The Theory Formerly known as Strings
The Theory of Everything is emerging as one in which not only strings but also membranes and black holes play a role
Features
The Large Hadron Collider
The Large Hadron Collider will be a particle accelerator of unprecedented energy and complexity, a global collaboration to uncover an exotic new layer of reality
The Asymmetry between Matter and Anti-Matter
New accelerators are searching for violations in a FUNDAMENTAL SYMMETRY OF NATURE, throwing open a window to physics beyond the known
Simple Rules for a Complex Quantum World
An exciting new fundamental discipline of research combines information science and quantum mechanics
Quantum Teleportation
The science-fiction dream of "beaming" objects from place to place is now a reality--at least for particles of light
Plenty of Room, Indeed
There is plenty of room for practical innovation at the nanoscale. But first, scientists have to understand the unique physics that governs matter there
Negative Wormholes Energy, and Warp Drive
The construction of wormholes and warp drive would require a very unusual form of energy. But the same laws of physics that allow this "negative energy" also appear to limit its behavior
Frozen Light
Slowing a beam of light to a halt may pave the way for new optical communications technology, tabletop black holes and quantum computers
Extreme Light
Focusing light with the power of 1,000 HOOVER DAMS onto a point the size of A CELL NUCLEUS accelerates electrons to the speed of light in a femtosecond
Detecting Massive Neutrinos
A giant detector in the heart of Mount Ikenoyama in Japan has demonstrated that neutrinos metamorphose in flight, strongly suggesting that these ghostly particles have mass
Black Holes and the Information Paradox
What happens to the information in matter destroyed by a black hole? Searching for that answer, physicists are groping toward a quantum theory of gravity
