Goal is to Explore the Fundamental Interactions of Energy, Matter, Time,

and Space

  • Understand the unification of fundamental particles and forces and the mysterious forms of unseen energy and matter that dominate the universe

  • Search for possible new dimensions of space

 Connections between the physics of

elementary particles and the physics that

determines the structure of the universe

The scientific context discovery
The Scientific Context - Discovery

Plans for FY 2007  R&D Investment in Future Initiatives:

  • International Linear Collider

  • new neutrino experiments – accelerator & reactor

  • long-term accelerator technologies

  • Dark Energy - Increase R&D for ground- and space-based concepts

  • We are entering the age of the Terascale energies

    • The reigning theory (Standard Model) is as precise as it is incomplete.

    • How the weak and electromagnetic forces unify is a mystery …but the consequences are likely dramatic

  • Dark Energy & Dark Matter (what the … is it?)

  • Neutrinos – what are they and how do they interact?
