  forces   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.
