New Horizons in Science

The Large Hadron Collider, the world’s largest and most powerful particle accelerator, will begin operation this year in a quest to answer some of the most intriguing questions in physics. One of its missions will be to search for the Higgs boson, which Steven Weinberg predicted in a paper in 1967—nearly half a century ago. An even more exciting possibility is that the collider will reveal something about the nature of the mysterious dark matter that makes up most of the universe. Finally, the LHC may shed light on the theory of supersymmetry. Weinberg will give us a heads-up on what to watch for in the coming months.
