WHY GOD COULD NOT CREATE THE UNIVERSE WITH A DIFFERENT DIMENSION EVEN IF IT WANTED TO or perhaps anything else. Perhaps the universe must be the way it is. It seems that what is omnipotent is mathematics, elementary arithmetic, just counting. Yet even mathematics is not powerful enough to create a universe¿there are just too many conditions, conflicting. Existence is impossible. Beyond that for there to be structure is quite inconceivable. But the universe does exist, there are galaxies, stars, even the possibility of life. That life is possible merely allows it to exist but only with the greatest good fortune does it actually occur. Intelligence is vastly less likely, ability and technology far more improbable. That we are, what we are, seem so strange, inconceivable, that we are left merely with wonder¿and, as we seem unable to realize, the need for the deepest care, responsibility and gratitude. We have been given by the unbelievable benevolence of chance, no life, but life with the most wondrous part of the universe, the ability to think, to know, to create, to wonder¿and thus the demand that we use our most awesome gifts to protect them, to protect and preserve the world in which they exist, and the life, likely so rare if not unique in the universe, which has received these astounding favors of chance, that has been given by nature its most exalted constituents. What we are requires that we enhance what we are, what we are part of, to see, understand and be grateful. An exploration of the precise conditions required for the existence of humans in the universe. ...the author does an admirable job delineating the laws of physics without becoming too bogged down in complicated jargon, and he maintains a sense of wonder about the unique and random nature of the universe. He repeatedly celebrates our highly improbable achievements as a species, marveling at our ability to use the language of abstract mathematics to unravel the mysteries of existence. ... the prevailing tone of the narrative is clear and confident, marked by a meticulous attention to detail. An...often fascinating journey through the history of the universe and mankind. -Kirkus Discoveries

Max Tegmark leads us on an astonishing journey through past, present and future, and through the physics, astronomy and mathematics that are the foundation of his work, most particularly his hypothesis that our physical reality is a mathematical structure and his theory of the ultimate multiverse. In a dazzling combination of both popular and groundbreaking science, he not only helps us grasp his often mind-boggling theories, but he also shares with us some of the often surprising triumphs and disappointments that have shaped his life as a scientist. Fascinating from first to last—this is a book that has already prompted the attention and admiration of some of the most prominent scientists and mathematicians.

A complete introduction to the heavens through the tales of these 21 key stars.

A scientist who has been originally trained as a biologist and has always been interested in life on Earth and outside the universe proposes a project to investigate the presence of a different form of life in the universe. This scientist has fifty years’ experiences in different aspects of life. He also has updated knowledge about our planet, our galaxy, our universe, and other possible universes. He is familiar with the latest findings and improvements in the field of theoretical physics and investigations that had been so far done and had been focused on finding lives in other solar systems. To obtain approval and funds for his project, he contacts one of the highly advanced scientific societies in the United States and presents a series of scientific talks. In his presentations, he states, “Why, out of over two million different species living on Earth, only humans (Homo sapiens) are considered the most advanced one, and why, if we are looking for lives outside our planet, are we always looking for some sort of humanlike creature?” He tries to convince the scientists that there must be billions of other types of beings in our universe and other universes. These different types of lives can be much smaller or much larger than us. They can be much more intelligent and highly advanced creatures when compared with humans on Earth. They may not necessarily need water, moderate temperature, simple energy sources, etc. They may not reproduce the way that we do and may not even die, which is the final chapter in our lives. Finally, he will convince several distinguished scientists to support his project. With the help of several additional young scientists who are experts in different fields of science, in a highly advanced scientific institution, finally they prove that lives could be much simpler and at the same time more advanced than us. By doing extensive research, they finally find creatures that are extremely smaller than us and start communicating with them. Although this book presents a science fiction story, the processes by which the scientists discover these small creatures are completely and purely based on the latest and updated scientific findings, which means the story may become a true story in the coming years.

This book is based on the lecture notes of a one-semester course on black hole astrophysics given by the author and is aimed at advanced undergraduate and graduate students with an interest in astrophysics. The material included goes beyond that found in classic textbooks and presents details on astrophysical manifestations of black holes. In particular, jet physics and detailed accounts of objects like microquasars, active galactic nuclei, gamma-ray bursts, and ultra-luminous X-ray sources are covered, as well as advanced topics like black holes in alternative theories of gravity. The author avoids unnecessary technicalities and to some degree the book is self-contained. The reader will find some basic general relativity tools in Chapter 1. The appendices provide some additional mathematical details that will be useful for further study, and a guide to the bibliography on the subject.

A scientist randomly discovers one of the most important findings of all the time. He shares his finding only with one of his old friends and shorty after that disappear. For a period of time nobody, even the scientist himself knows where he is or if he is kidnaped. After going through a series of events finally he realizes that he is no longer on Earth and is in another universe. In the new universe he finds out that his original universe is a baby universe in a bigger one which he names it the mother universe. In the mother universe, which has completely different physical, chemical and biological properties, he first find several living creatures from Earth and other solar systems in the Milky Way Galaxy, and later finds out about the real inhabitants of the mother universe. He stays in the mother universe for a period of time which is equal to sixteen years on Earth and finally request from the scientists in the mother universe to be returned to his own original home, the Earth. During his stay in the mother universe he finds new friends and learns many new scientific data. He realizes that the whole structure of the mother universe is different than his own original universe. The creatures in the mother universe are much more advanced than him. Since the two universes share space in certain parts and overlap, during his stay in the mother universe, in several occasions he and his new friends visit Earth, but cannot communicate with people on Earth, because they are in two different worlds with different laws of physics. Finally, in spite of extreme weak chance, the original inhabitants in the mother universe facilitate his return to Earth. After safe return to Earth he finds out that he has been considered as a dead person and he should prove his identity.
