The Hunt for Dark Matter and Dark Energy in the UniverseBook - 2009
Dark energy. Dark matter. These strange and invisible substancesdon't just sound mysterious: their unexpected appearance in thecosmic census is upending long-held notions about the nature of theUniverse. Astronomers have long known that the Universe isexpanding, but everything they could see indicated that gravityshould be slowing this spread. Instead, it appears that theUniverse is accelerating its expansion and that something strongerthan gravity --dark energy -- is at work. In Einstein'sTelescope Evalyn Gates, a University of Chicago astrophysicist,transports us to the edge of contemporary science to explore therevolutionary tool that unlocks the secrets of theselittle-understood cosmic constituents. Based on Einstein's theoryof general relativity, gravitational lensing, or "Einstein'sTelescope," is enabling new discoveries that are taking us towardthe next revolution in scientific thinking -- one that may changeforever our notions of where the Universe came from and where it isgoing.
