Evalyn Gates, a talented astrophysicist, transports readers to the edge of contemporary science to explore the revolutionary tool--?Einstein's telescope?--that is unlocking the secrets of the Universe. Einstein's telescope, or gravitational lensing, is so-called for the way gravity causes space to distort and allow massive objects to act like ?lenses,? amplifying and distorting the images of objects behind them. By allowing for the detection of mass where no light is found, scientists can map out the distribution of dark matter and come a step closer to teasing out the effects of dark energy on the Universe--which may forever upend long-held notions about where the Universe came from and where it is going.
Scientists now agree that over 95% of the known universe is made up of "dark matter" and "dark energy." Unfortunately, none of them can agree on just what these "dark" entities consist of. Evalyn Gates documents the string of breakthroughs and discoveries that slowly transformed fantastic theories of this mystifying invisible ether into scientific fact, including a clear and concise analysis of Einstein's theory of relativity. She then discusses how futuristic technologies are aiding today's astronomers and physicists in their quest to capture these pseudo-substances, which may form the essence of everything.
