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

By Leonard Susskind

Quantum Teleportation

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

By Anton Zeilinger

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

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

By Chris Llewellyn Smith

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
