Negative Energy, Wormholes and Warp Drive; Extreme Physics; by Lawrence H. Ford and Thomas A. Roman; 6 Page(s)

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 (originally published January 2000)

Quantum Teleportation; Extreme Physics; by Anton Zeilinger; 9 Page(s)

The science-fiction dream of "beaming" objects from place to place is now a reality - at least for particles of light (originally published April 2000)

Parallel Universes; Extreme Physics; by Max Tegmark; 12 Page(s)

Not just a staple of science fiction, other universes are a direct implication of cosmological observations (originally published May 2003)

Information in the Holographic Universe; Extreme Physics; by Jacob D. Bekenstein; 8 Page(s)

Theoretical results about black holes suggest that the universe could be like a gigantic hologram (originally published August 2003)

The Future of String Theory: A Conversation with Brian Greene; Extreme Physics; by George Musser; 6 Page(s)

The physicist and best-selling author demystifies the ultimate theories of space and time, the nature of genius, multiple universes, and more (originally published November 2003)

Atoms of Space and Time; Extreme Physics; by Lee Smolin; 10 Page(s)

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 (originally published January 2004)

The Dawn of Physics beyond the Standard Model; Extreme Physics; by Gordon Kane; 8 Page(s)

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 (originally published June 2003)
