Scientists are on the verge of uncovering the secrets of the universe. But they cannot fully know it unless humans sacrifice their own lives. Text written in Chinese characters.

"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,. . . this text explores the development and evaluation of scientific theories behind dark energy. Students will learn about the tools and methods scientists use to unravel dark energy's origins, dynamics, and effects on the universe"--Provided by publisher.

What is the true nature of the fabrics of spacetime? Where does humankind belong in the scheme of the universe? How exactly is the universe alive within us? Let renowned astrophysicist and acclaimed author Neil deGrasse Tyson guide you through these baffling mysteries of the cosmos.

Examines the scientific discovery that mankind only knows about four percent of the universe--meaning ninety-six percent is unknown--and discusses the efforts of scientists to discover "dark" matter and energy, bitter rivals between professionals, and the eureka moments that have altered the way people view the universe.

"The author shares 101 letters from people across the globe who have sought him out in search of scientific answers"--OCLC.

" . . . begins in Earth's neighborhood, explaining the nature of the Solar System, the stars in our night sky, and the Milky Way . . . moves out past nearby galaxies--and back in time--to the horizon of the observable universe, which contains over a hundred billion galaxies, each with billions of stars, many orbited by planets, some of which may host life. These visible objects in space sit in a web of dark matter, mysterious stuff we cannot see or yet understand . . . traces the evolution of the universe from the Big Bang fourteen billion years ago, past the birth of the Sun and our planets, to today and beyond . . . explains cutting-edge debates about such perplexing phenomena as the accelerating expansion of the universe and the possibility that our universe is only one of many"--Publisher.

"An illustrated exploration of the principles, laws, and wonders that rule our universe, our solar system, our world, and our daily lives"---Provided by publisher.

This book tells the story of Neil deGrasse Tyson. When Neil was nine years old, he visited the Hayden Planetarium in New York City. He found he could learn more about space by studying science. Today Neil is an activist, and educator, and a television personality. He is known as America's science teacher and is now the director of the Hayden Planetarium.

A guide to astrophysics for young readers that discusses extraterrestrials, galaxies, dark matter, dark energy, and more.
