||A unified theory for all forces?
This year's prize paves
the way for a more fundamental future description of the forces
in nature. The electromagnetic, weak and strong forces have
much in common and are perhaps different aspects of a single
force. They also appear to have the same strength at very high
energies, especially if 'supersymmetric' particles exist. It
may even be possible to include gravity if theories which treat
matter as small vibrating strings are correct.
