The ancient Greeks speculated that it might be air, fire or water. A century ago, physicists felt sure it was the atom. Today, we believe that the deepest layer of reality is populated by a diverse ...

Particles known as tensor mesons are created when high-energy photons interact. These mesons have now been proposed to have a larger effect on photon behavior than previously thought, and provide a ...

Superstring theory is not entirely beyond the reach of observation. It predicts a large negative cosmological constant and astronomers are pretty certain that the value is small positive. That's one ...

This week, this enormous scientific facility, ten years in the making, will begin its hunt for the most elusive particles in ...
