In this issue:
Negative Energy, Wormholes and Warp Drive by Lawrence H. Ford and Thomas A. Roman
The construction of wormholes and warp drive would require a very unusual form of energy. Unfortunately, the same laws of physics that allow the existence of this "negative energy" also appear to limit its behavior
Quantum Teleportation by Anton Zeilinger
The science-fiction dream of "beaming" objects from place to place is now a reality - at least for particles of light
Parallel Universes by Max Tegmark
Not just a staple of science fiction, other universes are a direct implication of cosmological observations
Information in the Holographic Universe by Jacob D. Bekenstein
Theoretical results about black holes suggest that the universe could be like a gigantic hologram
The Future of String Theory -- A Conversation with Brian Greene by George Musser
The physicist and best-selling author demystifies the ultimate theories of space and time, the nature of genius, multiple universes, and more
Atoms of Space and Time by Lee Smolin
We perceive space and time to be continuous, but if the amazing theory of loop quantum gravity is correct, they actually come in discrete pieces
The Dawn of Physics Beyond the Standard Model by Gordon Kane
The Standard Model of particle physics is at a pivotal moment in its history: it is both at the height of its success and on the verge of being surpassed
