**“Splendidly satisfying reading, designed for a nonspecialist audience.”—Kirkus Reviews, starred review** In 1936, Albert Einstein published a paper demonstrating that bending of space caused by gravity would allow massive objects to act like lenses, amplifying and distorting the images of objects behind them. Even as that work went to press, he dismissed the possibility of any practical applications, concluding that while a star can act as a telescope to magnify a more distant star behind it, there was simply no chance of observing this phenomenon. It turns out that Einstein vastly underestimated the ingenuity of future astronomers and astrophysicists. In Einstein’s Telescope, Evalyn Gates takes us to the leading edge of contemporary science where, using the theory of general relativity – the last major revolution in our understanding of the Universe – scientists have discovered that it is possible to use space itself as a telescope. Far more powerful than anything we could ever hope to build here on Earth, Einstein’s Telescope uses the warps and dimples in Einstein’s audacious description of space and time as giant cosmic lenses that allow us to see the invisible.
