The Missing Antimatter

In the first fractions of a second after the Big Bang lingers a question at the heart of our very existence: why does the universe contain matter but almost no antimatter? The laws of physics tell us that equal amounts of matter and antimatter were produced in the early universe—but then something odd happened. Matter won out over antimatter; had it not, the universe today would be dark and barren. But how and when did this occur? In The Mystery of the Missing Antimatter, Helen Quinn and Yossi Nir guide readers into the very heart of this mystery—and along the way offer an exhilarating grand tour of cutting-edge physics.

As we know that when the Universe was starting, Matter and Anti-Matter were made in equal quantity, then in today's time we get to see only Matter all around us, where did that Anti-Matter go. This question remains a mystery till date. So in this book, I have first collected the definitions of Antimatter from various mediums and have written them first and after that I have presented the answer to what was called Anti Matter on the basis of my research, which is the last topic of this book.

'Overall, the text is very well written in a style that is precise yet easy to understand and interesting to follow … It does not refer to scientific or other publications or suggest further reading, but is completely self-contained. This makes it highly accessible for non-experts. It is intended for ‘serious readers with some general background knowledge in physics, although no specialist knowledge is required’. And it can indeed be recommended to any reader with a scientific interest in the subject, and also as a good recreational read for experts. This is even more true due to the excellent quality of the paper and the print, and the nice format and overall making of the book.'Contemporary PhysicsEach elementary particle contained within every known substance has an almost identical twin called its antiparticle. Existing data clearly indicate that equal numbers of particles and antiparticles were initially created soon after the birth of the universe. Despite this, all objects around us, as well as all the stars in all the known galaxies, are made of particles, while antiparticles have almost completely vanished. The reasons behind this disappearance are not yet fully known. Uncovering them will allow us to not only penetrate much deeper into the structure of matter, but also to understand the secret mechanisms that determine the genesis and development of our immense universe. That is why explaining the mystery of the missing antimatter is currently considered to be one of the main tasks of particle physics.This book tells the story of all the achievements in solving the problem of the missing antiparticles including the latest developments in the field. It is written by Prof. Guennadi Borissov, an international expert in this subject. It is intended for serious readers with some general background knowledge in physics, although no specialist knowledge is required. All phenomena observed in the microworld of particles are explained in simple terms using well-known examples from ordinary life. Starting with a description and discussion of the main properties of particles and antiparticles, the book details the important stages in the research that has brought scientists closer to solving one of the greatest enigmas of nature.

Einstein's equation E = mc2 is often said to mean that energy can be converted into matter. More accurately, energy can be converted to matter and antimatter. During the first moments of the Big Bang, the universe was smaller, hotter and energy was everywhere. As the universe expanded and cooled, the energy converted into matter and antimatter. According to our best understanding, these two substances should have been created in equal quantities. However when we look out into the cosmos we see only matter and no antimatter. The absence of antimatter is one of the Big Mysteries of modern physics. In this video, Fermilab's Dr. Don Lincoln explains the problem, although doesn't answer it. The answer, as in all Big Mysteries, is still unknown and one of the leading research topics of contemporary science.

The Lorentz invariant Dirac equation upon which our deepest understanding of the most fundamental Quantum Mechanics is based,Äîexhibits perfect discrete symmetries of Charge Conjugation C, Parity P and Time T reversal. Not only does the Dirac equation obey these three symmetries CPT, but also all the possible combinations of these symmetries, i.e., CT, CP, PT and CPT. When it comes to the C-symmetry, what this means is that,Äîcontrary to physical and natural reality,Äîthe Universe must contain equal portions of matter and antimatter. Obviously,Äîthis state of affairs that the Dirac equation leads to predictions that are contrary of observations,Äîthis,Äîis based on the notion that the Dirac equation in its bare form as handed to us by Dirac is a correct description of reality on this front. In this chapter, we present a fundamental theoretical argument to the effect that: a symmetry violating curved spacetime version of the Dirac equation may be a perdurable solution to this long standing conundrum.

This book introduces the world of antimatter without using technical language or equations. The author shows how the quest for symmetry in physics slowly revealed the properties of antimatter. When large particle accelerators came on line, the antimatter debris of collisions provided new clues on its properties. This is a fast-paced and lucid account of how science fiction became fact.

A prize-winning science writer provides a history of the 40-year search for the Higgs boson, also known as the "God" particle, and the intense rivalries, clashing egos and grand ambition that led to a world-changing discovery.

“A great read… Goldberg is an excellent guide.”—Mario Livio, bestselling author of The Golden Ratio Physicist Dave Goldberg speeds across space, time and everything in between showing that our elegant universe—from the Higgs boson to antimatter to the most massive group of galaxies—is shaped by hidden symmetries that have driven all our recent discoveries about the universe and all the ones to come. Why is the sky dark at night? If there is anti-matter, can there be anti-people? Why are past, present, and future our only options? Saluting the brilliant but unsung female mathematician Emmy Noether as well as other giants of physics, Goldberg answers these questions and more, exuberantly demonstrating that symmetry is the big idea—and the key to what lies ahead.

Antimatter consists of particles that are mirror images of those of matter. And should a particle of antimatter meet its matter counterpart, both are annihilated in a spectacular burst of energy. Science fiction? No, science fact.

A vivid and captivating narrative about how modern science broke free of ancient philosophy, and how theoretical physics is returning to its unscientific roots In the early seventeenth century Galileo broke free from the hold of ancient Platonic and Aristotelian philosophy. He drastically changed the framework through which we view the natural world when he asserted that we should base our theory of reality on what we can observe rather than pure thought. In the process, he invented what we would come to call science. This set the stage for all the breakthroughs that followed--from Kepler to Newton to Einstein. But in the early twentieth century when quantum physics, with its deeply complex mathematics, entered into the picture, something began to change. Many physicists began looking to the equations first and physical reality second. As we investigate realms further and further from what we can see and what we can test, we must look to elegant, aesthetically pleasing equations to develop our conception of what reality is. As a result, much of theoretical physics today is something more akin to the philosophy of Plato than the science to which the physicists are heirs. In The Dream Universe, Lindley asks what is science when it becomes completely untethered from measurable phenomena?
