Weird Science (IMAGE) University of Chicago Caption Galaxies can warp space and time, distorting our view of distant objects, much the way this plexiglass lens distorts the appearance of University astrophysicst Evalyn Gates. Astrophysicists use this effect, called gravitational lensing, in their studies of the cosmos. Gates explains how in her new book, "Einstein's Telescope." W.W. Norton will release the book Feb. 23.
