Experiments at CERN and elsewhere should let us complete the Standard Model of particle physics, but a unified theory of all forces will probably require radically new ideas

The Theory of Everything is emerging as one in which not only strings but also membranes and black holes play a role

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

An exciting new fundamental discipline of research combines information science and quantum mechanics

The science-fiction dream of "beaming" objects from place to place is now a reality--at least for particles of light

Slowing a beam of light to a halt may pave the way for new optical communications technology, tabletop black holes and quantum computers

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

New accelerators are searching for violations in a FUNDAMENTAL SYMMETRY OF NATURE, throwing open a window to physics beyond the known

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

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

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

There is plenty of room for practical innovation at the nanoscale. But first, scientists have to understand the unique physics that governs matter there
