dark energy (astronomy)

What is a black hole? What is dark matter and what is it made of? How do scientists discover black holes and dark matter if they can't be seen? What do scientists know about these mysterious parts of the universe and what do they still hope to find out? Budding astronomers will learn the answers to these questions and more.

"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.

An illustrated discussion of space phenomena, such as supernovas, black holes, and dark energy, which scientists, including Dr. Alex Fillippenka and his High-Z Supernova Search Team, believe are pushing the universe apart at an accelerated rate. Includes glossary.

"An examination of the science behind the physical concepts of mass and matter, including relevant theories and history-making discoveries as well as topics of current and future research"--Provided by publisher.

Reports on the efforts of astronomers to study the expanding universe and to understand "dark energy," a force that seems to be determining the size, shape, and future life of the universe.

Describes how contemporary scientists have used Einstein's theory of general relativity to use space itself as a telescope. Explains how this tool furthers the search for dark matter and dark energy.

Explains some of the progress being made by scientists seeking to understand the composition of the universe, and looks at how Albert Einstein's theories are proving useful in the quest.

Presents a collection of sixteen articles that discuss scientific theories on the evolution of the universe.

Contains an illustrated discussion of space phenomena such as supernovae, black holes, and dark energy, which scientists such as Dr. Alex Fillippenka and his High-Z Supernova Search Team believe is pushing the universe apart at an accerating rate. 'Includes glossary.
