"The Big Bang theory describes the very beginnings of the universe, when it was infinitesimally small and infinitely dense, and follows its rapid expansion and evolution, from the formation of nuclei within the first few minutes to the creation of the first galaxies a billion years later. The Big Bang theory is a cornerstone of modern cosmology, and although astronomers cannot directly observe the birth of the universe, the theory is widely accepted...

"Scientists believe that the universe is mostly made up of dark matter, a mysterious substance that is different from the ordinary matter people can touch, smell, see, and interact with. Dark matter cannot be directly observed, but it can be studied by examining its effect on ordinary matter. Simplified explanations of complex scientific concepts and dynamic images will help students understand how physicists employ Kepler's laws of planetary motion,...

"According to many science fiction books and movies, antimatter is dangerous stuff--stuff that would blow up if it comes into contact with normal matter. Antimatter and normal matter will annihilate one another in a burst of energy, and if that burst could be captured, antimatter would provide vast amounts of power. Enhanced by detailed diagrams and illuminating sidebars, this engaging text uses comprehensible analogies to everyday experiences to...

"Cosmic inflation is the theory that the early universe went through fast, exponential expansion for a fraction of a second after the Big Bang and then slowed down to the current rate of expansion. Simplified explanations of complex scientific concepts such as dark energy, dark matter, and the cosmic microwave background and dynamic images will help students comprehend how the study of cosmic inflation has reshaped our understanding of how the universe...

"Dark energy is a mysterious force causing the universe to expand in an accelerating manner. Although Edwin Hubble discovered observational proof of expansion in 1929, the first direct evidence for dark energy came from supernova observations in the late 1990s. Untangling complex physics theories with accessible language, informative sidebars, and captivating imagery, this text explores the development and evaluation of scientific theories behind...

"Gravity causes an apple to fall to the ground and keeps the moon in orbit around Earth. But it can also trap light for infinity in a dying star and ripple across the cosmos carrying the news of a massive collision between two distant black holes. With accessible language and breathtaking NASA images, students will explore the theory of gravity, from Newton's law of universal gravitation to Einstein's general relativity and beyond. This text supports...
