Quanta are ultra—small particles, the building blocks of "everything", space is trillions of stars and constantly expanding galaxies. Life in the vast expanses of the universe is inseparable from interactions on the scale of quarks. Combining these dimensions, the authors of the book, physicists, conduct a dialogue in search of answers to the most fundamental questions of science:- Where does matter come from in the universe?- Is matter eternal?- How to unravel the "chemistry" of heaven?- Why do stars explode when they die?- What does the "theory of everything" look like?With the authors of this book, physicists, we will dive into the deep past of the Universe and look into its distant future through the "optics" of the quantum world, and the illustrations of this book will make this study more understandable.
