fabric of the Cosmos tackles perhaps the most mind-bending question in modern physics and cosmology: Is our universe the only universe? There was a time when "universe" meant all there is. Everything. Yet, a number of theories are converging on the possibility that our universe may be but one among many parallel universes populating a vast multiverse. Here, Briane Greene, one of our foremost physicists and science writers, takes us on a breathtaking journey to a multiverse comprising an endless series of big bangs, a multiverse with duplicates of every one of us, a multiverse populated by vast sheets of spacetime, a multiverse in which all we consider real are holographic illusions, and even a multiverse made purely of math--and reveals the reality hidden within each. Using his trademark wit and precision, Greene presents a thrilling survey of cutting-edge physics and confronts the inevitable question: How can fundamental science progress if great swaths of reality lie beyond our reach? The Hidden Reality is a remarkable adventure through a world more vast and strange than anything we could have imagined.
